Sleep in the family.

Family systems are dynamic, with reciprocal interactions among family members. When children have sleep problems, they often awaken a parent, affecting parent sleep and subsequent parent daytime functioning. Child sleep patterns can also be disrupted by parent cognitions related to the child's sleep, as well as when parents are experiencing external stressors (eg, work or marital problems). This article focuses on sleep in a family context, reviewing the relationship between sleep among children and their parents from infancy to adolescence. Sleep in the family when a child has a chronic illness or development disorder is also reviewed.
