I'm about to get married and my fiance and I have not talked about having children. I worry about starting this conversation with him - I want many babies and he seems disinterested! How should I do this?

Go and ask. There should be no fear for an open-discussion in a good relationship. Either both of you agree to have a kid, agree on when you both are fine to have a kid, or agree that you won't have a kid in the next decade. #Upfront
