Nest the blocks, build a tower, and take shape-sorting fun to new heights! These multifunctional blocks have something new to explore on every side: a family of faces, drop-through tops, shape-sorter sides, and a school of sea creatures offer lots to discuss as children build vocabulary, hand-eye coordination, and motor skills. The sturdy plastic materials and contoured rims make it easier for little ones to place each block, building confidence along with coordination and balance. Creative cutouts in the cups and lid and a collection of shape pieces add to the fun, letting kids create their own shape-sorting activity—or build a tower and drop the shapes all the way through! A felt flap in the base provides sensory reinforcement as children reach in to retrieve the pieces, encouraging little hands to keep exploring, discovering, and learning with this exciting baby and toddler toy. Melissa and Doug K's Kids toys nurture early childhood development in three key skill areas: physical, cognitive, and social. With interactive designs and multisensory features, K's Kids promotes constructive play and effortless learning, keeping interest high and new skills flourishing throughout the baby and toddler years!
