Anything is possible with God. Besides if a woman takes good care of herself she can have kids later.
Downthread from where you are, I gave a more detailed reason for our current decision to not have children, at 320. I know for the people in this article, its an "us" versus "them" thing. It isn't that way for me at all, just might not be something we want to do. I don't bring an agenda to the thread, except, there are lots of ways to live in life.
