HI prudencepinkleg-My son is 6 and has selective mutism and speech problems.
He also displays some sensory issues.
We are currently going through the statementing process and hope to get him some 1 on 1 help.
He is in year 2 at the moment.
I had real problems getting him to school last term and the outbursts you describe we were getting at home but not at school.
He is an anxious little boy and hates loud noises and crowds.
He has settled into year 2 a lot better and I am going into school twice a wek for sliding in sessions to help his confidence.
As for your DS I think the school were put of order excluding him and am pleased they need see to be getting advice on how to deal with this and understand it.
Was your DS talking in reception?
I've found from my Ds that he needs someone he can trust in school and feels comfortable with and not to be made to feel under pressure.
Getting into a routine and explaining any major changes also eases my sons anxietys.
It is difficult dealing with people in a school who have no idea of your sons problems and a paediatrician or an ed psych will be of great help in getting them to give your son the right support he deserves.
Excluding him and delaying the issue is'nt helpful,they need to deal with it.
It would have been a big thing for your son as with my son with his selective muteness to start a new school with new teachers and new children.
With my ds ,he does'nt talk at school but tends to have moments of extreme frustration and shouting when he gets home.
It must be so difficult and the anxiety builds through the day and the only way he knows how to realise it is in this way.
Maybe your son is anxious in school and concerned about talking so lets out his frustration in other ways?
