Having a difficult time finding the right pacifier for your baby The new NUK pacifiers are accepted by 95% of babies* and feature the improved orthodontic nipple shape. NUKs asymmetrical nipple naturally fits babys palate and is now improved to allow for more room for a natural sucking motion, reduce pressure on teeth and jaw, and helps prevent teeth misalignment. Invented over 60 years ago by pediatric dentists and doctors, the NUK pacifier is modeled after the natural shape of moms nipple while breastfeeding. This makes for an easy transition from breast to pacifier and back. The NUK heart-shaped shield fits perfectly under babys nose for easier breathing and prevents irritation. With super-cute designs, this pack of 2 orthodontic pacifiers is ideal for your child aged 18-36 months. (*Based on Market Research, 2017, tested with 307 pacifier users)
