Now you see him, now you don't. There is no hiding from this trend! Camouflage Pacifiers will help your little one stand out with colorful camo designs for boys. NUK® orthodontic pacifiers are designed to be just like mom. With a natural shape that mimics the form of a mother's nipple during breastfeeding, they encourage healthy oral development. All NUK® orthodontic pacifiers gently exercise the tongue, palate and jaw as well as promote proper teeth alignment. The grooves in the pacifier shield allow air to circulate, preventing skin irritation. And of course all pacifiers are BPA free.
