i wonder what it's like in there...

Are they squished?  Doc says they have lots of fluid and Baby A rotated so that both are now standing up, so there must at least be some room.

Do they sleep? 

How does that whole breathing in liquid thing work?  Is it like in the Abyss?

Can they tell when I'm happy, sad, stressed, etc.?

What's it like when I sneeze?  Whoooooaaaaaaa, what was that?!
