The Philips Avent Anti-colic bottle is designed to keep air away from your baby’s tummy, reducing colic and discomfort. As your baby feeds, the valve in the teat flexes to allow air into the bottle, preventing vacuum buildup and directing the air towards the back of the bottle. This helps minimize colic and discomfort. Babies fed with Philips Avent Anti-colic bottles experience 60% less fussing at night compared to those fed with a competitor’s anti-colic bottle. The ribbed texture of the teat prevents collapse, ensuring uninterrupted, comfortable feeding. Ideal for babies 6 months and older.
