Nursing Necklace, Mother's Necklace, Chewelry.
Teething necklaces help infants and toddlers when their teeth are pushing through their gums and they want to chew on everything. It's also helpful when they want to keep throwing it on the floor because it doesn't leave the adults neck.
Nursing necklaces help the infant grab onto the necklace instead of scratching up Mama's chest or pulling her hair.
