Frequently Asked Questions (FAQ)

Choose the FAQ topics that interest you

Teats

> Are NUK Latex Teats really safe to use?

Yes – and we can even guarantee that. Our NUK Latex Teats are regularly tested by several independent, prestigious institutes such as the Fresenius Institute and not only satisfy all legal requirements but even exceed them.

> I am using a NUK Bottle but the milk is coming out too fast for my baby, what can I do?

Most NUK Bottles come with a Size 1 (0-6 months) Medium size feed hole as standard however we do also offer replacement teats with Small feed holes. In this instance we would suggest using the teat with a Small feed hole as it will reduce the amount of feed and the speed at which it flows out of the bottle. Small feed holes are particularly suitable for young babies and thin liquids such as breast milk.

> My NUK Teat appears to be collapsing when my baby is feeding, why is this?

During the sterilisation, the NUK Anti-Colic Air System vent may become locked which can cause the teat to collapse during feeding. To ensure it is open and works properly, softly squeeze vent as well as drinking hole of the teat (or the slit of the spout) before each use. This will make sure that the air can flow into the bottle, compensates for the air pressure and once again prevents the teat from collapsing and the baby from swallowing air.

> Can NUK Latex Teats cause allergies?

For years, NUK Latex Teats have been immunologically tested for latex allergens. The results show no measurable risk potential and confirm our positive experiences from over 50 years of soother production. However, there are actually no products made from natural rubber that cause absolutely no problems for people with a latex allergy– even if, like the NUK Latex Teats, they are thoroughly cleaned, so that they contain less than 30 mg/kg of soluble proteins. We recommend the use of silicone teats in such cases. 

> Can I use a NUK First Choice Teat on a NUK Training Bottle to help make it easier for my child to progress from drinking from a bottle to drinking from a cup?

Yes. All NUK First Choice and First Choice Plus Bottles and Teats are interchangeable; the teats, spouts, screw rings and handles can be used with any NUK First Choice or NUK First Choice Plus bottle.

> What is the difference between the NUK First Choice Teats and the new NUK First Choice Plus Teats?

The new NUK First Choice Plus Teat is an improved version of the original NUK First Choice Teat, it features the original NUK orthodontic shaped teat with a new special, super soft zone which adapts perfectly to baby's palate and is especially well accepted by breastfed babies. The improved NUK Anti-Colic Air System which even further reduces the harmful swallowing of air, commonly thought to be the cause of colic, and which also helps prevent the teat from collapsing. NUK First Choice Plus Teats are clinically proven for switching between breast and bottle feeding without any problem. 

> What size teat should I purchase?

NUK Teats are available in Size 1 (for children aged 0-6 months*) and Size 2 (for children aged 6-18 months*). There is a choice of different feed holes to ensure a consistent natural flow regardless of the consistency of the feed: Small for thin liquids such as breast milk, Medium for formula milk and Large for thicker feeds.

*Please note that the age range specified is only a recommendation and may vary by child.

> In hospital I used a NUK Bottle with a disposable, pre-sterilised teat, where can I purchase this type of disposable teat?

Unfortunately this type of teat is not commercially available, however we do offer a similar retail version, the Classic Standard Neck Teat which fits on the Standard Neck Bottle. This teat is made with the same size and shape as the disposable, pre-sterilised teat that is used in most Children’s hospitals, the key difference is that this retail version is not pre sterilised. Classic Neck Bottles and Teats can be purchased directly from the NUK Customer Service line 1800 804 918.

> What is the difference between latex and silicone teats?

The main difference is that latex is a natural product whereas silicone is synthetically produced. As a result, both materials have their own special characteristics.

Latex rubber is particularly flexible, bite and tear-resistant. As latex is a natural material, edible fats and exposure to direct sunlight may make it age somewhat quicker than silicone. At the very latest you should replace a latex teat when it becomes sticky.

The material from which NUK Latex Teats are made is from the milk of the rubber tree. The extraction of this precious natural material is under our continuous scrutiny both locally and during processing. For every soother is checked individually by us!

