The pre-sterilised disposable bags are marked with a scale clearly visible through the Holder for measurement of feed.

The Avent teat is breast-shaped so combining breast and bottle feeding is simple. As your baby feeds, the patented anti-colic skirt of the teat flexes to allow air into the bottle and not your baby's stomach. It is the air babies swallow during feeding which is thought to cause colic. Your baby will enjoy a relaxed, uninterrupted feed - almost like at the breast.
