Philips AVENT unique AirFree vent is designed to draw air away from the nipple keeping it full of milk.
Philips AVENT Anti-colic Baby Bottle with AirFree Vent 4oz Use Philips AVENT Anti-colic bottles only with Philips AVENT Anti-colic nipples. The shape of the nipple allows for a secure latch, and the ribbed texture helps prevent nipple collapse, for uninterrupted, comfortable feeding. We recommend replacing nipples every 3 months for hygiene reasons. Philips AVENT Anti-colic nipples are available in different flow rates (0m+, 1m+, 3m+ & 6m+), to keep up with your baby’s growth.
