Theraplay is an evidence-based dyadic child and family therapy that has been recognized by the Association of Play Therapy as one of the seminal and historically significant play therapy approaches for children. Developed over 50 years ago, and practiced around the world, Theraplay was developed for any professional working to support healthy child/caregiver attachment. Strong attachment between the child and the important adults in their life has long been believed to be the basis of lifelong good mental health as well as the mainstay of resilience in the face of adversity. Modern brain research and the field of neuroscience have shown that attachment is the way in which children come to understand, trust and thrive in their world.
