Anyone out there have the above issue with there child. My 9 year old son has gone from fingernail and everything else chewing to now picking skin sores up both arms and legs. He doesn't do these activities at home but only in school. We are working on his 504 plans but just wondered if there were any others out there with this issue and any tips you can offer beyond fidgets, gum chewing, and meditation. He is also paranoid about bugs and now goes into a full fledged freak out when seen. We do meditation but that doesn't seem to be cutting it.
