The proper methods of combating a tendency to over-abundance or to scantiness of milk have been alluded to. Medicines, unless prescribed by the medical attendant, should rarely or never be taken during this period, as many of them enter the milk and may thus affect the child. RELATIONS OF HUSBAND AND WIFE DURING NURSING. After a natural and healthful confinement, the nurse usually remains with the mother for a period of four weeks. During the whole of this time the husband should occupy a separate apartment, and, according to some physicians, this separation should be protracted during the entire period of nursing. But this is unusual, and in most cases unnecessary. Only those women who are warned by the recurrence of their monthly illness that they are liable to another pregnancy immediately, should insist on such an ascetic rule as this. Unquestionably the quality of the milk is much deteriorated by a conception; and therefore, both in the interest of the mother and child, the husband should renounce his usual privileges at such times. Most women do not have their periodical illness, and consequently are not liable to a second pregnancy, before seven months have elapsed after childbirth. There are, however, numerous exceptions to this rule, and it is impossible to foretell who will and who will not be the exception. Moreover, as any excitement of the passions alters to some extent the secretion of the breasts, often to the injury of the child, it is every way advisable that great temperance be exercised in all cases in the marital relations at these epochs. SIGNS OF OVER-NURSING. The symptoms of over-nursing may be enumerated as follows:--Aching pain in the back; often, pain across the shoulders, and on the top of the head or forehead; marked paleness of the face; inability to sleep; frightful dreams when sleep does come; great debility; extreme depression of the spirits; disorders of the sight, and mental disturbances, which take on the form of melancholia, the delusions relating mostly to subjects of a religious character, to the effect that the unpardonable sin has been committed, and the like. The headache is situated on the top of the head, and this spot may be noticed to be perceptibly hotter to the touch than other parts of the head. These symptoms indicate that the process of nursing is making too great a drain upon the system.
