Even if I were that flexible ...

I wouldn't sleep like this. I mean seriously.

The funny thing about this is that once a night lately he's started screaming and when we run in there, he's standing up crying because he can't figure out how to sit down. Here, he clearly fell asleep sitting up either because he couldn't figure out how to get lying down or because he couldn't bother to do so. And fell asleep. How many days would it be before you could move again if you slept like this all night?
