Using a novel computer decision support system in several primary care clinics, caregivers accompanying their child to a health visit will be randomly assigned to receive two of five items assessing night wakings and/or sleep problems, followed by a validated questionnaire for infant night wakings. If caregiver responses to the items suggest a possible sleep problem, pediatricians will receive a prompt in the electronic health record identifying a possible infant sleep problem. A sub-sample of caregivers will then be interviewed regarding the content of the visit that day.
