I think, 'MY DAUGHTER IS THE FINAL BOSS', might fall under what you're looking for. The dad reincarnated back in time and is trying to do a better job of being a father and protecting his daughter while she's still a child. It's like the dungeons and Hunters in the modern era type. I only read a few of the beginning chapters long ago. So I don't remember a whole lot. Thankfully the name is easy to remember or I would have lost that one along with all the others from my lists.(⌒▽⌒)

Please give me some cute kids (where it’s an actual kid and not an adult in a kids body) childcare/found family manhwas/mangas. I loved “on my way to meet mom”, and I love reading “secretly capable child seeking of her dad” and “sister-in-law of the tragic reverse harem male leads” for manhwa and spy family and gakuen babysitters for manga
