Take action, she may have it or a form of it too! It goes through genes very well. Give her attention for GOOD THINGS SHE DOES. Like cleaning up toys, drawing you pictures, dressing herself in a nice outfit, how pretty her hair looks or her eyes, how well she eats, how sweet she is, sharing, caring, kindness, sports, playing outside, learning, school, arts. There has to be something you will find and give her attention for that not for stealing and breaking toys saying bad words etc. Good luck!
