Today he didn't want to go into school and ran out of the school gate, up the alleyway which comes out next to a main road. It's almost a third of a mile, maybe more away from the school. He just ran and ran hell for leather with the teacher pegging it after him. He stopped at the main road though and just waited there for the teacher to catch up.
Eventually he came back to school, senco, teacher and dh (who went looking for him too) had a crisis meeting. Have agreed to have a teacher meet him to take him into school from tomorrow.
Nightmare, he is getting worse. I think a statement has got to be the way to go now. He has lots of extra help already and has to be taken out of class regularly throughout the school day due to his disruption and aggression. School are very good with him but I fear he will end up in a special school at this rate.
