I only have one child, so take or leave my comments.
Having 2 young children is a blessing, but it can't leave much time to do anything for yourself, including having tight control that's important during pregnancy. Could you wait a while to have a third child?
I just had my first a little over two months ago. It was a fantastic pregnancy.
Getting back to what you said, I think that it sounds like you are more Con than Pro. I was always under the impression that you couldn't have more than two C-sections? My doctor told me if I were to have another he would then tie my tubes in the same surgery.
