Clinically proven to reduce colic (at 2 weeks of age babies fed with an Avent bottle showed a trend to less colic than babies fed with a conventional bottle) and fussing (at 2 weeks of age babies fed with an Avent bottle showed a trend to less fussing than babies fed with a conventional bottle), especially at night. The two piece anti-colic system consists of the Avent nipple and adapter ring. The adapter ring is an essential part of the bottle design and must always be used. As your baby feeds, the unique skirt on the Avent nipple flexes to allow air into the bottle instead of your baby's tummy. Like natural breastfeeding your baby controls the milk flow. Five different nipple flow rates are available to fit your baby's growing needs. This BPA-free bottle (0% bisphenol-A) is made from PP polypropylene. This pack contains two nipples with one hole. Made in England.