Unlike latex teats, NUK Silicone Teats are made of a high-quality polymer synthetic material. This transparent silicone is heat and age-resistant as well as being very easy to clean. However, silicone is not as soft and flexible as latex, and is prone to cracking. A silicone teat should be replaced immediately at the first signs of cracking or other damage.

Generally speaking, all teats, whether they are made of silicone or latex, should be replaced every 1 to 2 months.

Which material you choose, depends on your individual wishes or preferences and those of your baby too. Of course, you can switch from one type of teat to the other. 

> Can I buy size 3 NUK Teats?

NUK Teats are only manufactured in two sizes: size 1 for infants from 0 to 6 months, size 2 for babies over 6 months. Silicone teats should only be used up to 18 months because babies’ first teeth can damage the material. In addition, at this age, children usually want to drink on their own – and this is why we recommend using NUK Cups/bottles with drinking spouts.

Of course, the ages given are only recommendations. As a rule, children tend to know themselves which teat size is best for them. Please note that a bottle is not a substitute for a soother! Constant sucking on bottles containing drinks, puree or sweet fruit and vegetable juices can cause tooth decay. 

> Do NUK Teats have a feed hole size indicator?

Yes, this is embossed on the base of the teat itself, directly underneath the NUK Air System: S for Small feed hole, M for Medium and L for Large. Or with the newer First Choice Plus teats, it is embossed on the top size of the teat.

Unlike some other feeding brands, NUK Teats are designed to deliver a consistent flow rate, which simulates natural breastfeeding, regardless of the type of feed. The feed hole sizes are specifically designed to achieve this consistent, optimal flow rate with different feed types, for example the Small feed hole is designed for thinner feeds such as breast milk, Medium is designed for milk or formula and Large for thicker feeds or reflux formula. By offering a choice of different feed holes we can ensure that our bottles deliver the same, optimal, breastfeeding like flow rate even when you feed your child different consistencies of food.

> I would like to try a NUK First Choice Teat but have a bottle from another brand, will the NUK Teat fit my bottle?

Unfortunately not, NUK teats have been specially developed to ensure that they are the perfect fit for our own bottles and therefore will not fit onto any other brand of baby bottle.

> Why is there a small cross cut on the side of my NUK Teat?

This is the NUK Anti-Colic Air System which is found on all NUK Teats. The NUK Anti-Colic Air System is a small cross shaped valve which allows air to flow into the bottle through a vent, stopping baby swallowing air and helping to prevent colic. Occasionally on latex teats the slits on the cross shaped valve can stick together, this is because it is a natural material. If this happens the valve can be easily opened simply by using your finger and thumb to gently prise it open.

Soothers

> Why are NUK Soothers asymmetrically shaped?

The special NUK Teat Shape is based on its natural model: the mother’s nipple as she breastfeeds. The special shape results from the nipple adapting particularly well to a child´s mouth and fitting snugly up against the roof of the mouth and against the tongue below. This teat shape lets babies satisfy their sucking reflex in a very natural way.

The NUK Shape for teats and soothers is designed so that sucking on them requires the same sucking and swallowing movements as breastfeeding. This exercises the lower jaw and facial muscles.

If you use NUK Soothers correctly – to calm your child, to prevent thumb-sucking and to exercise the jaw intensively between meals - then the NUK Shape helps towards natural and healthy jaw development.

> Round soothers versus asymmetrically-shaped ones: which are better?

A lot of mothers think that symmetrically-shaped soothers are more like nipples because they can see a similarity. But: during breastfeeding, the nipple actually changes its shape and so adapts to a child’s mouth and the sucking motion. This shape has been scientifically proven to be right for the jaw, or “orthodontic”, and not the round or cherry shape.

In the 1950s, the dental experts, Dr med. dent. A. Müller and Prof. Dr Dr W. Balters searched for ways to prevent crooked teeth and jaw deformation in children. They found out that these problems were rarer in children who were breastfed. From then on, the two scientists took nature as their model. They discovered that a mother’s nipple changes its shape during breastfeeding to fit a baby’s mouth perfectly, and so they developed the first NUK Teats and Soothers which were anatomically shaped and therefore right for the jaw. The flattened shape of the baglet helps widen the lower jaw, in a way similar to breastfeeding. The domed shape of the top adapts to a baby’s palate as it develops. The neck of the teat is notably flat so that – almost like breastfeeding – a baby’s lips are able to close properly around it. The hole in the teat is not at the tip but on top: this means food stays in your baby’s mouth longer so that it can mix better with the saliva – an important requirement for healthy digestion.

