Once Small Fry FINALLY falls asleep, he goes into a deep, deep sleep that lasts until just before dawn. After that his sleep becomes lighter and he's easily stirred.
Because of the way our house is arranged, you can hear the shower, though faint, from Small Fry's room, and it often wakes him up. I can't tell you how many mornings Small Fry has come to the bathroom door while I'm in the shower, and, with his blanket and pig, plops down on the floor and goes back to sleep.
I'll be so sad when he stops sleeping with his knees curled up under him, whether he's in his bed or on the floor.
