Your baby can shake, stack, sort, and keep playtime rolling with the Fisher-Price Pull-Along Activity Blocks. Each of the 9 chunky blocks features colorful, textured artwork of familiar objects, shapes and letters, as well as a number to help tiny match-makers sort the blocks into their corresponding spots in the cart. For more exciting sit-at play, your baby can shake the rattle block to see the colorful beads rattle around inside. When your toddler is ready to walk, they can take the whole stacking party to-go by pulling the wagon along! Where development comes into play. Fine Motor Skills: Grasping and stacking the blocks helps strengthen your baby's dexterity and hand-eye coordination. Gross Motor Skills: Little muscles get a big workout as your toddler pulls the wagon along as they walk here, there, and everywhere. Sensory: Each of the blocks has different colors and textures to excite and delight your baby's developing visual and tactile senses.
