Oops, sorry, didn't read all the other posts, and apparently you have already had the above refrain repeated for several pages...my bad
I sincerely hope you get lucky and have no problems. It sounds like you are treating the situation as well as you can and trying to prepare for anything that may occur...I'm sure that as you run into things you can find most answers here on the forum.
Good luck to you and your new addition!
