Air does not dissolve into the milk. The anti-colic system balances the internal and external air pressure. The baby can be fed continuously without swallowing air.
Slow Flow Only suitable for Wee Baby Anti Colic Bottles. Channels on the teat strengthen the teat structure and prevent constriction. Teat is made from odorless and tasteless natural silicone. Silicone is transparent, easy to clean, and does not become tacky.
