Switching from bottle back to breast has never been easier. Calma
was developed using evidence-based research on babies' natural feeding
behavior so you can enjoy your breastfeeding bond longer.
Calma, the milk will only flow if your baby works to create a vacuum to
remove the milk. This enables the feeding behavior learned at the breast
to be used with Calma. Calma mimics babies' natural feeding behavior,
so baby can feed, pause and breathe, similar to breastfeeding. The
vented nipple is designed to help avoid gassiness.
