Having a difficult time finding the right pacifier for your baby? NUK sensitive pacifiers feature the original NUK orthodontic nipple shape. Invented over 60 years ago by pediatric dentists and doctors, the NUK pacifier is modeled after the natural shape of mom's nipple while breastfeeding. This makes for an easy transition from breast to pacifier and back. The NUK heart-shaped shield fits perfectly under baby's nose for easier breathing and prevents irritation. Now all NUK pacifiers are available in a reusable storage case that allows for easy cleaning in the microwave. Featuring a 100% silicone design that gently contours to baby's face, preventing marks on their sensitive skin, This pack of 3 sensitive orthodontic pacifiers is ideal for your baby aged 0-6 months.
