I am a lefty and I remember all to well the times a crayon or pencil was grabbed from my left hand and corrected. It has never stopped me from doing anything I wanted to do. I don't see a problem. How you get things done doesn't nearly matter as much as just doing it. I taught myself to quilt, use power tools, ride a bike and even eat with proper utensils, all while being left handed. Please don't treat it as if it were a disease. She will figure out her way as we all do, lefties and righties alike.
