Gosh, that's a hard one. I have been blessed wth one of each, so it's not exactly as though I am lacking one or the other. I know my sister would love to predetermine a girl because she has three boys and has always wanted a girl. I kind of think that I would like the opportunity to choose, because at times, I can be a bit of a control freak and there are already so many things about pregnacny that are out of our control. The real problem would be deciding which sex to choose because I have enjoyed raising both!
