I have two boys and that's fine with me. Dh wanted a girl, but not enough to let me have 3 children.
I would be happy with 3 (or 4 ) boys, but that's just me and perhaps after TTC for so long i was just thrilled to have children.
I don't know what it's like to have a girl and probably never will, but i don't feel any sadness at all about that.

We're all different and have different 'pictures' of how we see our family. I think 2 boys is great - for me. It's ok if it's not for everyone.