Teats with the typical NUK Shape exercise the lips, tongue and even facial muscles optimally and are still being recommended by orthodontists today. You can find more information under “The NUK Shape”.

> There is water in my NUK Soother after sterilising it, what should I do?

All NUK Soothers feature the NUK Air System which is a valve which allows air to escape through the baglet vent, thus allowing it to stay soft and keep its shape, thereby helping to prevent jaw malformation.

Due to the valve opening, water can sometimes enter the baglet when the soother is boiled or sterlised, if this should happen let the soother cool down and then simply press out the remaining water using your finger and thumb, with the ring facing downwards.

> What makes the teat right for the jaw?

Essentially, a soother should be right for a child’s jaw physiologically and allow enough room for the tongue to have a natural sucking movement. A flattened baglet, with a slightly domed underside, puts the tongue into a natural position and this helps the development of both jaws. It is also important that the soother is soft and flexible. A narrow teat neck (the part that joins the baglet to the mouth plate) only puts minimal pressure on the jaw and the teeth that are waiting to come through. More information can be found under “The NUK Shape”. 

> Is a soother not just as bad for the teeth as thumb-sucking?

Before babies start sucking their thumbs or the corner of a blanket, they should be given a soother that is right for the jaw. A soother is much more flexible than a thumb.

Thumb-sucking over a long period of time may push the top incisors forward and the lower ones back. It can lead to an open bite or the bottom teeth being angled backwards with a receding chin, making subsequent orthodontic treatment necessary. It is also easier to wean a child off a soother – as a thumb is always available. 

> Lots of things are said about soothers: what are the pros and cons

Right after the birth you can do a lot for healthy jaw development: while breastfeeding, a child learns the right sucking-swallowing movement –the basis for later learning stages.

Proper breastfeeding and sucking is needed for healthy mouth and jaw movement, which, in turn, is a requirement for eating and speaking.

A teat that is right for the jaw – shaped like a mother´s nipple – can also help babies suck and drink properly 

An asymmetrically-shaped soother helps babies and toddlers to exercise their mouth and jaw muscles. However, if a soother is just in a baby´s mouth, not being “used”, it should be removed.

Children should not be offered a soother if they do not need one and by no means should honey or other sweet foodstuffs be put on it. Soothers should not be used to keep children quiet. A soother can pacify and help cope with upsetting or stressful situations but it can never replace the care and affection of parents. If a soother falls out of a baby’s mouth while sleeping, it should not be put back as it is no longer needed.

The latest scientific research recommends the use of soothers as a way of helping babies fall asleep, as they can reduce the risk of cot death. In addition, children sleep better through the night if their parents are not present while they are falling asleep.

> Can soothers help guard against cot death?

According to international studies, the use of soothers can actually protect against cot death.Scientists from the American Academy of Pediatrics (AAP)2 examined this hypothesis and assessed relevant international studies from the years 1966 to 2004.

The results:

Children who go to sleep with a soother have a much lower risk of cot death. However, the specific reasons for this have not yet been completely researched.

A little tip: the American Academy of Pediatrics advises always giving soothers to babies until they are one year old, whenever they are going to sleep - day or night.3For the first twelve months, the risk of cot death is not only at its highest; your baby’s natural sucking reflex is also at its strongest. Your baby doesn’t want a soother? That’s also quite normal. Never force your child to accept a soother. 

These simple rules will help you protect your child: 

  • Babies should be placed on their backs to go to sleep: this position has proven to be the safest and best one for children.
  • Babies smoke too – during pregnancy and afterwards as well. Please do not smoke. The risk of cot death increases with every cigarette smoked in your house!
  • A “healthy” sleeping environment is important: the best place is cuddled up in a baby sleeping bag, on a firm mattress, in the baby’s own bed, in the parents’ bedroom.  Babies should not be dressed too warmly – an additional blanket is normally unnecessary – and the room should be aired regularly.
  • Do you have the feeling that your baby is ill or behaving differently? Get some reassurance by taking your baby to the doctor.4

> Is it a problem if babies put soothers in their mouths upside down?

