My niece (nearly 9) is being bullied by 3 girls - formerly her best friends. Sister reported it to head of year, niece has moved class this week, but the girls are persisting in harassing her at play time. To deal with this, the head of year now says my niece should stay in at play time. Head of year will not involve the parents - one of whom is a teacher at the school. How can I help my poor niece and sister? Desperately worried and sad for them both. (I have re-posted this from another topic area)
