Except for this one drawback, the forming of habits in the children is no laborious task, for the reward goes hand in hand with the labour; so much so, that it is like the laying out of a penny with the certainty of the immediate return of a pound. For a habit is a delight in itself; poor human nature is conscious of the ease that it is to repeat the doing of anything without effort; and, therefore, the formation of habit, the gradually lessening sense of effort in a given act, is pleasurable. This is one of the rocks that mothers sometimes split upon: they lose sight of the fact that a habit, even a good habit, becomes a real pleasure; and when the child has really formed the habit of doing a certain thing, his mother imagines that the effort is as great to him as at first, that it is virtue in him to go on making this effort, and that he deserves, by way of a reward, a little relaxation – she will let him break through the new habit a few times, and then go on again. But it is not going on; it is beginning again, and beginning in the face of obstacles. The ‘little relaxation’ she allowed her child meant the forming of another contrary habit, which must be overcome before the child gets back to where he was before.
As a matter of fact, this misguided sympathy on the part of mothers is the one thing that makes it a laborious undertaking to train a child in good habits; for it is the nature of the child to take to habits as kindly as the infant takes to his mother’s milk.
