The nursing necklace is used to encourage baby to grasp it rather than your hair or another part of your face. When babies have teething pain they can get angry because of the pain and will try to bite something to soothe it. That’s one purpose of the teething ring. Rather than bite the bottle teat or your nipple if you are breastfeeding, your baby can grasp and manipulate the necklace while they are feeding. You and Baby can be comfortable and appreciate this moment together.
