Nuby’s BPA FREE IcyBite teething keys are ideal for when front teeth first start to show. When placed in the refrigerator the purICE Gel allows the teether to stay cooler for longer. The cool textured surfaces soothe and stimulate sore gums safely. The teething nubs help massage tender gums. The bright colorful shapes stimulate your baby visually and help with hand eye coordination. Nuby’s IcyBIte Teether Keys are small in size but big in fun!
