This book illustrates why a holistic approach is important in Pediatric Palliative Care (PPC). Readers will learn this approach has a horizontal axis, featuring the patients mental and physical needs, as well as their environments. It has also a vertical axis : the evolutive changes of the patients throughout their development and their illness, their aspirations and fears. An evolutive (or dynamic) approach is mandatory. Each child/parent has a different experience of illness and a different path to recovery that is influenced by their age, gender, culture, but also by the state of their grief. To take care of them, we need to know the state of the subjects we are dealing with throughout their evolution in age (children) and in sorrow (both children and parents). Jung s and Piaget schemes will be of support. This book also helps caregivers to know what ethics is.
