When you say high rate of parenthood, are you referring to actual kids being born? Or the actual act of having and then raising the kids? My experience with a female narcissistic sociopath, was she was an incredible baby making machine and as of a couple of years ago she had 5 kids with 3 different men and takes care of none of them. No the fathers don't care for them either. But what can you expect when personality disorder teams up with Meth and that whole way of life. IMO it's a damn good thing she's not taking care of them.
