Suavinex Zerozero Nipple Silicone Colic One size is recommended for mixed lactation. Prevents ingestion of air whenever it is full of fluid. Ultra-soft and colorful silicone mimics the texture and consistency of the nipple. The teat's mouth is wider and curved base so that the mouth, tongue and jaw muscles are positioned and working in the same way. Angled inclined teat that allows the baby's neck to be correctly positioned resulting in relaxed lactation. Helps prevent reflux and ear infections. Adaptable flow, as its opening allows more or less fluid to pass depending on the baby's suction strength. From 0 months.
