Nolan has just really begun to play with things they way they are intended- he pushes cars and trucks around making vrrrrrmmm sounds. He is trying to sort shapes and stack blocks. It's really fun to watch him play. And then he finds a box. He carries the box, more than half his size, around the house finally setting it down on all the books he's pulled off the shelves. He bangs on the box, sits on it, slides down it and then climbs into it.
