My life with an autistic child

Some nights he just won’t sleep. Those nights are especially hard because I am tired and I want to sleep but I can’t because he is awake and can’t be left awake alone. I try to keep a level temper because I know that the sleepier I get the grumpier I am. On these night I never know exactly what to do to get him to sleep. We pretty much have to wait it out. Some nights he doesn’t pass out until 3am.
