Were do we draw then line...when do you know that your last baby IS your last baby?
I would like to know the answer to that myself. Sam was our last. Then Harry was our last. Now this bub is going to be our last.

While there are ways to make sure of that, I think that for me, losing that ability would be completely unbearable. DH does not want me to have to go through what is major surgery, either. He actually thinks its horrifically unfair that the government will pay for a woman to go through all kinds of surgery as birth control, but a vasectomy - which is safer, more effective, keyhole day surgery with a shorter, less traumatic recovery time - we have to pay for that. He is not happy about it at all.

Even then, when we were ready to pay for it, he backed out because he wasn't sure he was ready to let go of the idea of another baby. That was just after Sam. If he had, we wouldn't have little Harry and its impossible to think of life without him now. To not keep going, DH and I will both be fighting extremely strong maternal/paternal urges. I don't doubt it is going to be a very long road.
