Hi Chatty, sorry you're so down about this. I can't really comment as I'm having my first, but I'm sure your boys will adore you and you'll always have a great relationship with them. As others have said not all mother/daughter relationships are like best friends. My sister and mum are a bit too similar and they clash soooo much, and my MIL and SIL don't even speak anymore.
I've got a friend who's one of three boys (well he's 35! Not really a boy) and I always used to say that I felt really sorry for his mum, but he's got a great relationship with his mum, he speaks to her at least three times a week (and it's not just because he's a mummy's boy, his brothers are the same) they absolutely dote on their mother. In fact, most men find it really difficult to find a women in life they love more than their mothers, I'm sure that's why so many find it hard to commit in relationships!
Another friend who's got two of each (she's very smug about that - the cow!) says her boys are much more affectionate with her, her girls (aged 13 and 6) are so independent and headstrong, and her boys (12 and 10) are just the sweetest cuddliest little boys, when she drops them off at school the girls run off with barely a backward glance, and her boys always want a kiss from mummy!
I'm sure everything will be fabulous with your boy, he'll be adorable and worship the ground you walk on. I'm really hoping for a boy, I'm terrified of having a girl. If she's anything like me she's going to put me through hell!
