So far, almost all that has been written--and there has been a great deal of unavoidable repetition--has been devoted to an attempt to determine the causes which lead the child to refuse food and the methods which we adopt to prevent or overcome the difficulty. Other neuroses may be studied in less detail, because they depend for their existence upon the same causes. For example, the habit of refusing sleep, which is as common and almost as distressing as the habit of refusing food, depends both upon a perversion of suggestion and upon the phenomenon that we have called negativism. If struggling and crying has occurred upon a series of nights, the child comes to associate his bed not with sleep but with tears. If a mother values her peace of mind, if she would spare herself the discomfort of hearing her child sob himself nightly into uneasy sleep, she must be wary how this all-important event of going to bed is approached. With a nervous and restless child the preliminaries of preparing for bed must be managed carefully and tactfully. The hour before bedtime is almost universally the most interesting of the whole day for the child. Then the baby, with his best frock on, and books and toys, is the centre of interest in the drawing-room, till the clock strikes and the nurse appears at the door. Suddenly it is all over, and inexorable routine sends him off to bed. The good nurse will give the child a little time to recover from the shock of her arrival, and will not hurry him. She knows that his little mind is slow to act, and that he must be led gradually to face a new prospect. If she hurries him, catching him up in her arms from the midst of his unfinished pursuits, resistance and tears are almost sure to follow, and the difficult task of the day--the putting to bed--has made the worst possible start. When this has happened on one or two successive evenings, the habit of resistance to going to bed becomes fixed, and, like all bad habits, is difficult to break. A nurse who has a way with children will arouse his interest in a new pursuit, in which he can play the chief part, the putting away of his picture books and toys. If he is too small to carry his own chair or table to its allotted place in the room, at least he can show his learning by pointing out the spot. In the waving of good-byes he is expert and takes a legitimate pride, and upstairs he has learnt that there are new delights. He himself can turn on the taps in the bathroom, and he can set every article in the proper place ready for use. All children love their bath, and if interest and good temper has been so far preserved, without a break, it will be ill-fortune if even the drying process is not carried off without a hitch. Afterwards, for a little, nervous babies, whose brains still teem with all the excitements of the day, are best left to sit for a few moments by the nursery fire, while the nurse puts all the garments one by one to bed.
