My child has autism and is nonverbal. We have been dealing with inconsolable crying throughout the day and night with no desirable cause. We have been to doctors, specialists, ABA, and everywhere we can think if for help. The main issue we are facing is her waking up crying and staying up for about 4 hours every night. We are lost and it has been going on for months. The one thing we have noticed is that when she gets tired she starts crying. She always wakes up crying. She is 4 years old. Anybody else go through anything like this?
