His dr mainly talks to him and works with him on things like appropriate hand motions and body language. I am still foggy as to how she getts through to him so well, but, his grandparents have started noticing a difference w/him already too. My parents noticed that at the beginning of there visit how he was (he went 3 wks between appts this time) and how he was after his appt. He calms down much more. She just mainly talks to him right now, but the changes are awesome. Even meltdowns are much more calmer.
Wish I could tell you more, but, I haven't quite figured it out it myself.
