Sometimes it's good to suck, did you know there are two ways to suck? Nutritive sucking happens when your baby is feeding. Non-nutritive sucking happens when your baby is trying to self-soothe. Developed by a pediatric dentist, the jewel pacifier's design keeps self-soothing in mind. The gem-shaped nipple of this pacifier encourages tiny tongues to stay in the proper place, and the flared-out shield allows the baby's jaw to move freely for a comfier suck. If you are looking for a one-of-a-kind, the jewel is a true gem.
