My just turned 9yo son did NaNoWriMo, and he vastly improved his touch typing to the point of not being frustrated in one month. After the new year, we are going to try and work through and editing process for grammar/spelling at least.

Anyway, if you can get her to do the typing for at least a little bit every day, she will improve and hopefully get tired of "waiting" for you to be able to do the typing for her.

Good luck!
