I was actually thinking about this the other day. At our wedding he definitely teared up until I made him burst out laughing when I got up there - I managed somehow to make it so just as the music ended he was uncontrollably laughing and everyone was looking pretty confused. To this day people ask me what I said to him.
For the baby - I'm not entirely sure how he'll react. I know he's not nervous about blood or anything. I've never seen him get queasy over seeing anything. I mean after all, he is a horror illustrator and the things he draws are tame to whatever might happen during labor I sure hope. I'm not entirely sure the baby is real to him yet. We discuss bug a lot, we have seen bug and heard the heartbeat...but until the baby kicks him or is physically here it's still a far off dream to him almost. It's hard to desribe. So I'm not sure if he'll cry or not. I know he'll definitely be stunned for a minute or two when the realization hits that it's not just us anymore. Everyone tells me that when it's finally just the three of you in that room you realize how much life has changed....I'll expect to see his emotion moreso then.
