The disappearing Leo

I have always prided myself on the fact that I can leave Amelia and Leo alone in a room with confidence that nothing will happen. Now that Leo is a mover and a shaker, I can't leave him anywhere unless I want to come back to find him across the room, under the table, sucking on a dirty something or other. These pictures were taken one after the other, Amelia was singing "Twinkle Twinkle, Little Star" and reading her book while Leo was grooving across the family room floor.
