My 7y DD has had a tough time since sept. a girl in her class dominated her in past 18 mths. Didnt like her playing with anyone else but v quiet and sneaky. Had my suspicions all no good but she is a quiet girl and hides her manipulation well. In sept she dropped my dd like a stone and then began excluding her from games in break time taking the other 4 girls with her. My dd then left on her own with no one to play with. She has fallen behind massively from top of class to barely doing anything and sitting near support group. Went to see head who said other girls don't like my DD. says it will be very tricky and take long time to fix. my dd is v unhappy, not sleeping well, compulsive hand washing etc. She has friends outside of school , no problems, lots of play dates etc. she is very pretty and well liked outside of school. Now i discover that the mean girls dad is calling my dd names 'whingeing gingerhead and redhead monster child" and this is what other girls in class now calling her. should I move her? There is a place in village school with girls she knows and gets on with. A small established group so worried it may happen again. Don't know what to do......
