I spend my whole day putting the blocks over in one area, the books on the couch, the cars on the parking garage, the dolls in the buggy, the dishes in the shopping cart and so on and so on. Sometimes when I get way too busy with things I freak out a bit and tell the children it's cleanup time NOW, but usually I'm just running around organizing bit by bit as they play. Seriously, they have the attention span of gnats!
