Infant observation and its applications still constitutes the bedrock for understanding the origin of the human mind, and the training of all the authors is rooted in this method of observation as well as in the work of later object relations clinicians and theoricians (Klein, Bion, Winnicott, Meltzer etc). The authors from the São Paulo Mother-Baby Relationship Study Centre, working in the fields of infant, child and family psychology, cover a variety of interesting settings, such as: the seminar room where Esther Bick herself led a discussion group; the homes of observed babies; the consulting room with parents and children in therapy; a nursery; a child psychiatric hospital department; and a neonatal intensive care unit. The book ends with an innovative and timely chapter on research on the link between maternal reverie and the development of symbolic play in babies.
