I wanted three children and I have three boys. They are a gorgeous bunch of mummy's boys and there's something lovely about them all being boys - somehow they can really connect over those dinosaurs/spidermen/whatever, in a way that I can't quite imagine if they were a mixed bunch.
BUT, I really wanted a girl, and always assumed I'd have one. It wasn't an issue 1st time round, and 2nd time I was sort of pleased to have ds2 as I knew it would otherwise have been an uphill struggle to convince dh for number 3. But then I was devastated when I found out the sex of ds3, really didn't bond properly for ages, and I guess suffered pnd for most of the first year. I feel that it would all have been a happy time if he'd been the girl I wanted (I know it's horrible, don't shoot me, I couldn't help it).
Anyway, now of course I wouldn't swap him for anything, ever, and I find being the mother of my sons wonderful. But I still feel that not having a daughter is my tragedy. I doubt that I will ever get over it. I think it's because I was expecting to relive so many magic moments of my life with her (like when my mum used to take me to the ballet, and having elaborate french plaits, and all that sort of thing). So I identify with lots of the posters here, who are delighted with their children, but still have regrets.
I don't think you can assume anything about how they'll behave as adults - my brother and dh are always on the phone to their mums, and I never get round to calling. I actually think I call my mil more often than my mum!
And, do you really like dinosaurs less than Winx Fairies?
