Keep your precious little one happy and comfortable as they feed with the Philips Avent Classic Teat. Made from extra-soft silicone, this teat has a unique ribbed texture that prevents teat collapse for uninterrupted feeding. It also boasts a clinically-proven anti-colic valve which flexes as your bub feeds to allow air into the bottle - preventing vacuum build-up and venting air towards the back of the bottle. It keeps air in the bottle and away from baby’s tummy to help reduce wind, spit-up, discomfort and burping. Featuring a newborn flow rate, this teat is suitable for use from birth.
