What is the difference between teats made of latex and of silicone?
NUK Latex teatsare made of natural latex, a high-quality, natural material. Latex is particularly durable - it possesses excellent resistance to pulling, helps prevent tears from splitting further and is extremely elastic. As latex is a natural material the fat in the nourishment can cause it to age. It also needs to be stored carefully, as direct sunlight ages the natural material more quickly. A rule of the thumb is that a latex teat should be replaced eve ry 4 - 6 weeks, and certainly once it starts to become sticky.
Comparative tests conducted, have confirmed that NUK Latex Teats contain no measurable allergenic potential. The important thing for parents with allergy-prone (atopical) children to remember is that even latex teats with less than 30 mg/kg soluble proteins are not safe for people suffering from severe latex allergy. In actual fact there are no latex products that can be said to be fully problem-free for anyone highly allergic to latex! Please keep in mind that this type of allergy is quite rare.
NUK Silicone teats are made of high-quality man-made plastic. The transparent silicone material is particularly temperature-resistant. Even direct sunlight and milk fats do not cause the material to age. Silicone is, however, more easily scratched. A silicone teat should therefore be replaced at the first signs of teeth marks or other damage. This is why NUK silicone soothers are only available in Sizes 1 and 2. A rule of the thumb is that a silicone teat should be replaced every 5 - 8 weeks
Whichever material you decide upon, depends on your particular wishes or preference. Of course you can change from one to the other if you wish. If your baby initially rejects a new latex teat because of its typical taste, then simply boil it for 3 minutes in full-fat milk! This will neutralise the taste, although the teat will then age a little more quickly due to the fat in the milk.
What is the NUK anti-colic air system?
The valve is the heart of the NUK ANTI-COLIC AIR SYSTEM. It operates only during feeding, allowing a continual flow of air into the bottle to maintain a constant air pressure within. This prevents the swallowing of air which is thought to be a common cause of colic. The valve is located on the side of the NUK teat. On latex teats - it is an oblique slit. On silicone teats - it is a small disc in a indented area on the side.
Do the new NUK First Choice Bottles fit into the NUK Baby Food Warmer, NUK Microwave Steriliser and NUK Electric Steam Steriliser?
YES!
With the NUK Baby Food Warmer, both sizes of the NUK Classic and First Choice Bottles fit.
The NUK Microwave Steriliser can fit 3 bottle (either classic or First Choice), and the NUK Electric Steam Steriliser fits both First Choice bottles and/or NUK classic bottles.
Please give us a call on 1800 804918 if you have any further queries regarding this.
Are the FIRST CHOICE Bottles and Teats now the only ones available from NUK?
Our new NUK First Choice generation of bottles is an extension to our already existing bottles, which are recommended by experts (midwives, paediatricians etc.) and have also been tested by mothers. Our "older", that is to say our standard "classic" bottles and vented teats, will continue to be available for purchase.
How can I differentiate between the feed hole sizes of NUK teats?
Here is an overview to help you easily tell the various NUK teats apart!
The hole size marking of NUK teats:
The hole sizes (S, M and L) of NUK teats can be easily identified by the marks on the base of the NUK AIR SYSTEM valve.
- S = extra fine hole - for thin liquids, such as breast milk, or water.
- M = medium hole - for formula or cow's milk
- L = large hole - for thicker feeds
Notice:
On earlier models of our classical teats we used a different method for the hole size marking:
NUK Latex classic narrow-neck teats
- for thin liquids (small holes) are marked with a letter "T" opposite the vent in the suction part.
- for milk (medium hole) are not marked.
- for thicker feeds (large hole) are characterised by a crossed slit at the feed-hole.
NUK Silicone classic narrow-neck teats
- for thin liquids the circle is quarter-shaded.
- for milk the circle is half-shaded.
- for thicker feeds the circle is completely shaded.
The NUK latex teats have become sticky. Can you tell me why this has happened?
Here is some information on our teats that we think you'll find useful.
When the rubber part of the NUK latex teat starts to become sticky and swell up, these are typical ageing characteristics that can appear after approx. 4 to 8 weeks of regular of use. The reason is as follows: NUK latex teats are made from high-quality, natural latex.
The life of a teat will depend on a range of different criteria. The food and even the constituents of the baby's saliva are significant here, the fats in the food accelerating the ageing process. Other external influences, such as the effects of strong direct light or heat can also damage the natural material.
Our tip: Store the teats away from direct heat and sunlight.
Boiling the teats for sterilisation for too long can also cause premature ageing. The rinsed teats should be sterilised either in a NUK steam or microwave steriliser, or boiled in a normal saucepan for 3 minutes. The important factor here is that the teats are placed in the water once it is already boiling.
All NUK teats are subject to stringent controls and are regularly tested.
As our products are also being used successfully world-wide, the highest international quality standard applies - for your assurance.
The NUK bottle is becoming discoloured. What is the reason for this?
NUK baby bottles are made of high quallity polycarbonate that poses absolutely no threat to the baby's health. The legislative authorities have deemed them suitable for use with "foodstuffs", and have no measurable levels of BPA.
