A nurse ought to be both strong and active, in order that her little charge may have plenty of good nursing; for it requires great strength in the arms to carry a heavy child for the space of an hour or two at a stretch, in the open air; and such is absolutely necessary, and is the only way to make him strong, and to cause him to cut his teeth easily, and at the same time to regulate his bowels; a noise, therefore, most be strong and active, and not mind hard, work, for hard work it is; but, after she is accustomed to it, pleasant notwithstanding. Never should a nurse be allowed to wear a mask, nor to dress up and paint herself as a ghost, or as any other frightful object. A child is naturally timid and full of fears, and what would not make the slightest impression upon a grown-up person might throw a child into fits-- "The sleeping, and the dead, Are but as pictures: 'tis the age of childhood That fears a painted devil."--_Shakspeare_. Never should she be permitted to tell her little charge frightful stories of ghosts and hobgoblins; if this be allowed, the child's disposition will become timid and wavering, and may continue so for the remainder of his life. If a little fellow were not terrified by such stories, the darkness would not frighten him more than the light. Moreover, the mind thus filled with fear, acts upon the body, and injures the health. A child must never be placed in a dark cellar, nor frightened by tales of rats, &c. Instances are related of fear thus induced impairing the intellect for life; and there are numerous examples of sudden fright causing a dangerous and even a fatal illness. _Night-terrors_.--This frightening of a child by a silly nurse frequently brings on night-terrors. He wakes up suddenly, soon after going to sleep, frightened and terrified; screaming violently, and declaring that he has seen either some ghost, or thief, or some object that the silly nurse had been previously in the day describing, who is come for him to take him away. The little fellow is the very picture of terror and alarm; he hides his face in his mother's bosom, the perspiration streams down him, and it is some time before he can be pacified--when, at length, he falls into a troubled feverish slumber, to awake in the morning unrefreshed. Night after night these terrors harass him, until his health materially suffers, and his young life becomes miserable looking forward with dread to the approach of darkness.
