Ok, so that is actually an air mattress propped up against the wall that he is climbing! It was left out after my parents stayed with us and I turned around to see him all the way at the top of the mattress! Oh, the things a toddler will to do to entertain himself. Of course, to him it was not an air mattress but a climbing wall and slide all-in-one! Lay it on the floor and it’s a trampoline! How’s that for cheap entertainment?!
