Dr Brown’s Soothers 6- 18 months blue 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. New Butterfly design with 2 Soothers per pack.
