Rory, I don't know the proper term but I've learned that kids with autism fixate on certain things. My daughter has put herself in charge of family dressing. If we don't change from pajamas quick enough, she will drag us to our bedrooms over and over until we change. This, I can live with. She also critiques how we are dressed by trying to remove any clothing she doesn't like. This is not acceptable. I just haven't figured out how to stop her from tearing at my cloths. Any ideas? BTW she is nonverbal.
