Mothers who get annoyed with an infant, who put it aside and say, "Well, let him cry for a time", considering other work more important, do not know what they are missing. Handling the child is the greatest opportunity. And even if they do it at the greatest sacrifice it is worth while; because once an infant is impressed with being neglected by the mother, there remains all its life an impression, in the deepest depth of its being, of a soreness; and when a person grows up he feels it unconsciously, and then he is displeased and dissatisfied with everybody he meets.
