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
Theraplay
Core mechanism: Recreating early attachment experiences through structured, playful, nurturing interactions between caregiver and child to build secure connection
Ontology: Insecure attachment results from missed or disrupted early interactions; these can be repaired through direct, embodied, playful relational experiences

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?
Theraplay
Philosophical roots: Bowlby (attachment); Winnicott (play and transitional space); Stern (attunement); right-brain developmental neuroscience
Blind spots: Directive approach may not suit all families; limited evidence for older children/adolescents; requires caregiver participation
Therapeutic voice: Mom, I want you to put lotion on Jayden's hands — really slowly, one finger at a time. Jayden, your job is just to receive.
Choosing between them
Child-Parent Psychotherapy and Theraplay both sit within the Attachment tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
