Switching from a baby 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. With Calma, the milk will only flow if your baby works and creates a vacuum to remove the milk. This enables the feeding behavior learned at the breast to be used with Calma.


  • BPA-free - Safe for baby
  • Vented nipple - Helps reduce gassiness as the bottle is vented through our unique air control system
  • Natural feeding behavior - Supports easy transition from baby bottle to breast
  • Research has shown that with Calma, your baby is able to maintain the learned feeding behavior that your baby exhibits when breastfeeding
  • Flow control valve - Allows baby to control milk flow. Milk only flows when baby creates a vacuum
