Medela - Calma Bottle Nipple

Paced feeding: With a patented air-vent system, Calma ensures milk flows only when vacuum is created, allowing your baby to drink, pause, and breathe at its own pace.
One size fits all ages: The milk flow is automatically regulated by the strength of the vacuum applied, eliminating the need to adjust nipple flow rates as your baby grows.
Compatible with Medela Bottles: collect, store, and feed using Medela bottles. The included multi-lid prevents any milk from spilling during transportation.
Clean and store: All components of the Calma Nipple fit in the dishwasher (top rack), and once cleaned, they can be stored using the multi-lid and cap provided.
Made in Switzerland and made without BPA.
