Eligible families will be provided with website access instructions. Parents and children will be instructed to review the materials separately. The intervention will provide each person with individualized action items to be discussed as a family. It is anticipated that reviewing all of the psychoeducational materials will take the parent/child approximately one hour, resulting in a total intervention burden of two hours for the family. Participants will be encouraged to return to the website as often as needed to review content. For the purposes of this project, they will be instructed to review all intervention materials within one month of receiving the website access instructions.

The website will incorporate animations/illustrations to enhance comprehension, patient stories, and video-based expert explanations.

The materials will address the following content areas:

• Provide families with data demonstrating how prevalent social relationship struggles are for children with CDH.
• Describe specific social challenges that commonly affect children with CDH.
• Explain the impact that medications typically prescribed for CDH may have on social relationship health.
• Help families advocate for their child's social needs at school.
• Support children and their families in decision-making about appropriate disclosure with peers at school and in extracurricular settings.
• Offer strategies to support families in raising the issue of social relationship health with the child's sleep physician.
• Provide a list of programming which offers children both structured and unstructured opportunities for social engagement
