Dr. Brown's Options Narrow-Neck Replacement Vent Kit x2

Dr. Brown's Options Narrow-Neck Replacement Vent Kit x2 replaces the vent system of Dr. Brown's Options narrow-neck bottles. This patented ventilation system allows the air to enter through the bottle screw and circulate directly to this internal system. Then, the air ends up passing through the ventilation tube to the bottom of the bottle. Consequently, avoiding the negative pressure normally felt in bottles due to vacuum. Furthermore, this method allows the baby to feed comfortably as the milk flows freely like in the mother's breast. In summary, this system not only prevents the baby from ingesting air to avoid gas, colic, or burping, but it also helps him sleep better. Moreover, since the ventilation system prevents breast milk from being exposed to the air, it does not oxidize its vitamins A, C, and E or lipids. Finally, babies will have a lower risk of otitis due to the lack of pressure.
