Caring for medically complex children (MCC) involves physical, financial, and emotional challenges for parents, who are often grieving the loss of their expectations or vision for a healthy child. We applied Miles' parental grief model to explore the experiences of 25 parent-caregivers who were interviewed for The Rare Life, a podcast in which a mother of a MCC interviews parents about their experiences caring for their MCC. We characterize parent-caregivers' experiences of shock; their intense grief, including yearning, helplessness, physical symptoms, behavioral changes, and a search for meaning; and the reorganization that helped them accept their parenting reality. In addition, we identified communicative barriers and facilitators that hindered and supported parent-caregivers' movement through the phases of grief.
