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. Here are the best bottles our editors have highlighted through research. And it's all supported by our parents in the BabyCentre community. Thanks to the flexible silicone material and the wide opening it is very easy to use: simply place the bottle into the sleeve and close it with the button: worrying about glass shards in the family kitchen is now a thing of the past! Even if a bottle does break the shards stay in the sleeve and can be disposed of safely. The transparent narrow window lets you always see how full the bottle is.

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. The product range for alternatives without BPA is wide. Precisely which materials they are, we explain for you here:Suitable for combination feeding* - the extra wide lip support simulates breast feeding as closely as possible

Glass bottles are also really easy to clean and don’t store dirt or bacteria in the way plastic can. 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. When you think of a glass bottle, you probably think of a milk bottle, which shatters dangerously if you drop it. Considering how many times you and your baby will drop their bottle – we know how clumsy you get on 3 hours sleep after all – you want to make sure that a glass baby bottle can withstand babyhood. Plus, the initial thought of giving your baby something made of glass can make you shiver. As every material has its individual advantages and disadvantages, we offer a selection of robust baby drinking bottles made of glass as well as baby drinking bottles made of high-quality polypropylene (PP) and polyamide (PA), naturally free of BPA. The lightweight and unbreakable plastic material of the NUK baby drinking bottles is a good choice when on the go and promotes the learning effect when drinking, as the little ones can easily hold the weight of the bottle themselves without any danger. Baby bottles made of polyamide are highly transparent and come visually closer to the glass bottle. Baby bottles made of polypropylene, on the other hand, can be frozen and heated in the microwave.One of the oldest materials known to man is also used by NUK in the production of baby bottles. Glass is particularly hygienic and heat- resistant. In this process, NUK uses only borosilicate glass, which, with its cross-linked surface structure, wears well and withstands variations in temperature. Using glass as a material for your baby’s bottle removes all worry about chemicals leaching into their milk, as it’s naturally free of toxicity. The transparent sleeve is BPA-free and gives every bottle a new look. Clean the sleeve by rinsing thoroughly by hand. 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.
