Philips Avent Anti-Colic Bottle Gift Set is designed to prevent air from entering your baby's tummy and reduce colic, discomfort and interruptions during feeding. Thanks to its integrated anti-colic valve, air does not enter your baby's tummy. Our anti-colic valve is designed to prevent air from entering your baby's tummy and reduce gas and discomfort. When your baby feeds, the valve built into the nipple flexes to allow air into the bottle to prevent vacuum build-up and directs air to the back of the bottle. Air is kept in the bottle, away from your baby's tummy, to reduce colic and discomfort. Philips Avent Anti-colic bottle reduces fussiness. Babies fed with Philips Avent Anti-colic bottles experienced 60% less fussiness at night compared to babies fed with a competitor's anti-colic bottle.* The shape of the nipple allows for a secure latch and the ribbed texture helps prevent the nipple from collapsing for comfortable, uninterrupted feeding. Our anti-colic bottle has few parts so it can be assembled quickly and easily. The unique shape of the bottle allows it to be easily held in any direction. With its wide neck and rounded corners, our bottle is easy to clean quickly and thoroughly. Easy cleaning helps ensure more hygienic feeding. The orthodontic and flexible nipple of the pacifier ensures the natural development of the baby's palate, teeth and gums. All our pacifiers are made of silicone, tasteless and odorless. Combine parts from our breast pumps, bottles and cups to create the product that's right for you, whenever you need it. The Philips Avent Anti-Colic Bottle is made from BPA-free material (PP). The Philips Avent anti-colic bottle range offers different nipple flow rates to keep up with your baby's growth. Please note that age indications are approximate as babies grow at different rates. All nipples are available in packs of two: Newborn, Slow, Medium, Fast and Variable and Thick flow. Our anti-colic bottle has been designed to prevent dripping during feeding, for a truly pleasant experience. ​
