I have two grown children and seriously would have loved to have had many more. I didn't because my first husband was set on only two, my finances aren't stellar and I'm concerned about overpopulation. I married my second husband when I was 40 and felt the risks at that age were too high, plus that pesky cost issue. We need to be clear on a few things. The world would be better off with a population probably half as large as it is now. The ideal way to reach that goal is for nobody to have babies unless they really, truly want them. Accidental pregnancies should be rare. We have reliable birth control and we should make it available to every person who wants it, no questions asked. If only the people who earnestly want children had them, the world's population would be much smaller. People like me would ideally be able to afford to have three or four kids, while plenty of other women would have none at all. Most pregnancies are not planned. That's ridiculous when we have reliable contraception available.
