The great cause of the ill humor of children is the care which is taken either to quiet or to aggravate them. They will sometimes cry for an hour for no other reason in the world than because they perceive we would not have them. So long as we take notice of their crying, so long have they a reason for continuing to cry; but they will soon give over of themselves when they see no notice is taken of them; for, old or young, nobody loves to throw away his trouble. This is exactly the case with my eldest boy, who was once the most peevish little bawler, stunning the whole house with his cries; whereas now you can hardly hear there is a child in the house. He cries, indeed, when he is in pain; but then it is the voice of nature, which should never be restrained; and he is again hushed as soon as ever the pain is over. For this reason I pay great attention to his tears, as I am certain he never sheds them for nothing; and hence I have gained the advantage of being certain when he is in pain and when not; when he is well and when sick; an advantage which is lost with those who cry out of mere humor and only in order to be appeased. I must confess, however, that this management is not to be expected from nurses and governesses; for as nothing is more tiresome than to hear a child cry, and as these good women think of nothing but the time present, they do not foresee that by quieting it to-day it will cry the more to-morrow. But, what is still worse, this indulgence produces an obstinacy which is of more consequence as the child grows up. The very cause that makes it a squaller at three years of age will make it stubborn and refractory at twelve, quarrelsome at twenty, imperious and insolent at thirty, and insupportable all its life.
