Philips Avent Natural Teat prevents contraction and is more like the breast. The comfort of the petals and the natural shape of the teat allow a natural attachment and facilitate the combination of breastfeeding and bottle feeding. Natural hooking thanks to the wider breast-shaped teat The wide breast-like teat provides a natural, breast-like latch on, allowing the baby to combine breastfeeding with bottle feeding. The teat has an ultra-smooth texture designed to mimic the feel of the chest. The flexible spiral design combines with our exclusive and comfortable petals to develop a teat that enables a more natural feeding without shrinking. The anti-colic valve is designed to expel air from the baby's tummy and to help reduce discomfort and colic. Teats with different flow levels The Philips Avent Natural range offers teats with different levels of smoothness and flow for each stage of baby's development. It is recommended to use for newborn.
