At a very early age children can comprehend what is plainly and simply told them, and, by kind and judicious management, can be taught to obey.... The mother should not allow her child to gain an advantage over her in a single instance; and, in order to maintain this authority, it is not necessary to resort to harsh measures; a firm, steady hand and a kindness which convinces the child of your love will accomplish the purpose. But let selfishness, anger, and self-will have their course for the first three years of a child’s life, and it will be hard to bring it to submit to wholesome discipline. Its disposition has become soured; it delights in having its own way; parental control is distasteful. These evil tendencies grow with its growth, until, in manhood, supreme selfishness and a lack of self-control place him at the mercy of the evils that run riot in our land.
