Have you read "I became the Despised Granddaughter of the Powerful Martial Arts Family" iirc, it shows more of like martial arts and ability, it could be up your alley.
Or you go find on a masterlist on this platform

There is some that could be your thing and there is a part two too
Or go to Reddit to find some
-[REC] Looking for Childcare OI (from POV of child) electric boogaloo- and -Baby/Child MC Reccs :)-
Those are some of the reddit posts, there are some good recs on those posts.
Hi everyone!! I'm looking for a classic ヾ(❀╹◡╹)ノ~childcare recommendation where the MC is adopted or is born into the family or anything like that please but I'm specifically looking for ones where our MC is interested in swordsmanship or something along the lines of fighting and not using "divine power or only spiritual powers" It's fine if the MC likes both though!
This is my second time posting so if you replied to the first, thank you very much!! (●'◡'●)ノ
Thank you everyone for any recommendations you may give!!!!! <333ヾ(☆▽☆)
