Yesterday, I was poking at the place I thought the baby was hanging out trying to get it to kick for Mark. Mark was getting upset because he thought I was poking the baby and irritating him/her. I just assumed it would move out of the way if it were irritated. We began talking about all of things we don't know about pregnancy. Such as: how does the baby move? DOes it float there like a helium balloon? Do they kick and move like an astronaut? I realize I should know this, but well, I don't exactly.
