well there is a lot where they are transmigrated or reincarnated, and start as kids... like lady baby, and the youngest princess. Not too many are the mc being real kids. I thnk “The monster duchess and the contract princess” i also recommend “ The Tyrant’s Guardian is an Evil Witch” the mc is the witch, but the ml started off as a real child, and its really cute~
Daughter of the emperor Suddenly became a princess one day Am I the daughter The Twin Sibling's new life The archmage's daughter Choose your real daddy tyrant I became the hero's mom I am a child of this house, I was born as the Demon Lord's daughter, the precious sister of the villainous grand duke
can someone recommend something that the mc/ml is kid or a manga that having a kid, dang, i've been dying to see cute kids!!
