Anti-Colic Design: Equipped with an advanced air vent system, the bottle minimizes swallowed air during feeding, reducing the risk of colic and discomfort for the baby. Round-Cut Nipple Opening: The round-cut nipple opening allows milk to flow out consistently and gradually, supporting newborns' sucking ability as they develop.

It is also compatible with SofTouch nipples, offering flexibility as the baby grows.
