This Chicco Perfect 5 teat adapts perfectly to the mouth of baby's aged 4m+ and respects their natural sucking movement. Made of extra soft silicone and featuring a SoftSense™ finish, it perfectly simulates the mother's breast, offering the baby a comfortable feeling that facilitates acceptance. Thanks to its ergonomic shape from being elongated and enlarged, Chicco's Physio Perfect 5 teat favours the peristaltic movement of the tongue during breastfeeding. This teat adapts perfectly to all bottles of the Perfect 5, Well-Being and Original Touch series.
