Nuby's chillable teething rings are a fun and interactive teether toy for babies ages 3 months and older. These teething toys are made of soft materials for tender mouths and provide teething relief without being rough on delicate gums. These clever cooling teethers use purICE gel to help soothe and calm fussy babies. The purICE gel filling stays cooler for longer than water-filled teethers. Pop the IcyBite Teethers in the fridge to chill, then let your little one nibble and teethe their way to relief. For additional soothing, this Nuby teether's multi-textured surfaces massage and stimulate baby's sore gums. The varied teether sizes and ring design allow little hands to find the best fit for their grip and help support tactile development, while bright colors, fun shapes, and interesting textures appeal to your little one's sense of sight and touch.
