Guys, What are subtle signs guy or yourself make to a girl hinting at future kids?

This guy I like and I know likes me ( but is conflicted at times ) when I sometimes talk to him he’ll mention kids and I can’t tell if he’s hinting at it or what, what are some signs? here's a convo.
( H is 🙋🏻‍♂️. M is 🙋🏻‍♀️… him and Me )

H: I will never raise a child out there.

M: Nope me neither, I’d shelter my kid

H: Me too till they can't stand me

M: Protect it be a good mom. Which people say lol. You’d be a good mom
I mean yeah but do see how really messed up the world is.

H:I would be a good mom huh

( then I joked about him being a good housewife, and he’s watching the kid and that I see myself having a dog )

H: They're great

M: But if I decide on a kid it better be one and a girl. But I don’t get a choice. Why we taking about kids lol.

H: I want a son, it's only in my nature you must understand. I don't know we just got here.
