Not sure if this is what you mean but this belongs to the "reincarnation/suddenly part of another world" type of story. And although it doesn't rly have to do with raising children and stuff, she kinda does change the plot. But this story is so different from the others that ive read of this kind, that I have reread it for five time in the last two months and written a whole essay about why its so unique. I recomment 100%

looking for reincarnation webtoons/manga/Manhwa like "I raised cinderella preciously" and "I became the villains mother" or "I'm only a stepmother but, my daughter is just so cute" basically just female or male character is reincarnated and they raise children and try to fix the future! it's just cute!!!
