Katie, I felt exactly the same when I was pregnant with my dd- at the time I would have been so disappointed if she was a boy. Now I desperately want a boy, because I want one of each and because we have a boy's name set but haven't a clue what we'll call it if it's a girl!
I don't remember having any dreams the first time round, and I haven't had any this time either. With dd I was steely sure it was a girl, from the very beginning. Even when the told me at the 20 week scan and 4D scan, I was just like "I know", lol. But this time, no clue, so that kinda puts paid to my theory of "you just know", lol.
Sorry, just realised my reply was f*ck all help, haha! x
