TTC Talk with Fiancé

My fiancé and I have been together going on 10 years. We committed our lives to each other a long time ago, and finally made it socially official in December. We've discussed the idea of having kids before the wedding, & we're both okay with it. I've been off BC since November. We're not-trying-but-not-preventing. He knows I don't have any protection, and he doesn't provide any either.

Lately, I've been getting baby fever, bad. I don't even call it baby fever anymore, because I've realized that I'm just ready. If I didn't think it was the right time or that it wouldn't work having a baby or if I had any negatives thoughts about the idea, I would be making sure it couldn't happen. But I am genuinely ready for this (or as ready as one can be without a six-figure salary). My struggle is how to officially have that conversation with him, and going from "not stopping it from happening" to "let's actually make this happen". I think with all guys, he's just scared about what it would mean and the added respectability and all that. I know he can do it, I just need him to believe that.

Can anyone give me any advice or pointers about how they had this conversation with their SO or how to boost his confidence?
