Developed using evidence-based research, Calma is designed exclusively for breastmilk feeding. Used with a breastmilk bottle that emulates babies’ natural feeding behavior at the breast, supporting easy transition from bottle to breast.

Calma is more than a conventional bottle nipple; it’s designed to support breastmilk feeding, allowing breastmilk to flow when babies create a vacuum so they can feed, pause and breathe—which mimics their breastfeeding behavior. As a result, Calma’s unique vacuum technology allows mothers to provide pumped breastmilk to their babies, and easily transition babies back to feeding at the breast, so you and baby can enjoy the breastfeeding bond longer.

The feeding system is available with a 5-oz bottle or (2) 8-oz bottles, allowing you to accommodate larger feedings throughout the breastfeeding journey, while using the same nipple.
