One of my students goes limp (on the floor or in a chair, will not move), crawls, sits under tables, or walks on knees or crawls when upset about something. We always have a talk about what is making them upset but it takes so long for them to tell me that sometimes, I can't get to them right away.

Other students see this behavior and the attention they gets from it, not from me, but from other students or teachers and now they have started copying these behaviors. The student does this mainly after lunch during specials. I have done if/then charts and reward charts. We have talked about more effective ways to get what they want and how to tell me that something is wrong. Nothing seems to work and stick. Help!
