The Lolly Nenny Keys Teether helps in the initial phase of teething, as it relieves the discomfort and itching in the baby’s gums caused during the birth of the teeths. The keys amuse the baby and the carabiner makes it comfortable for the baby to hold it, in addition to having an opening that allows you to fit it in different places, such as bags and strollers. Indicated by pediatric dentists, biters also help oral hygiene and stimulate the movement of the bite.
