Then it assumes that we're too weak and selfish to handle the common discomforts of pregnancy. I have easy-to-medium-cruddy pregnancies, but I have friends with just as many children who have disastrous health problems during pregnancy, but still carry their babies to term, because they want their children.
Yes, sometimes there are reasons which absolutely necessitate an early delivery. Some babies are early because of natural premature delivery. And the survival of premature babies in the 25-30 week range is iffy. The point is that the intention in those situations is to keep both the mother and baby alive.
I don't get the motivation of the judges who rule "kill any baby, any reason, any time." The women are all too old for it to have any personal relevance. The men ... well, God is their judge. I just don't know what's wrong with these people.
I'll be delighted to have this pregnancy over with ... when I hold my living baby. I know, from two miscarriages of my own, and my friends' experiences, that we can't count on pregnancy's resulting in a living child.
