The investigators will provide parents access the Cancer Care Companion through Epic MyChart. If a participant has not enrolled in MyChart, the investigator will provide instructional materials and assist with registration. Parents will use the Cancer Care Companion for 3 months during which they will complete tasks including educational modules, check-in surveys, and patient stories. Participants may opt-out of receiving the patient stories. During the 3-month intervention, participants will receive 13 educational tasks, 7 check-in surveys, and 5 patient stories (if requested). The Day 1 educational task will include an overview of the program and further instructions. After enrollment, participants will retain access to Cancer Care Companion for at least 3 months, during which they can revisit the content.
