I have a very sweet, very kind, very smart student who chews on his hands all day long. He also spits on his hands and licks it off. He has Autism. When you tell him to stop, he will for a split second. This is his first year with me. The smell is nauseating. I have a very high tolerance for smells. But this is BAD! Things they have tried in the past: -Giving him other things to chew on. -Giving him gum. -Making him wear gloves. (He takes them off) Things I have tried: -Social Stories (he can read them independently) According to the parents, he has done this his whole life. Our OT doesn't have any suggestions. She has worked with him a long time and has tried the above things already. PLEASE HELP if you have any recommendations. I have my wonderful students for 4 years, and I don't know if I can put up with this smell for that long.
