Jung explains the polymorphism of these phenomena as arising from a gradual movement of the libido from exclusive service in the function of nutrition into new avenues which successively open up with the development of the child until the final inauguration of the sexual function proper at puberty. Normally these childish bad habits are gradually relinquished until the libido is entirely withdrawn from these immature phases and with the ushering in of puberty for the first time “appears in the form of an undifferentiated sexual primitive power, clearly forcing the individual towards division, budding, etc.”
However, if in the course of its movement from the function of nutrition to the sexual function the libido is arrested or retarded at any phase, then a fixation may result, creating a disturbance in the harmony of the normal development. For, although the libido is retarded and remains clinging to some childish manifestation, time goes on and the physical growth of the child does not stand still. Soon a great contrast is created
