@anon165949- Sophie’s situation is very sad. I agree with “gardenturtle” to an extent. However, from you are saying, Sophie is experiencing physical abuse and that constitutes police involvement. The school needs to know that you are pursuing the matter and, if it were me, I would demand some type of consequence to the individual or individuals that are abusing her.
Bullying in schools must be stopped. Your child should not be physically abused while she is at school. There was a case in Minnesota where a teenage boy was being beat up every day at school. The physical and emotional damage was severe and the family sued the school system. I would suggest letting the school board know that it will no longer be tolerated and you are prepared to take legal action.
