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.
