NUK Translucent pacifiers feature gender specific and gender neutral colors. Like all NUK pacifiers, the Translucent line features the original NUK orthodontic nipple. Invented over 60 years ago by pediatric dentists and doctors, the NUK pacifier mimics the natural shape of mom's nipple while breastfeeding. This makes for an easy transition from breast to pacifier and back. The asymmetrical nipple naturally fits baby's palate and features a scoop bottom allowing for maximum tongue movement and proper teeth alignment. This, coupled with less pressure on baby's palate, creates a pacifier that best promotes healthy oral development. The NUK heart-shaped shield fits perfectly under baby's nose for easier breathing and prevents irritation. Our new, subtle designs feature translucent pullers that complement any wardrobe and style. Available in 0-6 months and 6-18 months sizes.
