The Philips Avent Classic Feeding Bottle is designed to make feeding time easy and enjoyable for both you and your little one. Featuring a unique valve in the teat that flexes to allow air into the bottle instead of your baby's tummy, this bottle is clinically proven to reduce colic and discomfort. It also has a unique shape that's easy to hold in any direction, and its wide neck makes filling and cleaning a breeze. With few parts for quick and simple assembly, and a leak-free design, this bottle really is your ticket to stress-free feeding.
