The bright colors and fun fruit shapes of the Infantino Sensory Stacking Rings are a twist on the traditional stacker rings that will keep your baby engaged for hours of open-ended play. This set has 6 toys that can be stacked or each toy can be used individually: 1.) pineapple selfie mirror with crinkle leaves teaches self-awareness through peek & see play; 2.) lemon teether ring provides a strong, yet soft biting surface, plus fiddle flags, crinkle leaf, and a sliding bead for cause & effect movement; 3.) wavy ring adds multi-sensory textures in a fun shape; 4.) grape water-filled teether offers a soft biting surface than can be chilled in the refrigerator for extra soothing; 5.) avocado rattle teether soothes sore gums and delights with visible rattle beads; and 6.) wobbly watermelon base with cheerful chime. This set will awaken your baby’s senses and encourage cognitive and fine motor skill development. Teethers are BPA-free for safe chewing.
