love shuttle

There's always the classic 'Who made me princess' XD

But do you mean transmigrating into a child? Or do you mean a reincarnated child? Please clarify ヾ(❀╹◡╹)ﾉ~

My bad, I mean transmigrating in a child

There's this:

https://www.mangago.zone/read-manga/i_became_the_wife_of_the_monstrous_crown_prince/ - but I'm not sure it completely fits what you're looking for.

Then there's:

1- Lady Baby - which fits what you're looking for except rather than transmigration, it's a sort of reincarnation/time travel mix but the premise is the same as most child transmigration mangas.

( https://www.mangago.zone/read-manga/lady_baby/)

2- Survive As A Hero's wife, alt name: The Villainess Wants A Divorce - A modern-day woman transmigrates in the novel she was reading and finds herself in the body of the villainess when she was a child.

( https://www.mangago.zone/read-manga/survive_as_the_hero_s_wife/)

3- Beware Of The Brothers - It's not transmigration but reincarnation/time travel, but it does include an adult in a child's body (which, AGAIN is what happens in kiddo transmigration mangas).

The FL lives a hard life with brothers who don't like her bc they feel she's trying to replace her actual sister, she dies and wakes up in her younger body.

4- The Youngest Princess - It's a unique take on the usual transmigrated as a child fics because instead of being transmigrated from the modern world, this person is an archmage who dies(?)(we're not entirely sure what happens to her) and is reincarnated into the body of the youngest princess of a powerful kingdom she recognizes (takes place in a fantasy universe), watch as she gets her father and both her brothers wrapped around her chubby lil' fingers.

5- Who Made Me A Princess? alt name: Suddenly Became A Princess One Day - AHH ONE OF THE BEST MANGAS I'VE READ, the art is GORGEOUS and for this one I can't actually summarize the plot without spoiling it for you so I'll just let you figure that part for yourself ;).

( https://www.mangago.zone/read-manga/suddenly_became_a_princess_one_day/)

BONUS MANGA!:

When the Evil Girl Loves - The art is just as beautiful as Who Made Me A Princess? if not even MORE GORGEOUS, I haven't actually caught up to the manga on this one yet but I do love it enough to send it here <3

ALSO THE AMOUNT OF MISUNDERSTANDINGS HERE IS HILARIOUS!

Summary:
I’ve transmigrated into the body of the terminally ill, villainous princess of a novel. It’s okay, though, I can cure this illness and live a life where I can do whatever I want! First, I want to meet all of my favorite characters from the novel in person! But, because I am a villainess, people around me tend to be wary… “You will die soon, and yet… how can you laugh like that?” Well, it’s ‘cus I’m super hot.

Also.. damn did I really spend an hour writing this? XD
WELL I HOPE YOU LIKE IT! ヾ(❀╹◡╹)ﾉ~

AHH JUST REALIZED IT'S 3AM AND I HAVE CLASS TOMORROW T^T RIP ME, HOPE THIS WAS HELPFUL!

*awkward silence* I- I just realized I'm probably bombarding your notifications.. ╥﹏╥

But I forgot to send the link for the bonus manga...
