To the infant at the breast. At the period of weaning. And to the infant brought up by hand. 1. TO THE INFANT AT THE BREAST. UNHEALTHY MILK.--The infant's stomach and bowels may become deranged from the breast-milk becoming unwholesome. This may arise from the parent getting out of health, a circumstance which will be so manifest to herself, and to those more immediately interested in her welfare, that it is only necessary just to allude to it here. Suffice it to say, that there are many causes of a general kind to which it may owe its origin; but that the most frequent is undue lactation, a subject to which reference has already been made, and the effects both upon mother and child fully dwelt upon.[FN#31] To cure derangement of the bowels from this cause, a wet-nurse is the only remedy. [FN#31] See page 15. Anxiety of mind in the mother will cause her milk to be unhealthy in its character, and deficient in quantity, giving rise to flatulence, griping, and sometimes even convulsions in the infant.[FN#32] A fit of passion in the nurse will frequently be followed by a fit of bowel complain in the child.[FN#33] These causes of course are temporary, and when removed the milk becomes a healthy and sufficient for the child as before. [FN#32] See page 25. [FN#33] See page 33. Sudden and great mental disturbance, however, will occasionally drive away the milk altogether, and in a few hours. A Mrs. S., aet. 21, a fine healthy woman, of a blonde complexion, was confined of a boy in October, 1836. She had a good time, and a plentiful supply of milk for the child, which she continued to suckle till the following January, a period of three months, when her milk suddenly disappeared. This circumstance puzzled the medical attendant, for he could not trace it to any physical ailment; but the milk never returned, and a wet-nurse became necessary. In the following spring the husband of this lady failed, an adversity which had been impending since the date when the breast-milk disappeared, upon which day the deranged state of the husband's affairs was made known to the wife,--a fact which at once explained the mysterious disappearance of the milk.
