Very few of the reasons that an autistic child is “acting up” are because of purposeful defiance or disobedience. Punishment is both inappropriate and cruel, and seclusion, while frequently advertised by its proponents as a way to safely calm down, is in actuality one of the harshest of punishments. A terrified autistic child melts down, confused and overwhelmed, and they are put in a small, confined space to work it out on their own. This isn’t modeling what we want them to do differently next time. This isn’t helping them, soothing them, or looking for a source of their distress.
