So, what I'm looking for are novels about rebirth. BUT the novels must be about the MC transmigrating/experiencing rebirth/time-travelling into the body of a child or a baby. The time period can be in the past, present, or future. One example is the novel called "My Daughter was my Sworn Enemy in my Past life." Thank you!! Child: 3 to 8 years old
Don't think I have anything for you but you should probably not put this thread under "resolved", got me confused there. Also you should probably put an age limit to the word "child"

If you search with reincarnation tag, you will realize about one-third of them suit your criteria. PS: btw, I meant JP novel with reincarnation tag