The NUK Shape is taken from nature and so babies makes the same typical sucking, and swallowing movements as when they are breastfeeding. The NUK Soother enables children to satisfy their natural sucking reflex and, at the same time, exercise their jaw muscles between meals.

As the mouth plate of the soother gently presses against the baby’s mouth and chin during sucking, the baglet automatically comes into the right position in the mouth. Most babies turn the soother around themselves in their mouths or spit it out if it is upside down.

Soothers should not be given to babies to keep them quiet or just out of habit. This might lead to babies using soothers only as toys which can be put in the mouth the wrong way. Babies who have had other, symmetrically-shaped soothers before may still be used to putting them in their mouths any way they like. It’s best to take a little time and patiently show your baby which way round the NUK Soother goes, because only when the soother is the right way up can it do its job properly and promote development.

> What should I do if my baby puts the whole soother right in?

Only very rarely do babies put the complete soother in their mouths. If this happens: stay calm. The mouth plate of the NUK Soother has been designed so that it cannot be completely swallowed. Additionally, there are two breathing holes in the mouth plate that let enough air through, even if the soother fills the whole mouth. Calmly and carefully remove the soother from your baby´s mouth.

Background information on sizing and the safe use of our NUK Soothers:
we offer 3 different soother sizes for babies from 0 to 36 months. NUK Soothers have differently sized baglets, but all the mouth plates are the same size regardless for which age. Even those for the tiniest babies have a relatively large mouth plate: thanks to its heart shape, the mouth plate does not cover much of the face or stop breathing through the nose. 

> Wouldn´t a larger mouth plate stop babies putting the whole soother in their mouths?

All NUK Soothers conform to the European standard EN 1400 for soothers, which specifically describes and regulates soothers with a button, as well as soothers with a ring. For example, the design and positioning of the safety breathing holes: the soother button should protrude at least 10mm so that it can be grasped. This does not mean that this model is less safe that a soother with a ring.

> What do I need to know about soother hygiene?

Before your baby uses a new NUK Soother for the first time, you should use a gentle washing-up liquid (e.g. the NUK Bottle Cleanser) to thoroughly clean it and then boil it for approx. 5 minutes or use a steriliser.

If there is a little liquid left in the baglet, either just squeeze it out or leave it to dry. Never put the soother in a dishwasher. One cycle is enough to damage the material. 

Another absolute no-go: licking the soother! Your saliva contains bacteria which can cause tooth decay that you can pass on to your baby. This also applies to spoons and teats.

Rinse the soother with water if it is dirty. NUK Soother Chains are also practical, as a soother can then be attached to your child’s clothes. Now the soother definitely won´t fall on the floor again or get lost. 

N.B: All NUK Soothers have an AIR SYSTEM. A vent allows air to escape from the baglet when it is pressed together by the palate. This means that the teat always fits a child´s mouth perfectly. During sterilising, water can get into the baglet through the vent.

A little tip: after boiling simply press the rest of the water out. 

Sterilising has made our NUK Soother really flat!

Then a vacuum has built up in the soother. This simple trick will help: pull hard once on the teat part. Don’t worry, the teat and mouth plate have been designed to withstand pulling.

Such a vacuum can occur if, after boiling, the AIR SYSTEM is blocked: a vent allows air to escape from the teat part when it is pressed together by the palate. This little device means that the teat always fits a child’s mouth perfectly. If the vacuum doesn’t disappear using our trick, then just send us the soother – we will replace it for free.

> When is it time for a new soother?

Rule of thumb: a latex soother should be replaced every 1 to 2 months, exactly like a toothbrush. At the very latest, once it becomes sticky, it’s time for a new one.

The toothbrush rule also applies to silicone soothers: you should use a new one every 1 to 2 months. Silicone soothers should be immediately replaced at the first signs of bite marks or other damage. Babies should always be given new soothers after they have had an infectious illness (such as a cold or throat infection) to prevent re-infection.

> From which age can I give my baby a soother?

