There are females who are basically children who have babies, so I don't see what is so outrageous about an older woman having a baby.
I think a couple who want a child are much more favorable as parents opposed to an immature teenager having an unplanned pregnancy.
Yeh, she will be
very old. She may even die before the child hits his/her teen years; but plenty of parents die when their children are young and the children survive it.
