This silly teether is ideal for tender-gummed teething babies. The Nuby Silicone Teether is made of soft silicone that soothes sensitive gums as babies teethe. It’s designed with multiple teething surfaces, including small Nub-eez that gently massage and stimulate gums. Each teether is designed with small openings that are easy for baby to grasp & hold. Ultra-flexible silicone is twistable, squeezable & tuggable. Little hands will build hand strength and develop motor skills as they tug & twist the teether.
