When I have a 'silly' child, a 'screwing around' parent, or the last child of the day this is what I do. I get the childs shoes/boots and sweater on, grab the jacket and sit on the carpeted area that is near the front door. We sing silly songs, do flash cards, point to body parts (all depends on the age of the child) and when that door bell rings, I stand up, unlock the door, open it, walk back to the child and put the jacket on while discussing the childs day. The children all know (even my youngest daycare children) that they are NOT allowed to cross the line to the carpeted area with their boots on, so this prevents them from running away and starting a high speed (and tiring) chase.
