Within the depth-psychology corpus, ‘Child Psychology’ occupies a peculiar and contested position — neither a settled subspecialty nor a mere tributary of adult analysis, but a site where foundational disputes about the nature of the psyche are played out with unusual intensity. Jung himself furnishes the central paradox: he simultaneously insists that individual personality is recognizable from earliest infancy and that children, strictly speaking, ‘have no psychology of their own,’ being so thoroughly imbued with the parental atmosphere as to function as symptomatic expressions of parental complexes. Samuels documents this contradiction with precision, locating it across Jung’s filmed interviews and his introduction to Wickes. Papadopoulos elaborates the developmental implication: the child’s psyche is ‘largely contained in the parental psyche,’ undergoing a second, psychological birth only gradually. Against this containment model, Fordham’s developmental school — foregrounded by Samuels and Jacoby — advances a theory of primary selfhood expressed through deintegration and reintegration from the earliest weeks of life. Hillman, characteristically, reframes the entire developmental discourse, arguing that depth psychology’s child concept conflates the empirical child with the archetypal Child, and that the linear model of development — with regression as its shadow — distorts rather than illuminates psychic reality. Bowlby’s attachment tradition enters the corpus as an empirical counterweight, grounding claims about early relational damage in longitudinal research. The field is thus triangulated among Jungian ambivalence, post-Jungian developmental specificity, and empirical attachment science.
