DS is almost 9 and has a diagnosis of ASD, Learning difficulties and ADHD.
Over the last few months he has been struggling to get his words out, and is saying yes mid sentence constantly. So he will say - Today at school yeah mum, yeah we were baking yeah yeah, and my friend yeah Toby was yeah helping yeah me. All with lots of pauses as he struggles to find his words. He doesnt seem to notice he is doing it, but its now at the point where he is constantly losing his train of thought, and forgetting what he wanted to say. 
School are going to do a SALT referral, but the wait i suspect, will be a long one. Im not sure if i should contact his pead for advise in the mean time.
Your thoughts please.