Theoretically right from birth. Babies have a natural sucking reflex that also needs to be satisfied. If you are breastfeeding, then this reflex is satisfied naturally – in the true sense of the word. For some babies, this is enough, while for others a soother may be a great help in calming them down.

> When is it a good idea to use a soother?

First and foremost a soother is something to be sucked and so it can make your baby stronger, give comfort and most of all have a calming effect. If a soother is just in a baby´s mouth, not being “used”, it should be removed.

> When is it time to say goodbye to the soother?

It is time to give up soothers towards the end of your child’s second year. Once children turn three they should be going without a soother.

> Do you have any tips to help to give up soothers?

Talk to your child: explain why it is time to give up using a soother – for example, because your child is getting too big or because the soother is old and tired.

But not overnight; Children should be given time to say goodbye to this trusted friend.

Make a “deal” with your child: the soother can only be used at home, until your child is ready to say goodbye. Another tactic: motivate your child into giving the soother to someone else as a “present” – e.g. to a newborn you both know, as this baby “needs” the soother urgently. Very important: give your child lots of praise when the beloved soother is given away.

Another lovely idea is a figure such as the Soother Fairy or her friends: if the Easter Bunny, Santa or the Soother Fairy visits, then this can make saying goodbye easier. Your child can hand over the soother and receive a small present in exchange. 

> Does NUK have Silicone Age3 Soothers?

Unfortunately NUK Australia currently do not stock Age3 Silicone Soothers. We do stock Age3 Latex Soothers, these are more durable for children of that age as they tend to bite through the silicone.  

Expressing Milk

> Is it possible to express breast milk directly into one of your bottles and then freeze them?

Yes you can express with an electric breast pump such as the NUK Luna directly into a NUK Bottle or the breast milk container that is supplied with our breast pumps. All our plastic bottles and breast milk containers come with a sealing disk and screw ring which makes then leak proof and suitable for freezing. Please note our glass bottles are not suitable for freezing.

> I’m struggling to get enough suction out of my Luna Breast Pump, what am I doing wrong?

There are a number of factors which could be affecting the suction of your pump.

Firstly the basics: check to make sure that if you’re using it in battery mode the batteries are correctly fitted and have sufficient life in them. If you’re using it in mains mode then make sure the plug and mains adapter are correctly inserted.Try adjusting the suction strength controller by moving it in the “+” direction to achieve optimum suction strength.

If you’re still having problems then check to make sure that the lip valve is correctly positioned, if it is damaged then use the replacement lip valve supplied, also check the hard plastic valve (either blue or white) is undamaged. Check that the silicone cushion is correctly fitted, it should be flush with the breast shield, and the connection ring has been tightened.

When you use it always make sure you hold it upright; if you’re using it at an angle it will switch off automatically. Also make sure the breast milk container isn’t full, if it is then replace with a new container and finally ensure that the breast shield is completely flush with your breast.

If you are still having trouble please call our Customer Service Team on 1800 804 918

> My Electric Breast Pump is making unusal noises

The lip valve may not be able to process the amount of milk flow, try turning down the suction strength. Also check that both valves are correctly positioned and undamaged.

The pump will make a rattling sound if shaken because of the automatic cut-off. 

> Can I buy replacement parts for my Luna or E-Motion Breast Pump?

You certainly can, simply contact our Customer Service team on 1800 804 918.

Baby Bottles

> Do NUK FIRST CHOICE Bottles fit into the NUK Baby Food Heater and Steriliser?

NUK FIRST CHOICE bottles fit perfectly in all NUK Baby Food Heaters. 

> Can I heat up NUK bottles in the microwave

We do not recommend the use of a microwave when heating bottles are this can damage the bottle and decrease it's lifespan significantly, even only a few seconds in a microwave can cause bubbles and splits in the plastic. 

> What is the purpose of the plastic disc that came with the NUK Bottle that I recently purchased?

This is a sealing disc which sits over the neck of the bottle and prevents milk or feed leaking into the teat. It is particularly useful for preventing spillages whilst you are out and about. The disc also helps when it comes to mixing formula. The disc should be fitted with the NUK logo facing down.

> Can I wash NUK bottles in the dishwasher?

