My Smart Head Banger

This chick is too smart. Her favorite stims have to do with her head, mostly hitting the side of her forehead. Sometimes very hard, mostly when she is tired or something is wrong. Her new stim. (overall her stimming has lessened) is bouncing her head off the couch. She sits with her back to the couch and bangs/bounces the back of her body off the couch cushions. If she is in front of the arm of the couch it is hard and she cries, then scoots over to where the cushions are, LOL. She tests banging her head on other surfaces, like walls, tables, floor, but she does it very slowwly and only once then she decides, nope that will hurt. Thank God!! I let her bounce her head off the couch because it's much better than any other surface!!
