This book presents an interdisciplinary discussion between researchers and clinicians about trauma in the relationship between infants and their parents. It makes an innovative contribution to the field of infant mental health in bringing together previously separated paradigms of relational trauma from psychoanalysis, attachment and the neurosciences. With contributions from a range of experts, areas of discussion include: intergenerational transmission of relational trauma and earliest intervention the nature of the traumatising encounter between parent and infant the therapeutic possibilities of parent-infant psychotherapy in changing the trajectory of transmitted trauma training and supporting professionals working with traumatised parents and infants. Relational Trauma in Infancy will be of particular interest to trainee and qualified child and adult psychotherapists, clinical psychologists, child and adult psychiatrists, psychoanalysts, health care professionals and social workers.
