So tired I'm delirious

I am TIRED.... no, that doesn't describe it. I am so tired I am delirious.

Between the two kids being up last night, I think I slept a total of about 90 minutes. I am a walking zombie.Tell me two things:

1. If you rolled over and got your arm stuck underneath you EVERY TIME, wouldn't you, at some point (say after the 15th TIME!!!!), decide not to roll over again until,..... maybe.... the MORNING!

2. Why is 4:30 am a good time to wake up and want to play with playdoh?
