Chicco's 0month+ slow flow silicone teat is part of the Natural Feeling range, designed by Chicco to simulate breastfeeding. Made of soft and flexible silicone material, the Natural Feeling teat 0month+ helps facilitate the alternation between breast and bottle. The particular shape of the Chicco 0month+ NaturalFeeling teat that allows it to stay full of milk and the combination with the double valve, avoids the ingestion of air, helping to prevent colic.
