Chicco Bottle Perfect5 Fluxo Normal is a bottle with anti-colic effect that adapts to the baby's rhythm and suction intensity. It features an innovative anti-colic system called intui-flow® that favors physiological sucking and provides maximum well-being during and after breastfeeding. The anti-colic effect is due to the presence of an Equilibrium membrane that allows air to enter through the base of the bottle and does not mix with milk, avoiding irritability, regurgitation, gases and colic. The soft and flexible silicone Physio teat adapts perfectly to the baby's mouth and respects natural suction. Easy to clean and sterilizable. Compatible with microwave and bottle warmer. Suitable for babies over 4 months of age.
