The importance of Regularity in infant education is beginning to be pretty generally acknowledged. The young mother knows that she must put her baby to bed at a proper time, regardless of his cries, even if she leave him to cry two or three times, in order that, for the rest of his baby life, he may put himself sweetly to sleep in the dark without protest. But a good deal of nonsense is talked about the reason of the child’s cries: he is supposed to want his mother or his nurse, or his bottle, or the light, and to be ‘a knowing little fellow,’ according to his nurse, quite up to the fact that if he cries for these things he will get them.
