I'm in the process of having ds (8) refered for possible dyspraxia, so I guess i am looking out for unusual signs.
Today ds went to park and a friend of his grandad was there with his little boy. They ended up playing football together, and I noticed that ds was almost constantly making a two tone repeating hum. Loudly enough to hear easily a distance away where I was watching. He does this a lot when playing, not proper tunes but repeating noises. but I was suprised to hear him doing it outside, and with people he doesn't know around.
Does this strike you as unusual?
