The Dr Brown's bottles have been designed with a unique internal green vent system which ensures 100% vacuum free feeding and has been clinically proven to help reduce wind related colic. For older babies whose feeding is more developed, the internal vent system can be removed from the bottle to create a more traditional feeding bottle, and the special scalloped design allows air to vent through the bottle creating a controlled milk flow and letting babies feed easily at their own pace.
Internal vent eliminates the vacuum and air bubbles in the feed helping to reduce colic
Internal vent system and Silicone teat work together allowing a controlled flow so baby can feed at their own pace.
For older babies whose feeding is more developed you may remove the vent system allowing baby to feed from a more conventional vent teat bottle
