I'm a Child and Youth Worker (counselor for children and youth with emotional, behavioral and mental issues). SOMETHING is going on with her. Different children act in different ways when something is wrong so you won't be able to pin point it but she does need to be seen. If this behavior is still escalating with consistency in consequencing the underlying problem must be dealt with before and behavioral issues can improve. Is she the same at school as well?

I know how difficult it is to tell parents that there is something wrong. You need to try again, and again, and again. If things don't change you need to terminate them as the other children will be GREATLY affected by her behavior.
