Dan and Kim published the ‘Healing Relational Trauma Workbook’ in 2024. This provides DDP therapists and practitioners with a comprehensive understanding of Dyadic Developmental Psychotherapy, Parenting, and Practice (DDP). Within the Workbook, there is an important emphasis on reflection and self-understanding by the therapist. In this presentation we will explore how individual differences, often influenced by past relational and attachment experience, can impact on the therapist’s practice of DDP. Self-understanding can help the therapist to develop their practice, understanding their own unique strengths and challenges, so that they can ‘sit with the uncomfortable’ able to offer co-regulation and co-creation of affective-reflective narratives with the children and families they are working with.
