This humane and sensitive book gives practical advice and support to parents of chronically ill children and to those involved with their care.  Audrey McCollum deals sensitively with both the physical and emotional difficulties these children face at each stage of their development as well as the unique pressures encountered by their families.  She focuses on ways to meet these challenges and to make the ill child's quality of life as meaningful as possible.    First published in 1975 as Coping with Prolonged Health Impairment in Your Child, this revised enlarged edition contains a new chapter dealing with the problems of these children as they grow into adulthood.    Reviews of the first edition:   "For the parent of the seriously or fatally ill child... I know of no better source of help than Audrey T. McCollum's sensitive and highly professional book." -Louise Bates Ames, Co-Director, Gesell Institute   "A thoughtful, practical guide for parents.... The book reflects a seasoned and extensive clinical experience in helping parents achieve the self-reliance, openness and ability to use the help of others that comes with knowledge of their child's specific disorder and developmental needs." -Morris Green, M.D., Children Today