Although this PC material is highly suitable for use with baby food, it is not, however, completely resistant to all types of infant drinks. Some types of teas, cordials, and juices may cause discoloration, resulting in a roughening of the surface.
If you have decided to use a sterilising solution such as Miltons, you will notice that this will bleech away the designs and dull the colours over time. This will also cut down on the life of the products.
Our tip: Don't leave baby's drink in the bottle for too long and always rinse the bottle immediately after use.
Can I put NUK bottles in the microwave to heat up the feed or drink?
We strongly advise against both heating up bottles in the microwave.
Moreover, with plastic bottles there is a danger that the material itself may be affected or even become mis-shaped. With excessive microwave use, the material ages more quickly and fine cracks may appear, which cuts down on the life of your bottle.
It must be emphasised that improper use of a microwave whilst heating baby's feed can result in serious burns or scalding of the child's oesophagus. The feed is heated unevenly, and can become very hot in one part, whilst remaining lukewarm in another.
A further danger is the fact that heated-up fluids often don't bubble at their boiling point, but only when they are taken out of the microwave. This sudden effervescing can cause serious scalds. For this reason it is advisable to let the fluid cool down slightly before the microwave door is opened.
Sterilising with a NUK microwave steriliser is perfectly safe if used as per intructions.
Can I put NUK bottles in the dishwasher?
As a general rule our NUK bottles should not be put in the dishwasher. The material is suitable for boiling, being still temperature resistant at over 97° C, which is the optimal temperature for sterilising.
This sterilising temperature is not attainable in the dishwasher. What's more, dishwasher cleaning agents are very aggressive and damage not only the designs but also the material. This causes premature wear of the material and can even result in the bottle breaking. For this reason we DO NOT recommend putting NUK bottles in the dishwasher.
What is the correct way for my child to drink from the NUK Training Cup?
It is a little complicated to describe exactly how your child should be drinking from the Training Beakers, but we will do our best:
When drinking, the rounded edge should be facing upwards, towards your child’s nose. The angled side should face downwards, towards the chin. The wording ‘NUK’ will appear to be upside-down if the beaker is held correctly.
Why did the NUK Magic Cup start leaking?
Please remember that the NUK MAGIC CUP is designed to help infants and toddlers learn to drink without spilling. It is not meant for continuous sucking. In order for the patented system to function correctly and also to prevent injury, a somewhat softer material has been used. This material is more susceptible to damage by teeth marks. We therefore recommend that you give your child the MAGIC CUP really just for drinking out of and for short periods. Using harsh, hard utensils to clean the cup can also damage the welding of the patented negative pressure valve inside the spout. This consists of a thin elastomer disc that is slit in a precision process so that fluid can only penetrate from a sucking action. Abrasive cleaning (especially with a brush) may widen the slit, resulting in insufficient negative pressure, and it will drip. We recommend using special NUK Magic Cup Cleaning Sticks to clean the valve as they are extra soft and shaped especially for this purpose. Likewise the lid should not be opened using hard objects as the soft material can become misshapen and lose its sealing ability.
This material, although completely harmless, does, unfortunately have a limited life span, which can be even more detrimentally affected by concentrated cleaning agents, dishwashers, and even acidic fruit juices.
Our tip: Wash the NUK Magic Cup with warm soapy water immediately after use, avoiding concentrated cleaning agents and dishwashers. Use the NUK Magic Cup Cleaning Sticks to clean the spout, or alternatively you can even use a soft cloth or sponge, pushing it carefully into the spout and applying slight pressure, rotating in the direction of the valve.
Are NUK BPA-Free bottles available?
YES! NUK now has a range of polypropolene (PP) bottles that are 100% BPA-Free. NUK soothers were already BPA-Free.
Click here for more details on the new range.
Are NUK PC plastic Bottles safe in regards to BPA (Bisphenol A)?
NUK Bottles are safe. All NUK bottles are now totally BPA Free, however if you have some old PC bottles, below are details outlining that these are also safe for use.
The level of released BPA in NUK polycarbonate baby bottles has been determined by an independent testing authority to be less than one third of the safe release level established by the European Food Safety Authority.
NUK polycarbonate baby bottles are free of harmful levels of released BPA and are entirely safe.
For more information, please click here to view the company statement.
Why did the Polypropolene Bottle deform in shape?
Bottles made of PP (polypropylene) are marked with the symbol “PP” on the bottle. Always dismantle the bottle for boiling or steam sterilizing (temperatures above 80 ˚C) into its component parts and leave it open, otherwise deformation may result. Certain constituents of drinks (eg orange juice) may discolour the material or affect its odour. This has no effect on the suitability of use or safety of the bottle.
Do not pour water over 40˚C into your bottle, seal tightly with disc and screw ring and allow to cool. The vacuum caused by the cooling effect can damage your bottle. If you use hot water, we suggest that you place the sealing disc on the bottle only once the water has cooled to room temperature. Deformed bottles will not be replaced. On occasion the deformed bottle will retract back to original shape after re-cleaning and sterilising.
