I have a 13yo boy who is autistic and has ADHD. No matter how many times I explain the steps, his hygiene is lacking. I'm talking bathing, hair care, nail care, everything!! I'm desperate here. I've been looking for videos to see if they'll hold his attention and explain things better, but everything I find sounds like they're talking to a 7yo. Also, there's a startling lack in consistency, and now I'm questioning my own practices! Any recommendations on videos or series for this? I'll take book recommendations, too!
