Plus, if you’ve noticed how plastic can begin to smell over time, you’ll be glad to know this won’t happen with glass. Plastic traps dirt and bacteria, whereas glass won’t. Are glass baby bottles eco-friendly? Due to its particularly natural shape, the NUK teat is accepted well by babies. This means that it is specially suited for babies who are both bottle and breastfeed. Independent market research among 205 mothers, Germany 2018. (99% of the mothers confirmed that the NUK First Choice+ Control bottle does not cause colic).

The NUK Anti-Colic Air System ensures a natural flow to help your baby drink without swallowing air. Glass bottles are also really easy to clean and don’t store dirt or bacteria in the way plastic can. However, given the discovery of this chemical, who’s to say there aren’t more nasties hiding in plastic that we don’t know about yet?We were disappointed the bottle had no protective sleeve available. Since drops and bumps are inevitable, we think many parents would appreciate an extra layer of protection for a glass baby bottle. Glass is also heavier than silicone and plastic. We suggest monitoring your child while they drink from this bottle because its weight could pose a challenge, and older children could move around or become squirmy, increasing the chance of a drop.

Polyamide are synthetic materials with a high level of transparency, which it retains by being chemical-resistant – discolouring and clouding are a thing of the past. Polyamide is BPA-free, but not suitable for the microwave however. NUK Silicone Teats are made from a high-quality synthetic material. The clear silicone material is easily cleaned and highly heat-resistant. Even direct sunlight or edible fats do not age the material. Silicone teats have a neutral taste and smell. However, silicone is slightly less bite and tear-resistant than latex. For this reason, NUK also uses firmer, more bite-resistant silicone material for the size 3 teat. Should a silicone teat have even small bite marks or other signs of damage, it should be replaced immediately. For reasons of hygiene and safety, it is generally recommended to replace all teats – whether latex or silicone – after 1-2 months. However, plastic is neither as heat-resistant as glass and nor as scratchproof. When the bottles are scratched inside, you should replace them, as germs can settle in the scratches more easily. NUK Baby Bottles are made from different materials. The greatest tangible difference is between glass and plastic – both materials are very suitable for baby formula and breast milk. Here you can find some points to help you make your decision.Glass is the classic material for drinking containers – and also for baby foods. Today, with its higher scratch resistance, glass is a particularly resiliant and environmentally-friendly material. NUK only offers products made from borosilicate glass, which, with its cross-linked surface structure is particularly heat-resistant. Thanks to the high level of transparency of the glass you can easily see if there is any milk or other residue still there when cleaning the bottles. The high heat-resistance means you can clean the glass baby bottles as often as you like and even boil them. And should you give older children tea or juice in them, then the glass of the bottle does not discolour. If the food is too hot, the normally blue indicator will turn white. Ideally, the food for feeding should have body temperature (37°C) and corresponds to the mean blue tone on the display. The new Temperature Control function is integrated in NUK First Choice + bottles made of polyamide and polypropylene. Licensed editions are excluded. If you’re worried about glass bottles slipping out of your grasp easily, you can buy special sleeves to give you extra grip. Knowing exactly when baby's feed is at the right temperature can be a challenge. NUK First Choice+ baby bottles now have a built-in Temperature Control indicator located on the bottle's graduation marks that changes colour from blue to white when the bottle's contents are too hot (above the optimal feeding temperature of 37 degrees), so you can be sure your baby's milk is always at a comfortable drinking temperature. This bottle is the ideal choice for combined feeding* as the NUK orthodontic teat simulates the shape of a mother's nipple during breastfeeding which gives baby a natural and familiar drinking sensation. The innovative teat also minimises colics** thanks to the NUK Anti-Colic Air System that ensures a natural flow to help your baby drink without swallowing air.
