Lashing out at peers

by worried
(UK)

My son is 7 years old and we have been looking for an explanation for his behaviour since he was a baby. Having had ASD ruled out we have recently been referred to an OT and are waiting for an appointment. Looking at the checklist he scores high in 8 of the areas particularly in Proprioceptive dysfunction, auditory dys, emotional dys, play dys and self regulation.

He is performing poorly at school despite being a bright child but more worryingly to us is his behaviour towards his peers as he frequently lashes out for no apparent reason, either in anger and frustration or just simply because they are there. The other day he banged together the heads of 2 of his classmates for no apparent reason, and was unable to explain his behaviour. His school are very supportive and understanding and needless to say we have tried punishments, incentives, talking through with him how other children feel etc. I havent seen much evidence of this sort of behaviour in other posts and wonder if anyone else has encountered this problem and can offer any advice.

HELP!
