before we married, we talked about having only one child. so this might be it for us. I was raised as an only, and some of my bestfriends are only children, so I'm comfortable with the idea. We won't do anything permanent for a few years in case we change our minds.
btw on the topic of amalgam fillings, I was in the process of having mine replaced, and had one removed/replaced the cycle before I got pregnant. Would you be worried about it?