No, most dishwasher detergents are very aggressive and can damage the decoration and material of the bottle which can cause the material to wear prematurely leading to breakage. We recommend washing bottles with the NUK Baby Bottle Cleanser and a little warm water prior to sterilising. NUK’s Baby Bottle Cleanser contains natural ingredients that effectively remove milk protein, pulp and juice residues more effectively than hot soapy water alone.

> How should I clean my NUK bottles?

We recommend washing NUK bottles with the NUK Baby Bottle Cleanser and a little warm water. NUK’s Baby Bottle Cleanser contains natural ingredients that effectively remove milk protein, pulp and juice residues more effectively than hot soapy water alone. After washing, the bottle should be sterilised in a product such as the NUK Vapo Rapid Steam Steriliser or the NUK Microwave Steam Steriliser.

> Where can I buy replacement hoods, sealing discs & screw rings for bottles?

The demand for NUK hoods, screw rings and sealing discs was so low that they are no longer available in shops. Send us an email to info@nuk.com.au or a phone call on 1800 804 918 and we will happily help you.

> Why are there holes in the hood/cap of my NUK baby bottle?

The holes are in fact air vents, all NUK First Choice bottles have this feature which ensures that in the event of a child placing the cap over their mouth and nose at the same time, they are still able to breath.

> Is it safe to use a glass bottle to feed my baby?

Yes, glass bottles are very hygienic and are perfectly safe to feed your baby with as long as they are handled and used correctly. The key benefits of glass over plastic are a higher level of hygiene and durability. Glass bottles are more hygienic than plastic because plastic bottles are more prone to scratches inside the bottle, caused by brushes etc and these scratches can present an ideal ground for residues and germs. It becomes visible when you put carrot juice into a bottle that has been used for a longer period or when the plastic becomes less shiny. Glass bottles are also less likely to loose their shape after significant use. All NUK Glass Bottles are made of toughened Borosilicate glass to minimise the risk of breakage however even toughened glass can still break and thus it is really important that you NEVER leave your child alone with a glass bottle. Glass bottles are not suitable for children that are self feeding or for those who like to hold the bottle themselves, primarily from a safety perspective but also due to the weight of the bottle. You must never use metal spoons to stir a glass bottle as this can cause hairline cracks which can result in a fracture when hot feed is poured in. Also never use force to seal or unseal the bottle and replace it if there is even the slightest sign of damage. You should treat glass bottles in the same delicate way that you treat any other item made of glass in the house in order to prolong it’s usable life.

> What is the right way to hold the NUK Silicone Spout?

It sounds much more complicated than it actually is: your child is drinking correctly when the round part of the spout is pointing upwards towards the nose and the angular side is pointing towards the chin. The word NUK is then upside down. 

> Do you sell insulated covers for your bottles?

We don’t currently have an insulated bottle cover in the range but we are constantly looking to extend and improve our range and thus it maybe something that is added to the range in the future.

> I am finding that when I shake the NUK Bottle to mix the milk formula it is leaking slightly, why is this?

All NUK Bottles come supplied with a sealing disk, this little cap fits over the neck of the bottle, with it in place and the screw ring tightened the bottle is effectively sealed, this prevents milk or feed leaking into the teat or indeed out of the bottle. The sealing disc is particularly useful for preventing spillages whilst you are out and about and it also helps when it comes to mixing formula. Replacement discs can be purchased by contacting us on 1800 804 918 or emailing info@nuk.com.au

> Can I combine bottle and breastfeeding?

We developed the NUK FIRST CHOICE Bottle and Teat System using the latest medical findings on breastfeeding. Combining bottle and breastfeeding is not only uncomplicated, it is also not a problem because all our teats take their shape and function from a mother’s nipple. Would you like to learn more about this subject? Simply click on “The NUK Shape” or watch the video session with our NUK Expert.

> How can I prevent colic when bottle feeding?

When preparing your baby’s formula, always follow the manufacturer’s instructions and make sure that you use the right amounts of water and milk powder. If, after shaking the bottle, froth appears, then let the bottle stand for a while until the froth has dispersed.

The right teat and hole size are very important!

The teat should always be completely full of milk while feeding. Burping is also important after bottle or breastfeeding.

