Geleerd discusses the importance of the mother's adjustment, feeding, weaning and toilet training. She establishes the following five general rules: (1)

Infants need a certain amount of their mother's love just as much as they need vitamins and calcium. (2) The relationship between the mother or the nurse and the child is fundamental in determining all later relationships. (3) Self-control develops slowly and one must not demand it of the child until he is physically and psychologically ready. (4) All changes in routine should be made gradually and in periods of comparative freedom from stress. (5) Each infant has his own peculiarities or individuality and taste which must be studied carefully and intelligently so that the routines fit the baby and not the baby the routines.
