You're not wrong NanaNina but what I was trying to say is that once you start saying who can and can't have babies you start straying into increasingly dodgy territory. There are things to be said for a sensible older woman having a child, despite the obvious risks in comparision to women with mental health problems, drug problems, in abusive relationships etc.
It would be great if all kids were born into happy, stable homes with mothers who would see them through to their adulthood. Unfortunately life isn't like that. I just think it's unfair that older women get called selfish for wanting a child when age can be a less difficult factor in comparision to some of the things I mentioned.
I don't necessarily think it's right that they are having kids in their 60s, just that to me, it's no worse than some crack addicted woman having a stream of kids who end up in care, or worse.
