As suggested above, frequency of sessions and aims of child psychoanalysis, (that is, to help the child work through the anxieties, fixations, and inhibitions that hindered development) were points of accord between Anna Freud and Melanie Klein. Holder also shows how Anna Freud was most likely influenced by Melanie Klein (for example, by eliminating the introductory phase of the analysis for a child, and realizing the value of play as a means for understanding the child). However they appear to diverge significantly in crucial ways. Melanie Klein, for example, thought that child psychoanalysis could be helpful for all children as an aid in the modulation of their anxieties, while Anna Freud felt that analysis is only appropriate when a child had developed an infantile neurosis. Interestingly, earlier in her work, Anna Freud felt that psychoanalytic principles could be incorporated prophylactically into child rearing, but later concluded this was overly optimistic.
