Tired but not bad

Little Prince and I didn't sleep at all last night.  He finally went to sleep at about 5 a.m. So I was worried that he would be hard to get along with during his therapy today.  But he had a great time.  He was so happy!  He loved the ball pit and couldn't get enough of the bean bag  chairs.  He was so sweet!  He was on top of the world until we had to leave.  Then he screamed for about 20 minutes.  He did not want to leave!  I am blaming his upset on his lack of sleep.
