Vented nipple: Helps avoid gassiness as the bottle is vented through our unique air-control system
Mimics natural feeding behavior: Supports easy transition from 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
Calma doesn't drip: You can turn Calma upside down and it still won't drip. Your baby needs to apply a certain level of vacuum in order to get milk out
One size/shape nipple: For all stages of breast milk feeding. The flow, shape and length of Calma are designed to suit your baby's needs as your baby grows
Compatible with all Medela breast milk bottles
Breastfeeding must be well established before introducing Calma
Made without BPA: All parts that come into contact with breast milk are not made with BPA
