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