I think that I have a lot of feelings about
is that a lot of romance isekai are actually primarily about the power fantasy of being able to be a child again and have supportive family members who care about you and like
that's the whole thing, and maybe you're also a wizard or whatever but that's secondary
sometimes you are a wizard whose vast powers let you be a cool mom
i like those, too
it's true, being able to be good at taking care of people is also a big feelings power fantasy for me
what you don't see a lot of are stories where both the parent and the child have been reincarnated/isekai'd/time-looped/etc. Definitely room for some fun genre-bending stories there. I think The Villainess Flips the Script might be one?
"I’d Rather Have a Cat than a Harem! Reincarnated into the World of an Otome Game as a Cat-loving Villainess" does this whole family isekai
and its REAL good for it. KINDA SPOILERS BELOW
They even reincarnate at different times, the main characters mum and dad reincarnate as kids first and live whole lives together first. Then her older brother gets born, so her whole family know and are just waiting for her to remember her past life too - its real neat and implemented in an interesting way. I recommended the audiobooks if you like listening to fluff light novels like i do
