My 4yr ds hasnt gotten an official diagnosis yet, I am in the process of that. One of the hardest things for us is when he gets upset and shuts down. Yesterday when it came time to pick my dd up from school, he did not want to go. he was on the floor curled up in a ball screaming, I couldnt get thru to him. i finally got him to get his shoes and coat on and the entire way to the school he screamed, thru himself on the ground, etc. Its like when this happens he shuts down and does not even acknowledge me. Is there any way to get thru to him and calm him? I feel so bad :( I do not yell, i try my hardest to stay calm and talk softly to him in hopes that my calm tone will help him calm down, but it doesnt seem to work very well.
