For the vast majority of children acquiring speech and language skills is an effortless process. However there is a sizeable proportion of children for whom this is not true. Difficulties they experience may be associated with other conditions such as cleft palate or hearing loss or they may have no obvious cause. This book provides a comprehensive picture of the difficulties that occur when speech and language does not develop in the young child. Divided into two sections the first focuses on how such children should be identified and assessed. The second section provides specific insights into communication difficulties in different conditions. Each is written by an expert practitioner and is illustrated with specific examples. Based on best clinical practice and research-based evidence it is a practical guide fully referenced for those who wish to develop knowledge further. It is essential reading for all professionals who work with children particularly those who work in community settings.
