The Inclined baby feeding bottle from Chicco is made from polypropylene and is BPA free. It comes with a silicone teat that has an anti-colic valve which prevents the ingestion of air, reducing colic and discomfort after feeding. The soft and elastic teat closely resembles the nipple, and is easily accepted by your baby for an easy switch between bottle and breast feeding. The milk flow rate of the teat suits new-born baby needs and older. The bottle also comes with a protective cap that keeps it clean when not in use.
