6 months & up. With vibrant colors and soft textures, each toy builds fine motor, coordination, sensory exploration and cognitive skills. Toys feature dimples to push and pop, shapes to slide into place for shape-matching play, spinners that cascade up and down, and textured spheres with squishy features that slide back and forth. This Fine Motor Skill Building Set encourages cause-and-effect learning, shape recognition, reaching and grasping, pushing and pulling, and more!
