Posting on behalf of a friend here. Her ds - let's call him A - age 7 is being bulled - or at least targeted - at school by one boy, B. The other boy has SN (we think; nightmare in class, constantly in trouble, very tricky at social clubs and parties, needs one to one supervision).
A has been strangled, been knocked down, been bitten on the bum, been headbutted, been punched, been knocked down and then B sat on his head (the most recent). My friend has been in to see teacher and HT several times but no joy. They say they're aware of B's problems and will keep an eye on it, but don't have the money for a one to one TA for him to supervise him (!!). Last year, they kept B in at playtimes, but not this year.
Friend's DS A has been having nightmares and migraines for past 9 months - brought on by stress, she thinks. Doesn't want to go to school.
What else can she do if the school won't take her seriously? School is also not communicating with B's parents what is happening as B's mum asked A for playdate last week and was horrified when A didn't want to go 
Help, please! A's mum is at the end of her tether. (School is in Scotland so no board of governors to approach, just HT then local authority.)
