Chicco Perfect5 Bottle: the revolutionary anti-colic bottle. It is the only biofunctional bottle that adapts to each baby's rhythm and suction intensity during the various times of the day. Thanks to the innovative anti-colic system intui-flow®, it naturally favors the physiological sucking of each baby, to meet all their needs and offer maximum well-being during and after breastfeeding. Characteristics: Proven anti-colic effect: with the Equilibrium membrane. Air enters through the base of the bottle, does not mix with milk and does not enter the baby's tummy, reducing irritability, regurgitation, gas and colic. .Fits perfectly with the baby's mouth: Physio anti-colic teat that adapts perfectly to the baby's mouth and respects the natural sucking behavior. The anti-colic valve of the Physio teat does not work when the intui-flow ring is present, allowing the Equilibrium membrane to activate the anti-colic action.

Sterilizable and compatible with microwave and bottle warmer.
