Our little boy, Daniel, is severely autistic and currently going through a particularly difficult spell.
He has taken to loooong spells of shouting "A" and "EH" at extreme volume over and over and over again, generally in the middle of the night. He takes absolutely no notice of any requests asking him to stop. If we do manage to settle him, within moments of leaving the room he's often out of bed starting up again.
This is a plea for our sanity - does anyone have any advice, perhaps having gone through any similar experience, and generally anything we can try to reduce this type of constant "verbal stimming" behaviour?
