My dc is 5 years old and is autistic. He sweats often in the night and often wakes up distressed and agitated in his sleep repeating the same phrase over and over ( like oh my goodness or I have a cough when he is ill). It is alot more frequent and worse when he is ill and happens many times throughout the night. He also will not sleep on his own and gets very upset if he wakes up and is alone in bed. Is this called night terrors? Anyone have experience of this or advice? Thanks
