The Nuby Silicone Teether is made of soft silicone that soothes sensitive gums as babies teethe. It is designed with multiple teething surfaces, including small Nub-eez that gently massage and stimulate baby's gums. Each teether is designed with small openings that are easy for little ones to grasp and hold. The ultra-flexible silicone is twistable, squeezable, and tuggable. Little hands will build hand strength and develop motor skills as they tug and twist the silicone teether. The bright color and fun shape of the teether will catch your little one’s eye, keeping them engaged and entertained.
