The burgeoning research in attachment theory, affective neuroscience, polyvagal theory, epigenetics, and trauma treatment has given new directions for the practice of prenatal and perinatal psychology. The authors offer essential fundamentals for the integration of these new principles into clinical practice with individuals and families from pre-conception through adulthood. Within attachment theory, affective neuroscience, and the clinician as key instrument in the healing process, the authors delineate six phases of pre- and perinatal therapy, including specific principles and practices for each phase.
