Hi, Your granddaughter is
Hi, Your granddaughter sounds as though she is starting what some would consider normal "teen" behavior. However, taking things away is counter productive. Grounding doesn't work. It will become a battle of the wills. There is a book that I use in my practice in fact I always have several copies on hand for parents of teens. It's called "Surviving your adolescents" by Thomas Phelan. It is a great book that gives your concrete ways to get through these rough years. It's available at any bookstore or online.
