Common behavioral problems in infants and children.

Primary care physicians can serve as important sources of behavioral information to patients of infants, toddlers, school-aged children, and adolescents. Behavior results from a blend of biologic qualities, such as gender and temperament, and social experiences, such as attachment and family experiences. Common problems include disorders of sleep, crying, feeding and diet, discipline and sexuality, aggression and biting, toilet training, and school avoidance. Family physicians should be aware of the management of behavioral problems and provide anticipatory or responsive guidance or reference information.
