I have a strange problem - my son's autistic and nonverbal. Recently he's been ripping his socks everyday. He keeps pulling at them until them get a a ladder and then he rips them apart. They are the right size and I try to put them on him myself. But he doesn't let me. Also I can't let him go without socks as it's so cold. Can anyone help me? Please tell me what I should do? Thanks a lot.
