AIBU to expect my primary age children to be able to go to school without being attacked by older/other children, see other children attacked now and then like it’s completely normal now? I have the impression that our school has just caved. It’s like they accept a certain level of violence is just inevitable.
Cut this as short as I can- first incident this year my son was attacked in year 6 by another year 6 in an unprovoked attack, it was nasty he was repeatedly kicked on the ground. Teachers had to be found. Second attack by the same pupil on my younger sons friend. Went pretty much the same way, except this time it’s a year 6 boy attacking a year 3 child. Again no teachers about they had to be found. Third incident- last week, my year 3 punched in the stomach by a year 6 boy after he refused to get off a bit of play equipment he was being told to get off of. No teacher. I feel awful as I had told him to stick up for himself as this child had been bothering him and his friends on and off for a while. Also- no phone call from the school, to tell me my child had been punched- I found out direct from him when he was sent home with a sore tummy.
I suppose what I’m asking is does anybody think this is reasonable? 
Is this now ok? Are other parents feeling as exasperated? And has anybody had any success in stopping this kind of thing happening at their school?
