Parental advice giving serves as an important form of informational support for parents of children living with complex chronic conditions (CCCs). These messages can provide backchannel insights into social challenges, best practices, and may offer different forms of experiential wisdom garnered from their own parental caregiving experiences. Contributing to the naturalistic, health-context investigations of advice messages, we interviewed 35 parents who discussed their experiences with parenting their medically complex child. Part of the broader interview protocol asked parents about advice they would offer to other parents like them. We conducted a thematic analysis of parents' responses to these questions to understand advice content, form of advice giving messages, challenges experienced by parents, and suggested best practices for managing a child's CCC. We present our findings and discuss implications on educating health care professionals about how to cultivate advice networks and the need for more parent peer mentoring programs.