From time to time, babies should be picked up and burped during feeding, because any air that has been swallowed can then come up and escape.

A vent in our NUK Anti-Colic AIR SYSTEM helps prevent a vacuum building up in the bottle: your baby can drink continuously without swallowing air.

While bottle feeding with the special NUK Teat Shape that suits the jaw, the same lip, jaw and tongue muscles as breastfeeding are helped to develop. The natural, inborn drinking movements remain unchanged. In order to make digestion easier during sucking, the milk is mixed with saliva. NUK FIRST CHOICE Teats have the same effect: this comes from having the hole on the upper side of the teat and not at the tip of the teat. You can also find more information on this subject under “The NUK Shape”. 

> There are different drinking holes in the NUK Teats with a vent – how can I tell them apart?

Here is a rundown of how you can easily distinguish between the NUK Teats!

The hole size marking on NUK Teats:

the hole sizes (S, M or L) are easy to see on the rim of the teat under the NUK Air System Vent.

S = extra-fine hole - for thin liquids such as breast milk, infant formula, tea or water
M = medium hole - for formula
L = large hole - for thicker liquids such as reflux formula

Training Bottles & Cups

> Is it possible to purchase replacement spouts for the NUK Training Bottle in latex material?

Unfortunately we don’t offer replacement spouts in latex, we do however offer replacement spouts in silicone, the non-spill spout is softer, more flexible which helps the transition from a teat to the cup without any mess. 

> Can the Silicone Non-Spill Spouts be sterilised?

Yes the Silicone spouts can be sterilised using steam or cold water sterilisation, they can also be sterilised in a NUK Steam or Microwave Steriliser however we do not recommend sterilising in a dishwasher as this can cause material damage. The NUK Baby Bottle Cleanser is recommended for cleaning spouts prior to sterilisation as it removes dried on milk protein, pulp and juice residues more effectively than hot, soapy water alone.

> My 6 month old loves the NUK Training Bottle but has a thirst greater than the 150ml, do you offer an equivalent bottle with a larger capacity?

The NUK Training Bottle is only available in 150ml size but as with all the First Choice and First Choice Plus products it is interchangeable and so you can easily take the handles and spout from your existing 150ml Learner Bottle and add them to an existing 300ml NUK Bottle and then you’ll still have the benefit of a Training Bottle but with a larger capacity. We also offer Winnie The Pooh Active Cup that are 300ml, have a Silicone Non-Spill Spout but without handles.

Cleaning & Sterilising

> I have noticed some brown residue on the silver plate of my NUK Electric Steam Steriliser, is this normal?

The brown residue is the build-up of the minerals in water. The build-up can occur from first use of the NUK Steriliser. Therefore, it is very important to descale the evaporator tray of the steam steriliser as often as possible to prevent a large build up.

To remove residue we recommend pure white vinegar or an equal parts mixture of white vinegar and boiling water, leaving it for up to 30 minutes. If there is already a large deposit on the evaporator tray that is difficult to remove then an all purpose de-scaler can be used.

> I am thinking of purchasing a steriliser from another brand but I like NUK Bottles, will NUK Bottles fit into a competitor’s steriliser?

If you’re using our 150ml bottles then it is likely that they will fit however our 300ml bottles are taller than some of our competitors bottles which may be an issue. To be absolutely sure we recommend using either the NUK Electric Steam Steriliser or NUK Microwave Steriliser to sterilise all NUK Bottles, alternatively you could simply boil them as a means of sterilisation.

> Do the large 300ML NUK Bottles fit into the NUK Electric Steam Steriliser?

Yes all size variants of NUK Bottles will fit into the electric steriliser; it will hold up to 5x NUK First Choice Plus. The NUK Microwave Steriliser will hold up to 3 bottles.

> How long will bottles stay sterile for after sterilisation?

We can only provide advice based on our Steam Steriliser but if the items are kept inside the sealed steriliser they will stay sterile for up to 24 hours, as soon as they are removed they are no longer sterile.

> After I have sterilised my baby’s bottles and teats, how should I dry them?

We would suggest using a drying rack; this is a more hygienic way of drying baby accessories than using a cloth.

> Do I need to clean my Electric Steam Steriliser every time after sterilising?

