Husband dropping a bomb

When we first got together my husband was pretty clear that he didn't really want any more kids since he already had 3 and I really did want (at least) 1 kid, but I wondered if I wanted to miss out of the love of my life for a kid I didn't yet have..

Anyways.. We're now 5 years later and after 2 years of ttc we've gotten pregnant and expecting our baby.

He saw that I really did want to be a mom and came to me with the idea of having one together ❤️

Anyways so the bomb he dropped on me today, when I'm 6 months pregnant, is that maybe he does want more kids, that he hadn't been ready to be a father before, but he feels more mentally in a good place to have kids and he wasn't mature enough to have them when he did with his ex and also how he sees a much better "mommy" in me than his ex, because she wants it all, a lot of kids and a big career and a lot of luxury and trips and free weekends and partying, and we don't actually want that for ourselves, I really just want to make the kids happy, his and my own.

I'm 15 years younger than him so it's definitely a possibility.. I'm just still wrapping my head around this..

We're now letting it rest until at least a few months after our baby is born which would give us a lot more information to make an educated decision about this. (since I've never given birth yet or taken care of newborn yet.. though I have taken care of young kids and older babies, so by the time our baby is like half a year in I'm "caught up" into having a more realistic expectation)

Also his kids do come over to visit us regularly and they will always be welcome in my house too, it's not like he's looking into replacing them or anything..

I thought that was worth the mention.
