In a kinda similar boat, though less "trying to convince" and more "trying to decide if we want a kid". (Because really, the boat for multiple kids for us has sailed.) My wife's five years younger, but we only met three years ago, so it feels like we've been speed-running our relationship while simultaneously dealing with life and career stuff.

I live across the country from my nephew, but if I end up not having kids, he can look forward to notably more visits and funtime with the uncle.
