Chicco Natural Feeling Teat Medium Flow Rate 2 Months and + is a silicone teat with double anti-colic valve for bottles in the same range. Its angled head allows for instinctive feeding and a comfortable position during breastfeeding. Always full of milk, it prevents air ingestion by an anti-colic action. In this way, baby reproduces the same sucking movements as at the breast, naturally positioning his lips on the rounded base. The extra-soft silicone is reminiscent of the softness of the mother's breast.Clinically tested.
