MummyW good luck today with your scan. I second (third etc) what everyone else has already said - particularly Loopy's eloquent words above - there is definitely no need not to talk about what you're feeling just because this isn't a MC thread.
loopy I expect if your DH isn't talking about it he's just working his way through it in his own time and will come out the other side in due course (and in plenty of time for Christmas - how wise to get your scan when you did) perfectly content with the state of the nation... Let's face it, men are generally not great at talking about things that bother them and are often better left to their own processes!
kiwi the little girls I know are all much more feisty and independent than the boys, who are generally very affectionate and sweet (though it may well all go wrong when they go to school 
). I think you're right too that they love the baby they get whatever (as indeed will I).
My DH's theory is that most people generally want to recreate themselves and have a child of their own sex they feel they will be able to identify with - hence my wish for a little girl and the fact that, having got one DS already, he doesn't care this time round! Though I'm actually becoming more of the view that I don't care nearly as much as I thought I did. Although yesterday a pregnant friend with a DS pointed out to me that if we have two DS' (bearing in mind neither of us want 3 DCs) we'll never be the mother of the bride!
Cowboy it's not surprising you're missing your dad - two years is no time at all and Christmas is an emotional time of the year even without the timing of your loss - factor in the pregnancy hormones and the extra emotions that brings, it's obviously going to be a tough time. But lovely that you and your mum are getting closer.
There is definitely something about being pregnant that makes you appreciate your mother more. I was supposed to be adopted after birth (my mum was accidentally pregnant at 18 and single in 1974 and it was the done thing) - in the end, she was impressively strong enough to defy convention and bring me up on her own, but being pregnant last time with DS really brought it home to me what it must have been like to go through an entire pregnancy and birth not expecting to keep your child. I remember being really upset on her behalf last time when she admitted to being envious of me going to choose baby things and newborn clothes, because she'd never done that
