Play, so suited to holding multiplicity, was given a full range of articulation in this engaging paper, “Mummy at the Door,” from the literal physical dimension, such as the materials used, masking tape, rope and string, to the symbolic level, elucidating the metaphors expressed through their use. Simultaneously, play served as the frame, moving from working with each individual member of the family to registering the implicit relational dynamics among family members. Play defined the fluid, nonlinear systemic process that met the needs of a young boy’s therapeutic journey through developmental and real life challenges. As a result, we are treated to a moving portrait of a therapeutic process, without which it is hard to imagine this young boy growing up.
