Baby naturally controls milk flow 
The Airflex Teat works with baby’s natural feeding rhythm. Your baby controls milk flow more like breastfeeding, which can help reduce overeating and spit-up.

A unique skirt system, with a built in one-way air valve at its base flexes to allow air into the bottle to prevent a vacuum, whilst milk flows at a pace that baby controls. This promotes healthy, active feeding and reduces colic.

You may hear the Airflex valve quietly working, but watch as the bubbles move away from the teat – that’s your guarantee that air is going into the bottle, not into baby’s tummy. The naturally shaped teat promotes proper latch-on and makes it easier to combine breast and bottle feeding.
