Montagu describes an infant, three months of age, who accepted a sudden change from breast to bottle feeding without any obvious immediate disturbance, an observation which can be easily duplicated by any pediatrician. He, however, is of the opinion that observations of this kind disprove the 'psychoanalytic hypothesis of a trauma of weaning'. He quotes a paper by Melanie Klein according to which early Oedipus tendencies are released in consequence of the frustration of weaning. But Melanie Klein also knows that the early infant prefers the bottle to the breast because it is so much easier for the child to get the desired food that way. A negative reaction to weaning develops only after the child has developed a relationship to the mother that is more important to him than his desire for quick nourishment, which does not happen within the first three months. In Montagu's infant the love for food has not yet been substituted by the love for the mother. That weaning at a later age is often rejected by the child is even described in the average textbooks of pediatrics.
