This book is the result of efforts by an expert study group, set up by the Association for Child Psychology and Psychiatry, to examine the relationships between infant crying, sleeping, and feeding problems, and to shed light on the developmental and regulatory mechanisms involved. It brings together research from a variety of professional disciplines. Following an introduction, the three sections examine crying, feeding, and sleeping, respectively. The chapters are: (1) "Infant Crying: Normal Development and Persistent Crying" (Ian St. James-Roberts); (2) "Explanations of Persistent Infant Crying" (Ian St. James-Roberts); (3) "The Treatment of Problem Crying Behaviour" (Dieter Wolke); (4) "The Infant's Regulation of Nutritional Intake" (R.F. Drewett); (5) "Mothers' Ideas about Feeding in Early Infancy" (Peter Wright); (6) "Feeding Problems and Their Treatment" (Gillian Harris); (7) "The Physiology of Sleep in Infants and Young Children" (Zenobia Zaiwalla and Alan Stein); (8) "The Development of Sleeping Difficulties" (David Messer and Martin Richards); (9) "Sleep Disturbance in Children and its Relationship to Non-sleep Behaviour Problems" (Jim Stevenson); (10) "The Treatment of Sleeping Difficulties" (David Messer); and (11) "An Overview of Infant Crying, Feeding and Sleeping Problems" (David Messer and others). The book includes an index. (AS)
