Lulumama-My son is in year 2 and has a dx of selective mutism and a phonological disorder.
We were fortunate enough to be given a statement last year od 20 hours 1:1 help which has now been put in place.
My sons statement was applied for by the school as they did not have the extra resources to help my DS.
With lots of supporting reports from myself,ed psych,SALT,childrens services,doctor and a mental health worker.
At the meeting myself and DH were amazed at the number of people present,the head,his class teacher ,SENCO,2 people from childrens services,SALT.
But must say they were all vital in getting DS his statement .
It can be over whealming and as Peachy said intimidating but if you get them on side and put your points across and make sure you are heard they are invaluable.
It took awhile for me to get through to the school and some professionals that my son really needed the support and to make them understand DS's condition.
Just keep at it and don't feel intimidated.
I use to write everything down,discussions,dates,times,phone calls and have all information at hand with you at any meetings you attend.
Can be daunting and still is as we still have numerous meetings to attend but as time goes by you will feel more condifent in dealing with the meetings.
Good luck,let us know how you get on.
