This chapter is concerned with the primal function of the skin of the baby and of its primal objects in relation to the most primitive binding together of parts of the personality not as yet differentiated from parts of the body. One year of observation of an immature young mother and her first baby showed a gradual improvement in the "skin-container" function up to twelve weeks. As the mother's tolerance to closeness to the baby increased, so did her need to excite the baby to manifestations of vitality lessen. In all patients with disturbed first-skin formation, severe disturbance of the feeding period is indicated by analytic reconstruction, though not always observed by the parents. Analytic investigation of the second skin phenomenon tends to produce transitory states of unintegration. Only an analysis which perseveres to thorough working-through of the primal dependence on the maternal object can strengthen this underlying fragility.
