The Two piece anti colic system consists of the Philips Avent teat and adapter ring. As your baby feeds, the unique skirt on the PhilIps Avent teat flexes to allow air into the bottle instead of your baby's tummy. Like natural breastfeeding, your baby controls the milk flow.
Unsettles and irritable behaviour, known as fussing, is far the most commonly known crying behaviour in babies. Clinical studies show that the Philips Avent bottle significantly reduces colic and fussing. Fussing is reduced especially at night.
