Philips Avent

The Philips Avent Anti-colic bottle with AirFree vent is designed to reduce feeding issues: colic, gas, and reflux. The AirFree vent keeps the nipple full of milk, not air, while feeding upright. The nipple stays full of milk even when the bottle is horizontal, for upright feeding. By keeping the nipple full of milk, not air, the vent helps reduce the amount of air your baby ingests and ease common feeding issues such as colic, reflux and gas.
