Here we approach very near to the heart of the subject. Stripped of all that is not essential we see the problem of the management of children reduced to the interplay between the adult mind and the mind of the receptive suggestible child. That which is thought of and feared for the child, that he rapidly becomes. Placid, comfortable people who do not worry about their children find their children sensible and easy to manage. Parents who take a pride in the daring and naughty pranks of their children unconsciously convey the suggestion to their minds that such conduct is characteristic of them. Nervous and apprehensive parents who are distressed when the child refuses to eat or to sleep, and who worry all day long over possible sources of danger to him, are forced to watch their child acquire a reputation for nervousness, which, as always, is passively accepted and consistently acted up to. Differences in type, determined by hereditary factors, no doubt, exist and are often strongly marked. Yet it is not untrue to say that variations in children, dependent upon heredity, show chiefly in the relative susceptibility or insusceptibility of the child to the influences of environment and management. It is no easy task to distinguish between the nervous child and the child of the nervous mother, between the child who inherits an unusually sensitive nervous system and the child who is nervous only because he breathes constantly an atmosphere charged with doubt and anxiety.
