If so, what are they in behavior therapy for and what do they do? My 2 year old bangs her head on the wall when she doesn't get her way. She will bang it so hard that it will knock pictures off of the wall. We've tried telling her no, we've tried ignoring her, nothing works. I spoke to her doctor about it yesterday and she said that she wants to put her in behavioral therapy. So I'm wondering what do they do?
