Safe soothing has never been smarter! Dr. Brown's Prevent Pacifiers are as adorable as they are effective. Designed by a paediatric dentist, the 100% silicone bulb features a patented suction-free air channel and thin bulb stem that reduce pressure inside baby's mouth, helping prevent dental issues such as posterior crossbite down the road. Prevent Pacifiers have a size for most ages, ranging from 0m to 18m. The bulb is taste-free, odourless, and keeps its unique shape over time. , , Available in playful designs featuring a variety of colours, patterns and animal friends, the fun-but-functional Classic Shield fits most little faces. Prevent Pacifiers are easy to clean and are dishwasher (top rack) and sterilizer safe. Electric sterilization and boiling water only do not sterilize baby pacifiers in the microwave.
