Seriously soothing teether for gums - with the added bonus of the patented “pop” technology for busy hands. Two uses: 3+ months as a teether for soothing sore gums, and 12+ months as a toy for bubble popping play. Responsive bubbles encourage fine motor skill development and hand-eye coordination. Hollow bubbles are easy for baby to grab & hold on to. Dishwasher safe. Refrigerating or freezing is optional (it’s effective at room temperature, too). 100% silicone. No lead, PVC, BPA, latex or phthalates. Playful micro-textures massage sore gums (and entertain fingers).
