MissMummy I had the exact same issue, but everyone I know who is a teacher has gone for slightly old fashioned names so definitely not ones for the kids we teach - think Ivy, Hattie, Eleanor etc. Come to think of it, we've all had girls. Weird!!!
I find the whole thing about gender fascinating. There was a preg thread about someone being disappointed to be having a boy & so many comments were relating to gender cliches. It made me examine how I feel about gender & try to recall how I felt during my DD's pg. We didn't find out until she was born, so there was no picturing a particular sex/baby in my arms. I guess it was all a bit abstract for me - I'm not really much of a baby person. So by the time she was born, I hadn't got any pre-conceived ideas about what she'd be like or what I would do with her as it were. I mean, she is not a girly girl, she's a tad scruffy & a bit rough & tumble and her favourite DVD at the mo is Toy Story. She isn't quiet or demure or any other girl cliche but then nor am I. I do wonder if, because in my job I see lots of different types of boys & girls, I don't generalize about how girls & boys will be. I mean, there are gentle boys & hard girls... They're all different. Boys often play with guns & girls tend to go for dollies & tea sets, but my nephew plays with a kitchen set & boys at toddler group push the buggies!! I suppose my Dad isn't your usual 'bloke' either so perhaps I didn't have the usual perspective there either?
Anyway, either way, we're not finding out & I'm struggling to imagine having 1 or the other. I kind of hope its a boy, as I have a girl, but equally, can't change it, so happy with a girl. It'll be one or the other though!! 
So congratulations Evil you will love your little baby, boy or otherwise, and you will get to know his little foibles & personality traits and you'll forget you ever wondered what you'd teach him :)
