This article explores solo motherhood by choice through a psychoanalytic lens, situating it within contemporary cultural change and assisted reproduction. Drawing on Mary Morgan's “creative couple”, Shelley Nathans' reworking of oedipal theory, and Lingiardi and Carone's “oedipal complexity”, it considers how difference and thirdness are sustained without an external couple. Golombok's longitudinal research, showing children in solo-mother families fare as well as those in two-parent families, challenges deficit assumptions. A composite clinical vignette traces maternal longing, symbolic meaning, and donor conception, highlighting the clinician's task of working with loss, desire, and the child's subjectivity in diverse family configurations.
