How does he sleep like that?

One of our favorite things to do when we go to bed is to sneak into Alec's room.  Inevitably he is upside down or off the bed or in some strange contorted arrangement that in my opinion is not condusive to sleep.  This picture was taken in the dark, and came out okay.  It's not uncommon for him to be off the bed entirely with just his head or foot on the mattress.  Crazy kid.
