Professor Karl Brisch, psychiatrist, psychotherapist, and researcher of attachment theory, first demonstrated in practice how John Bowlby's theory can be applied in counseling and psychotherapy. He called this approach binding psychotherapy – a method that can be both a standalone and an additional tool in the work of specialists. Professor Brisch dedicated a series of books titled “Counseling and Therapy Based on Attachment Theory” to the possibilities of binding psychotherapy in working with all age groups – from infant issues to adult complications. The third book in the series – “Preschool Age” – is dedicated to the development of attachment in children aged three to six years. The problems described in this volume include separation anxiety, aggression, jealousy among children in the family, adaptation to kindergarten, eating behavior disorders and sleep issues, etc. Many examples illustrate how various symptoms in children, often first manifesting in preschool age, relate to their life history and early childhood attachment experiences with their parents, and how timely help based on attachment theory can change the situation for both children and parents. This book is intended for everyone who works with preschool children and their parents: pediatricians, general practitioners, child and adolescent psychiatrists, adult psychiatrists and psychotherapists, nurses and caregivers, psychologists, social workers, educators, defectologists, specialists in therapeutic physical education, kindergarten teachers, as well as the parents themselves.
