Made of soft and flexible silicone material, the Natural Feeling 0m + teat facilitates the alternation between breast and bottle, giving breastfeeding moments the right serenity. The particular shape of the NaturalFeeling 0 months Chicco teat that allows it to always remain full of milk and the combination with the double valve, avoids the ingestion of air preventing colic. Medium Flow The Natural Feeling 2m + Medium Flow Teat is designed by Chicco to give the newborn the most natural experience possible during the breastfeeding period. Its wide and rounded shape in soft "mother effect" silicone allows the little one to have the right grip without getting tired. Thanks to the double anti-colic valve, the Chicco NaturalFeeling 2m + teat also prevents the ingestion of air due to colic. The Natural Feeling Medium Flow Teat is ideal for babies over 2 months who need more milk flow than younger babies. It is always full of milk and allows a natural latch and suck , just like a mother's breast. It favours a comfortable position for newborns and the flow makes it ideal for the first feedings.
