Currently, there are two types of pediatric disorder books available: high level technical books geared toward pediatric specialists, and self-help books for parents. The technical books cover diagnosis and treatment, while the self-help books cover general problems, are single authored, and speak little to the research of any given disorder. This volume consists of focused articles from the authoritative Encyclopedia of Infant and Early Childhood Development that cover the research information on common disorders in age 0-3. Topics include those most typically occurring, making them of great interest to both specialists and nonspecialists. Disorders and dysfunction of a variety of types are discussed, whether cognitive, social, emotional, or physiological. Coverage includes asthma, allergies, colic, bedwetting, diarrhea, genetic disorders, SIDS and learning disabilities, and provides an essential, affordable reference for researchers in developmental psychology, as well as allied health fields.
