If I had had kids just for the sake of it, because society wanted me to, I don't think that would have been fair on the child. I might even have resented them. You have to want to be a mum to be a good one I think. As I am not maternal (am towards animals, funnily enough) I don't think it was selfish, I think it was fair. If people think that women who don't have kids are 'not really women' then perhaps they have low IQs because they obviously haven't thought it through properly. And with the planet as it is it is anything but selfish to not want more people to suffer.

In this day and age it probably is the smart thing to do to not have kids, with the way things are.
