Dr.Brown's 2-Pack Prevent Butterfly Shield Stage 2 Pacifier - Blue Developed by a paediatric dentist to help prevent dental issues. All the same benefits as the Regular Shield Prevent Pacifier but with a contoured shield design that helps keep the shield from coming into contact with baby's face. The Patented Suction-Free Air Channel opens up as baby sucks for low pressure comfort helping lower the pressures inside the baby's mouth. These pressures can sometimes create dental issues such as cross bites. Palatial pressure is lessened by creating an air channel that reduces suction and spreads apart when baby is sucking.
