How they work
Child-Parent Psychotherapy
Core mechanism: Within the safety of the therapeutic relationship, the therapist helps the parent recognize how their own history (ghosts) distorts perception of the child, while strengthening protective relational patterns (angels) — healing happens in the dyad
Ontology: Young children's trauma symptoms are inseparable from the caregiving relationship — the dyad, not the individual child, is the unit of treatment; parental ghosts perpetuate intergenerational transmission
Play Therapy
Core mechanism: Play as the child's natural language enables expression, mastery, and processing of experiences that words cannot reach
Ontology: Children's distress is expressed through play, not verbal insight; play is the developmental medium for processing

What each assumes — and misses
Child-Parent Psychotherapy
Philosophical roots: Bowlby (attachment as survival system); Fraiberg (ghosts in the nursery — the founding metaphor); Winnicott (good-enough mothering, holding environment); object relations; Stern (intersubjective world of the infant)
Blind spots: Requires engaged caregiver — inaccessible when caregiver is perpetrator and unavailable; 50-session protocol is resource-intensive; limited to ages 0-5
Therapeutic voice: When he clings to you like that, what does it remind you of from your own childhood?
Play Therapy
Philosophical roots: Piaget (play as cognitive development); Vygotsky (play as zone of proximal development); Winnicott (transitional space, playing); Axline (child-centered approach via Rogers); Klein (play as child's free association)
Blind spots: Evidence base is modest; age-limited; transition to verbal therapy can be poorly managed
Therapeutic voice: [Following the child's lead in play] The bear is going somewhere safe? Tell me about that safe place.
Choosing between them
Child-Parent Psychotherapy (Attachment) and Play Therapy (Humanistic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
