This lamp gave us a lovely opportunity to develop language.  The base is stationary but the layer with the seashells on the edge rotates!  This little guy parked his favorite trucks on the moveable layer and reached out with his index finger to spin his trucks.  Surely, not what the lamp maker intended but it provided a great opportunity to teach “park”, “touch”, and “spin” (and at a later time, “rotate”)!  One day, these little ones will thank us for providing the narration!
