Stretching

I've discovered my first stretch marks on my tummy. I know, at 37 weeks, I should have some stretch marks. It just kinda took me my surprize, now I'm obsessed with rubbing cocoa butter on them to make them "go away"-which I know won't actually happen.
Speaking of stretching, is it possible for a baby to push herself out of the womb? I swear, Cali likes to get her little feet up under my ribs and stretch her legs out as far as she possibly can. She's so strong! Sean says she's going to torpedo herself out and that I won't have to do any pushing when the time comes. I wonder if he's right...
No pictures to post of The Steamroller, unfortunately. I got them, but she was being a booger again. I think she's a boxer, because she keeps her fists right up by her face whenever I get an ultrasound. Must be a kickboxer because she constantly is kicking during the ultrasounds as well.
I got the fabric I'm going to make Cali's bedding out of yesterday. Now I just need Sean to get my sewing machine down and I'll start putting it together. There's still so much that needs to be done before she comes, but sewing her bedding shouldn't take me too long. It's going to be super cute, so that's gonna be fun to see it all put together. :)
Has anyone read "The Baby Book" by Dr. Sears? I just bought it yesterday and it's seriously taking a lot of the anxiety away. I feel better just knowing that I have some sort of "instruction manual" I can turn to when I start thinking I'm screwing things up too much. I know that there's no way I can really "prepare" for her coming, but I'm trying to get as much information as I can to save me from having an anxiety attack or getting an ulcer.
My feet are swollen, I feel like a walking ball, my wedding rings can't come off, and I waddle worse than a duck. How's life treating you? :)
