My son is autistic, ADHD, and Tourettes

Hi,

 my son is highly repetitive. He has recently been diagnosed with Tourette’s. I’m use to what he does. I need help to what I can do when he does them on how I can redirect and what I can get him to do something else. He is obsessed with washing machines and he shakes EVERYTHING. He helps me with laundry. I got him a little washing machine but in ABA he shakes everything and wherever we go he finds things to shake. It seems this is a soothing to him when he does it. He does ABA but he won’t stop and it is really interrupting the other children and therapists there. HELP! What things can help him? Thanks
