Good idea about 810/ss+ Disney, thats what I did last time, and it worked, but for somw reason I just cave in when I get home. I'm also really tired these days its been hetic at school lots of TA's off sick, and we have to cover their pupils as well as act as scribes for pupils sitting GCSE's we just don't seem to have a minute.
As for your son, it is hard, and if the pupil doing the bullying has a statement or is "looked after" or has lots of agencies involved, it makes it harder for the school to do anything, because of the "child's rights" working in a school I see situations like this all the time and we (TA's) often say what about the rest of the class and thier rights , but schools hands are often tied, they do get suspended etc, but seem to "get away" with a lot more than other pupils, but the school will be doing their best , I'm sure, but just make sure you keep a log of any incidents that affect your son.
