V.S.
I wouldn't simply assume the girls and the moms are mean. I find it hard to believe all these people, including the teacher, are simply ganging up on your daughter. To what end? If she was struggling in school - either socially or academically, it is quite likely she is acting out in very undesirable ways and these people all have valid, if hard to hear, points. You don't say what it was your teacher took issue with - was she talking about your child's behavior? Her academic performance? If she was struggling academically, it may have led to her misbehaving in class and not trying. A lot of times, situations with this begin with an undiagnosed learning disability. I would start by talking it over with your pediatrician and seeking counseling of some sort. But don't simply assume all these people are ganging up on her. They're seeing something you can't or don't want to.
