My son loves his Nuby Ice Gel Teether Keys! We've had them for a few months now and they've been wonderful. He's able to hold onto them easily and they've helped with the eruption of his front, middle and back teeth. The purICE technology provides gentle cooling on his gums which has been a lifesaver during teething. I would highly recommend this product to any parents who are looking for a teether for their little one.
