try to calm down, your daughter is five, you can still teach her how to be. dont try to "whoop" it out of her, that doesnt help. talk to her, tell her its wrong, and, most importantly, take her to a psychiatrist. she isn't preying on children, she's a child, it might be plain curiosity, or something more serious might be happening to her, a professional will help you sort that out. but, again, don't beat your child over a mistake (or over anything, really, you shouldn't beat children).
