The silicone nipple features a flexible diaphragm that mimics natural breastfeeding, preventing air intake and promoting the correct sucking rhythm. Its balance membrane valve adjusts to the baby's sucking intensity, encouraging a breastfeeding-like experience. The pre-formed flat nipple shape supports healthy oral cavity development. Made from hygienic, soft silicone, it provides a velvety feel similar to the mother's breast. The bottle is easy to disassemble for cleaning and promotes motor nervous system stimulation in babies. Clinically tested, BPA-free, and approved by 96% of mothers.
