A child is a growing plant and it needs not only bodily nourishment, but also the nourishment of the heart; and that is best taught by loving the child and by reciprocating its love. And yet it must be taught balance, to keep its emotion within certain bounds and limitations. A child must be taught the use of love through the expression of sweetness in its thought, speech, and action. A wrongly given love spoils the child by making it rude, vain, and indifferent. One must not show all one's love to one's children, especially not in any emotional form. One must have a certain amount of reserve in one's own self, for the child to take example by and to follow. An excessive amount of reserve may imply want of love, which is fruitless at times; a balance of love and reserve in dealing with a child is the right thing.
