We would recommend for her daughter to drink the Female Health Tea, a cup a day. Nature is taking its course and all you can do now is to get in tune with it. Poor diet may be the reason why she is going through puberty at such a young age. It's probably too late to try and stop her period but it is never too late to start eating healthy. She needs to stay away from animal products and processed foods. Her diet should consist of mostly fruits and veggatables.
