NUK® nurtures best. That is why over 55 years ago a doctor and a dentist invented the first NUK® pacifier to mimic the natural shape of mom’s nipple during breastfeeding. What they found was the baby’s tongue compresses the nipple against the roof of the baby’s mouth allowing the jaw to move naturally. Our asymmetrical shape is unique to most other pacifiers that don’t have a top and bottom, because NUK believes this is the best shape that allows your child to gently exercise their tongue, palate and jaw, which encourages the proper development of your child’s teeth. Our heart shape shield fits perfectly on baby’s face allowing the nose to be unobstructed and good air circulation around the face while being used by your baby. Our Elephants & Butterflies designs are trendy and adorable. Look for our matching orthodontic bottles and silicone spout learner cups.
