High pitch screeching

Hi all I'm very knew too all this, my son is 7 and is currently going through an autism diagnosis.....which is taking absolutely ages. I've been trying too look up as much as I possibly can. But he does a  high pitch screech when hes over stimulated..could be while watching the telly on his ipad xbox playing a game certain words....any one have any ideas as to what and how too deal with this its soo high pitch.....thanks Blush 

  • Yes this is what we've been doing.  thing. Its very tricky as we have 2 other children. We have reduced ipad time as he tends to hit the ipad. I just wonder if some fidget toys would help?!

  • Sounds like vocal stimming perhaps? Anyway, distraction might help, or perhaps reduce the time spent on the triggers.
