The AirFree™ vent is designed to help your baby swallow less air. The teat stays full of milk, even when horizontal, for upright feeding. Reducing the air a baby ingests can help ease common feeding issues like colic, gas and reflux.Features:• The teat stays full of milk, even when the bottle is horizontal, so your baby can drink in a more natural, upright position. This can help reduce reflux, aid digestion, and make feeding time more comfortable for you and your little one.• Unique AirFree™ vent draws air away from the teat, so your baby swallows less air as they drink. This can help reduce common feeding issues such as colic, reflux and gas.• Clinical studies have shown that the Philips Avent bottle reduces colic and fussing*. A valve in the teat prevents vacuum build-up as your baby drinks, allowing uniterupted feeding. This can help reduce colic, gas, spit-up and burping.• The AirFree™ vent can be easily assembled with any Philips Avent Anti-colic and Classic+ bottle. Also cleaning is a breeze, thanks to the bottle's wide-neck, and there only being a few parts to clean.• Material : Bottle Polypropylene.• Teat : Silicone.

• To start, fill the bottle with milk, place the AirFree™ vent over the rim, and screw on the teat.
• Tilt the bottle downwards once to fill the teat, and you're ready to go.
• When feeding, make sure the AirFree™ vent stays on top.
• The teat will stay full of milk, even when it's horizontal, for easier upright feeding.
