Teething is smooth sailing with Nuby’s IcyBite Sea Teether. This clever cooling teether uses purICE gel to help soothe tender gums. The teether's purICE gel filling stays cooler longer than water-filled teethers, providing extended relief for sensitive gums. Pop the IcyBite Sea Teether in the fridge to chill out, then let your little one nibble and teethe their way to relief. For additional soothing, the teether's multi-textured surfaces massage and stimulate baby’s sore gums. The keyring design is easy for little hands to grasp and hold, which supports tactile development. The IcyBite Sea Teether features fun sea characters to draw little eyes and keep baby’s attention. For parent's peace of mind, the IcyBite Sea Teether is BPA-free.
