My 9 yo (ASD ADHD & anxiety) has always been a great sleeper. Lately though, he has been waking and having a hard time going back to sleep. He is also scared easily so, if he has watched something he thinks is "scary," he will have trouble going to sleep. I know some kids try melatonin for sleep issues. Is this something to discuss with the pediatrician? Any one else dealing with sleep issues?
