Parasomnias are disruptions in your child's sleep. Night terrors may seem like nightmares, but they are far more intense. During a night terror, you may not be able to comfort your child. Signs of a night terror are sitting up in bed, shouting or screaming. During sleep walking, your child may seem confused or partly awake. They may either stay in bed or walk around without seeming to be aware of their surroundings. The next morning, children often will not remember either night terrors or sleep walking. While scary for parents, night terrors usually do not harm children. In some cases, though, night terrors and sleep walking may be a sign of another sleep disorder that your child has.
