The silicone nipple with a flexible diaphragm promotes a natural sucking rhythm and prevents air intake. Its balance membrane valve adjusts to the baby's sucking intensity, mimicking breastfeeding. The pre-formed flat nipple shape supports healthy oral cavity development. Made from hygienic, soft silicone, it provides a breast-like feel. The bottle is easy to disassemble for cleaning and stimulates the baby's motor nervous system. Clinically tested, BPA-free, and approved by 96% of mothers.
