Have any of you totally disagreed with your SOs about how many children? What happened? How did you decide? If you wanted more, and he wanted less, how do you ultimately feel about it?

DH and I have three lovely children, but I would love one more. Just one! (I know you think I'm nuts) I want a big family and I've always wanted a big family, but he isn't on board. He was for awhile (like in October!) but isn't so sure anymore. I'm trying to mentally prepare myself for no more kids, but I don't know if I feel ok with it. Will I ever?

What are your experiences?
