Our youngest daughter had night terrors beginning just before she turned 2 and lasted until she was 6. Screaming is just one of the things common to night terrors. Children who suffer from night terrors will often appear awake, but will not respond to you when you speak to them. Sometimes they look around in panic at something unseen to you. Some children will try to get out of bed. There is nothing you can really do for a child suffering a night terror. For our daughter, she would have her episodes in the middle of the night. Blood curdling screams followed by loud crying would jolt us all from a sound sleep. After many episodes of trying to talk to her and calm her, we eventually learned to go to her bed, sit beside her, hold her if she would let us, speak calmly and quietly to her, telling her it was OK, mom and dad were there now. It would take between 5-30 minutes until she calmed enough for us to help her lay back down. Then we'd stay with her, rub her hair and her back until her breathing returned to normal. As she got older and more verbal, we'd ask her about her "bad dream", but she never remembered being up in the night. She also had nightmares which were considerably different. With nightmares she would wake with the same blood curdling scream, but when we went to her, she would grab us, cry in a different way, talk about her fears, and be able to remember the next morning that she had a bad dream. She is the youngest of our 4 kids and was born when her siblings were 18, 15, and 12 (long story - conceived unexpectedly when I had been taking birth control pills for 11 years!). None of our older kids had night terrors and the instances of nightmares were infrequent for them. We spoke several times with her doctor, especially at times when the night terror episodes seemed to increase. Apparently most kids outgrow them by about age 6 and our daughter did. Whether is was what was need to make them stop or she just naturally stopped, when we moved her to another bedroom she never had another night terror again. She is 10 now and is prone to nightmares, still, but generally foregoes the screaming and just shows up in our room and comes into our bed.