Regular cleaning will help prevent a build-up of residue from water minerals, which will help keep the steriliser in the best possible condition. The build-up can occur from first use of the NUK Steam Steriliser. Therefore, it is very important to descale the evaporator tray of the steam steriliser as often as possible to prevent a large build up. To remove the build-up we recommend pure white vinegar or an equal parts mixture of white vinegar and boiling water, leaving it for up to 30 minutes. If there is already a large deposit on the evaporator tray that is difficult to remove then an all purpose de-scaler can be used.

Materials

> Which is better: a silicone or a latex soothers?

This is purely a matter of “taste”. Both materials have their advantages. You can, of course, switch between materials. However, once children have their first teeth, we recommend the use of soothers made from latex as it is more bite-resistant than silicone.

The differences:
Latex is obtained from rubber milk and is a high quality natural material.  Once it has been processed, latex is very flexible and durable and this makes it suitable for babies who already have their first teeth. Direct sunlight makes latex age more quickly and it can discolour. This discolouration is also a sign for the mother to get another soother – as a general rule soothers should be replaced every 1-2 months. As latex is a natural product it can be disposed of in an environmentally-friendly way.

NUK Silicone Teats are made of a high-quality synthetic material. Silicone is transparent and particularly heat resistant, even direct sunlight or edible fats (e.g. in milk) do not make it age. However, silicone is prone to small bite marks or other damage. If you notice this, then it is time to replace the silicone soother. 

> What are Bisphenol A (BPA) and polycarbonate (PC)?

The abbreviation, BPA stands for Bisphenol A and it is a raw material used in the manufacture of the synthetic material, polycarbonate (PC). BPA is “embedded” in the material and is firmly bound in it.

PC is a very versatile type of material: it is durable, heat-resistant, nearly unshatterable and transparent. This is why PC is used for countless items in everyday use.

BPA is a starting material for polycarbonate, which is found in many products which we use daily: for example, in plastic bags or milk cartons, food packaging, but also in mobile phones, CDs as well as sunglasses, adhesives or nail polish.

> Are all the NUK Baby Bottles I can buy today, BPA-free?

Yes. Since 1st June, 2011, the sale of baby bottles containing BPA has been prohibited in all countries of the European Union. This means that bottles containing BPA are not allowed to be sold.

In 2012 the Australian Government introduced a voluntary phase out of BPA use in polycarbonate baby bottles.

At NUK, we switched our complete baby bottle production to BPA-free materials, before the EU legal ban on BPA came in force.

 

 

> What alternatives to products containing BPA does NUK offer?

Every material has its own characteristics. That is why NUK offers you numerous alternatives to PC. For example:

Baby bottles made of glass, polypropylene (PP), polyamide (PA) and polyphenylsulfone (PPSU). All the materials used by NUK are continuously subject to safety checks as a matter of course. 

> Why did BPA come under criticism?

There are numerous studies worldwide in which the danger to health caused by the intake of Bisphenol A (BPA) is explored. The results of these studies are not conclusive and over the past months and years have been very inconsistently assessed by different institutes in various countries.

The scientific controversy over a possible danger to health through the effect of BPA on the human organism led to critical public debate and made parents feel extremely unsure. As a precaution and in the light of the confusing information, the European Commission took the decision to ban the use of BPA in the production of baby bottles from 1st March, 2011.

Since 1st June, 2011 the sale of baby bottles containing BPA is no longer allowed in the countries of the European Union. In 2012 the Australian Government introduced a voluntary phase out of BPA use in polycarbonate baby bottles.

> Do soothers also contain BPA?

A NUK Soother consists of different parts. The teat (baglet) is always made of latex or silicone and is therefore 100% BPA-free.  The mouth plate and ring used to be made from polycarbonate (PC).

However, at NUK, we reacted early on to the apprehension of parents and switched the complete production of soothers to BPA-free materials, for example, polypropylene (PP).

All NUK Soothers are therefore BPA-free and clearly marked as such. 

> Can I continue using a polycarbonate soother?

Basically, yes. However, it is generally recommended that all NUK products are washed thoroughly before each use and checked for damage. Damaged soothers should always be replaced.
