Well, since I think I'm probably the only person here who has copped to wanting a daughter when I've only had sons, I'll say this, Terza: so what if they didn't turn out like I hoped? Not a big deal to me. Children have a way of defying whatever expectations you might have of them, for good or ill. I would have maybe a year or so to dress her up in a pretty dress or whatever, but she's still a person in her own right, and any attempts to "mold" her into whatever image I had of a girl would be a resounding failure. My father tried to treat me like the boy he wished I was, and while I was a tomboy for many years, ultimately, I've ended up pretty darn girly, as far as that goes.
So, while it makes people "ick" that I might desire to have a daughter (and might very well have chosen the gender of one of my children at the time, if I could have), I can also tell you it's about a lot more than just having a dolly to play dress up with, and I won't apologize for wishing that I had a daughter. Now, that doesn't mean that I wish away any of my boys, because I love them very much just the way they are. They're all very cool, unique people, and irreplaceable. But it would be nice to have a daughter in the mix, too. Funny that this thread actually makes me feel a lot more comfortable with the idea that I wanted that.
ETA: Also, I find it a bit appalling that people would be okay with selecting away for a disease, but not for sex or gender. So, I guess it would be perfectly okay with everyone if I had selected to abort my autistic son, but not if I had deliberately chosen to have a girl?
