Sweet, happy boy playing while mommy eats breakfast.
Giggling before bedtime.
Turning in a circle. He can do it faster than this if he really wants to turn, but he normally just works his way around playing with toys in a circle. Usually he starts playing sitting up, then leans over, then decides tummy is the way to play. This is at the end of his 'tummy playing', so he's getting frustrated and is getting hungry, I think.
