It shouldn’t be hard really, should it?
I mean, aside from having 9 months to think up a name, you must have vaguely thought about it beforehand. “If I had a baby girl I want to call her Emily”.
But it’s not that easy is it?
Not only have you got to run it by the other person who helped produce the child (although I do think the months of actual pregnancy should give the mother some special privileges, no?), but every Tom, Dick and Harry sticks their ore in too. “Na, I knew an Emily at school. Total. Bitch.”
