The unique anti-colic valve on the Avent 260ml bottle is clinically proven to significantly reduce colic.
Sleep and nutrition are vital to your baby's health and happiness. Unsettled and irritable behaviour, known as fussing, is by far the most commonly known crying behaviour in babies. Clinical studies show that the Avent Bottle significantly reduces colic and fussing. Fussing is reduced especially at night.
Unique Anti-Colic Valve
The two piece anti-colic system consists of the Avent Teat and adapter ring. The adaptor ring is an essential part of the bottle design and must always be used.

The naturally-shaped nipple, combined with the fact that your baby controls milk flow more like breastfeeding, makes it easier to combine breast and bottle. As your baby feeds, the unique skirt on the Avent Teat flexes to allow air into the bottle instead of your baby's tummy.

As your baby feeds, the unique skirt on the AVENT nipple flexes to allow air into the bottle, preventing any vacuum build-up.
This allows your baby to suckle almost as at the breast. Listen for the gentle whistling sound and watch the air bubbles burst on the surface of the milk. That's your guarantee that the air is being released into the bottle — not into your baby's tummy.
