Hi M.,
I understand your want for another child, but perhaps your husband is right. Our earth is over populated and in my humble opinion, you have every right to replace yourself. If you have two beautiful and wonderful children, I say, stop while your ahead.
Are you willing to adopt? Maybe if you want another child so terribly, you have what it takes to adopt a toddler or older child. These children are here already and not wanted by their parents. How awful is that.
I was told that I would never have children. 10 years later, I was pregnant. I immediately told my husband that he needed a vasectomy. I am unbelievably happy that i had my daughter safe and healthy, yet I still know that there are children in the world who need me and you. They need us because we both have that innate sense of motherhood that will benefit them and ourselves and our children. We will feel fulfilled by mothering another child, the child will be overjoyed to be loved and our children will see the magic that we all offer the world by opening our hearts and homes.
Just something to think about. Maybe your husband would take to that idea better.
Our toddler will be with us in a little over one year.
good luck.
P.
