I think it's entirely understandable to wish for a girl, especially as a feminist.
We spend a lot of time griping about male privilege, male domination, how most wars and conflicts around the world are pretty much promulgated by men, how it's women who are oppressed and suffer.....then we give birth to miniature men!
Coming out of an abusive relationship (with a man!), and facing pregnancy and parenthood on my own, I was devastated to learn I was expecting a boy. I had had visions of raising a strong, warrior girl- and now I had to completely revise my expectations.
We just have to look ahead to the teenage years and unpick the messages that we are supposed to be giving our children. We should be raising girls to be strong enough to resist all the shit that gets thrown at them by boys/ men. We should be raising boys to respect and not give shit to girls. This is good, but at the core of it is a message that is, I'm afraid, largely true: as a default position, men are the shit givers.
I love my little boy....so much so that when I got pregnant again I wasn't half as upset to discover that I was expecting another boy. They are both lovely, but I feel that I bear a heavier responsibility than if I had a girl: I must raise them to be unlike the majority of men.
(Plus, y'know, all those pretty dresses I'll never get to buy
)
