Do not allow a child to form such habits, that it will not be quiet, unless tended and amused. A healthy child should be accustomed to lie or sit in its cradle, much of the time; but it should occasionally be taken up, and tossed, or carried about, for exercise and amusement. An infant should be encouraged to _creep_, as an exercise very strengthening and useful. If the mother fears the soiling of its nice dresses, she can keep a long slip or apron, which will entirely cover the dress, and can be removed, when the child is taken in the arms. A child should not be allowed, when quite young, to bear its weight on its feet, very long at a time, as this tends to weaken and distort the limbs. Many mothers, with a little painstaking, succeed in putting their infants, while awake, into their cradle, at regular hours, for sleep, and induce regularity in other habits, which saves much trouble. In doing this, a child may cry, at first, a great deal; but for a healthy child, this use of the lungs does no harm, and tends rather to strengthen, than to injure, them. A child who is trained to lie or sit, and amuse itself, is happier than one who is carried and tended a great deal, and thus rendered restless and uneasy when not so indulged. CHAPTER XX. ON THE MANAGEMENT OF YOUNG CHILDREN. In regard to the physical education of children, Dr. Clarke, Physician in Ordinary to the Queen of England, expresses views, on one point, in which most physicians would coincide. He says, "There is no greater error in the management of children, than that of giving them animal diet very early. By persevering in the use of an overstimulating diet, the digestive organs become irritated, and the various secretions, immediately connected with, and necessary to, digestion, are diminished, especially the _biliary secretion_. Children, so fed, become very liable to attacks of fever, and of inflammation, affecting, particularly, the mucous membranes; and measles, and the other diseases incident to childhood, are generally severe in their attack." There are some popular notions on the subject of the use of animal food, which need to be corrected. One mistake, is, in supposing that the formation of the human teeth and stomach indicate that man was designed to feed on flesh. Linnaeus says, that the organization of man, when compared with other animals, shows, that "fruits and esculent vegetables constitute his most suitable food." Baron Cuvier, the highest authority on comparative anatomy, says, "the natural food of man, _judging from his structure_, appears to consist of fruits, roots, and other succulent parts of vegetables."
