Nuby™ IcyBite™ teething keys are the Practical Parenting 2009/2010 Bronze Award Winner for Best Toy 6-18 months. The teether is ideal when front teeth first start to show. It contains non toxic purIce gel that allows the teether to stay cooler longer than water filled teethers. The cool textured surfaces soothe and stimulate sore gums safely. The teething nubs help massage tender gums. The bright colourful shapes stimulate your baby visually; and help with hand eye coordination.
