My ds is "solidly built" (at the top end of the normal weight for his height/age) and has been subjected to persistent verbal abuse relating to being fat from a classmate for the past 2 years. We have spoken to the class teacher and Head on a number of occasions, but the abuse has continued. My ds is very bright, but is now saying that he doesn't want to go to school. I am desperate to ensure that his self-confidence doesn't take a hit before he starts at secondary school next year, and would be grateful for any suggestions of how I should approach this issue.
