I know deep down that I care more about my mum's relationship with my DS's than I do about my MIL's. Because she's my mum. However, I do like my MIL a lot, and try to involve her as much as possible with the boys. That said, I'd never have wanted her there at the births (my mum was), or in the v.early days when I felt really rubbish. I feel sad that I will probably never have this close relationship with the mother of my grandchildren. That I will always have to be very careful of everything that I say and do for risk of offending future DIL's. However, both of my DS's have problems with their testicles, so at the moment, I'd just be thankful to know that they can both have children, never mind what my relationship with them will be.
I love being a mother of boys, which I find strange since I never would have 'chosen' to have boys, certainly not two anyway. I think I'd have always longed for one if I just had DD's as DH is a very good father of boys. However, I no longer long for a little girl, I'm only sad for the loss of the relationship that I might have had with a daughter in the future. But, I might not have gotten that anyway for some reason, so I'm not going to spend my whole life sad for something that I haven't got.
I know that I don't want three children, so we won't try again for a girl. If I knew that I wanted a third, be it boy or girl, I probably would try again, but I don't really want any more children, I would just like a little girl.
