Nighttime pacifier that glows in the dark makes it easy to find at night without disturbing baby. The Dr. Brown's PreVent pacifier features a patented Suction-Free Air Channel, helping to reduce the suction and palatal pressure that can create dental issues such as cross bites. Soft, suction-release bulb spreads wider as baby sucks for low-pressure comfort, plus thin-stem design is minimally intrusive on baby’s mouth. Dishwasher and Sterilizer Safe. BPA-free.
