Rolling Rufus

Has anyone ever wondered how a tiny toddler can roll around in his crib, creating the most resonant, booming thuds and thumps, and sleep through it? It sounds as though he has knocked the crib over and he is pounding around on his floor, which is the ceiling above my head right now. Funny, because the juxtaposition of this excellent sleep ability is oddly contrasted with his inability to sleep through a door squeaking shut in a room across the hall. Ooh, I hope the new house doesn’t need WD-40’d! The smell lingers.
