The new Dr Brown’s Options™ - the first convertible bottle that can be used with or without the green vent system. The unique internal green vent system continues to create 100% vacuum free feeding, which is clinically proven to help reduce wind related colic. This is what makes 9 out of 10 Healthcare Professionals recommend Dr Brown’s for the relief of wind related colic. As baby becomes more developed the bottle can be used without the green vent system to work more like a conventional, teat-vented bottle. The new Dr Brown’s scalloped designed teat allows air to vent through bottle when green vent system is not used for when baby’s feeding it developed or parents just want the convenience of a teat vented bottle. The Pre-Vent Soother has been developed by a paediatric dentist to help minimise the pressures inside baby's mouth. These pressures can sometimes create dental issues such as cross bites. Palatal pressure is lessened by creating an air channel that reduces suction and spreads apart when baby is sucking. This Patented Suction-Free Air Channel opens up as baby sucks for low pressure comfort. The Dr Brown’s Flexees teether is a super-durable teether, designed for biting and chewing. It features a variety of texture combinations to stimulate the gums and mouth. Flexees® are ergonomically designed to access all teething areas. Freezer safe.
