I'm a regular listener, but usually only lurk on this board but I have to chime in on the shoe size issue. Not meaning to scare you Julie, but when I got pregnant with DD I wore a size 7 1/2. Well, I just recently decided to start running again and went to get my feet sized. I am now the proud owner of a pair of size 9 1/2 NB(also known as sled runners

)!!!!

I told the cute little sales guy "No wonder my feet hurt every time I run."
Mandy, about the belly cast advice I need to give a warning if anyone decides to do it. We decided to do one when I was pregnant and did it in the basement so as not to make a mess upstairs. I sat in the chair so long that when I stood up,
I immediately passed out and fell straight forward on my belly on a concrete floor. The baby was fine but I did have to go in to have everything checked out. Now, I'm not too sure DH ever recovered from having to lift my gargantuan body up off the dirty floor-LOL. So, I guess if you do it just try to move around a little during the process.
Anyway, back on topic here. Good luck with the childbirth, Julie, and don't worry about cleaning house, etc. because..... Pay attention now, this is very important...YOUR HOUSE WILL NEVER BE CLEAN AGAIN!!!!!!
