Having raised a few I wish now I might have had one or two more. However, at the is point in my life (and for the rest of it) no way. While I might enjoy being pregnant I've gone through the end of that twice with my wife, once with a close friend, and that last little bit is not easy, so pregnant yes, give birth, more than likely no - and give up another 20+ years of my life, I don't have that to give anymore. Though I do look forward to grandkids (BUT NO RUSH THERE BOYS!!! so don't go out just to make me a grandma).
As to it being a right. Wow, that's loaded. That we license people to drive mo-peds, or to be electricians, but not to be parents creates social problems beyond all other social problems. And I'm sure I'm not alone in thinking that the best parents I've ever seen didn't have enough kids, and the worst had too many. Some of the women I know, the majority at that, found it the best thing they ever did, but I know more than one who thinks that it was the worst mistake they ever made (at least at the time they made it, and the person they made it with).
