Air enters the bottle collar and routes directly through the internal vent system
The Air channels through the ven tube, bypassing the milk, to the end of the bottle
The vent prevents aeration of the milk, vacuum pressure, and nipple collapse.
Baby feeds comfortably while the milk flows freely, like breastfeeding.
Dr. Brown's Natural Flow® Wide-Neck Bottles feature an ergonomic design that's easy to fill and hold. The silicone nipple has a broader base which some breastfeeding moms prefer.
