Even very young children may show behavioural problems & especially those that are known as ?regulation disorders=, i.e. crying, sleeping and feeding disorders. Parents and caregivers are often pushed to their limits, endangering the relationship with the child during this vulnerable phase of development. This can result in long-term negative developmental courses, so that early treatment of behavioural problems in infancy and early childhood has a high preventive value. This book presents the most common psychological disorders in early childhood. In addition to the typical symptoms, the conditions that give rise to these and specific therapeutic approaches are also discussed.
