Hi, ds(5) with ASD, hearing loss, s&l delay - everything else relatively ok, we kind of get by... sleep hasn't been a problem for ages, but suddenly about 3 weeks ago, he's not settling - staying up til 10,11, 11.30 and causing havoc generally in the process. Tonight, he got paint and covered his window and his brothers window and chair legs and his own legs... mare. Is it the weather? What else could it be? And HELP!!!
