Suitable for 0 Months+ Effective Anti-Colic Feature: Thanks to the Equilibrium membrane, air is channeled into the bottom of the bottle, preventing it from mixing with the milk and entering the baby’s stomach. This reduces discomfort, spit-up, gas, and colic symptoms. Consistent Feeding Rhythm: Ensures a smooth, uninterrupted feeding experience without any breathing difficulties. Perfect Fit for Baby’s Mouth: The Physio anti-colic nipple is designed to fit seamlessly in the baby’s mouth, honoring their natural sucking patterns. The anti-colic valve in the Physio nipple is inactive when combined with the intui-flow ring, allowing the Equilibrium membrane to effectively prevent colic. Gentle and Pliable Silicone Nipple: The Soft Sense finish offers a comforting and natural experience for the baby. Easy to Sterilize and Maintain: Made from polypropylene, the bottle features a detachable base for thorough cleaning, with no concealed spots. It’s sterilizable and suitable for use with microwaves and bottle warmers.
