Dr. Brown’s Options+ 9oz/270ml Wide Neck Replacment Kit

Dr. Brown’s Options+ Wide-Neck Replacement Vent Kit x2 is the replacement for the patented ventilation system on Dr. Brown’s Options+ Wide-Neck bottles. With this internal vent system, the air enters through the bottle and circulates directly to this internal system. Then, the air ends up passing through the ventilation tube to the bottom of the bottle and thus avoiding the negative pressure normally felt in bottles due to vacuum. In fact, it allows the bottles to be 100% vacuum free. Furthermore, this system prevents the aeration of the milk and teat collapse. Additionally, this method allows the baby to feed comfortably as the milk flows freely as in breastfeeding.

In summary, this system has numerous advantages. Mainly, it prevents the baby from ingesting air in order to avoid gas, colic, or burping.
