I know that because of SS and BM, DH had set in his mind he either did not want any more kids or wanted to wait a very long time to have another. I didn't like that idea, I wanted to be a bio mother. We eventually decided to try for a baby, and three years later we got DD. DH and I have talked about more. We are for sure going to try for another. If it is a boy, DH wants to stop but he won't rule out a third child for us, but he is comfortable with two. If the next one is a girl, he said we are definately trying one more time.
Does your husband know how many kids he wants? Is he done? Or does he want more?
