From the first moment the infant is applied to the breast, it must be nursed upon a certain plan. This is necessary to the well-doing of the child, and will contribute essentially to preserve the health of the parent, who will thus be rendered a good nurse, and her duty at the same time will become a pleasure.
This implies, however, a careful attention on the part of the mother to her own health; for that of her child is essentially dependent upon it. Healthy, nourishing, and digestible milk can be procured only from a healthy parent; and it is against common sense to expect that, if a mother impairs her health and digestion by improper diet, neglect of exercise, and impure air, she can, nevertheless, provide as wholesome and uncontaminated a fluid for her child, as if she were diligently attentive to these important points. Every instance of indisposition in the nurse is liable to affect the infant.
