One of them had her first child about 5 weeks ago after several rounds of in vitro and a very difficult pregnancy. Unfortunately, because I don't know these people very well and because I am quite an introvert (a great listener but not always the most engaging conversationalist), I had trouble keeping the discussions from constantly cycling back to babies and parenthood... and of course the dreaded question, "When are you going to have yours?"
This is one of those Moms that you might want to give a break to, though.
I had a friend who had to go the invitro route - and it was a painful, stressful journey for her and her husband. They went through 2 miscarriages, 2 missed implantations, and then she was on bedrest for her entire 3rd trimester.
So these Moms are not only the normal "happy to have a new baby" bubbly, but experiencing a level of relief that everything is over with and came out OK - most of us (even those of us with kids) can't even relate.
I am sorry that it eventually came around to the "so when are you..?" I think that most people don't know what else TO ask. They want to include you in the conversation, and are not sure how to.
Actually - this gives me an idea for another conversation - so I'm going to go start a thread about this very thing.
