Roll into a happy tactile-learning adventure with the Lamaze Stack Rattle & Roll Blocks. This set of rattling blocks is designed for easy stacking, and features an elephant roller that little ones will love. The Stack Rattle & Roll Blocks encourage fine motor skills, hand-eye coordination, and exploration as little ones stack the cubes onto the elephant roller and onto each other. Each textured cube has a ball inside that rattles, adding another level of fun and discovery. Plus, the weight of the balls aligns the cubes and holds them in place, so there's no more frustration or tears. Just easy stacking that encourages little ones to keep exploring and keep discovering!
