Sounds just like me when I was a kid. My mom did cool looking braids as a kid, so I suggest you braid her hair. But what you should do first before braiding her hair is use some kind of a oil or moisturizer. My mom always used coconut oil, but its best to use curl ehancing smoothie or any moisturizer and this gives a good slip to detangle her hair and then seal it with coconut oil. After sealing it with coconut oil, I think its best to do singles. Dont make them to big or too small, and its best to leave them in for at least a week, if you want to take them out so her hair can be naturally curly. Let me know if you want me to clarify more.
