Specially developed for breastfed babies. Especially as a breastfeeding mum, you occasionally want a window of time when you can entrust your little one to dad or grandparents for feeding. With the 2-pack Lansinoh NaturalWave® teat size XS, bottle feeding can be wonderfully combined with breastfeeding, giving you flexible moments for yourself. The slow-flow teat has been specially developed for breastfed babies and allows them to maintain their natural sucking behaviour. This minimises sucking confusion (clinically proven) and makes it easy to switch between breast and bottle. The teats have a wide base with a non-stick texture and a slight incline so that they are super easy to attach and your little one can close their mouth securely. The NaturalWave® teats are equipped with an anti-colic valve to prevent too much air from ending up in the tummy. As they have a long, round tip and are made of soft, flexible, BPA-free silicone, they fit perfectly in your little one's mouth. The tip is particularly stretchy and can be squeezed very easily so that your little one can control the flow of milk themselves. It is reinforced on the inside to prevent it from buckling. The teats can be cleaned in the dishwasher and sterilised in a water bath or steriliser.
