"Serious mischief is frequently done by the mother attempting to remedy every temporary diminution of milk, by increasing the quantity of her food, or by imagining that some stimulating drink will answer this valuable end. Owing to some trifling disturbance in the system of a temporary kind, the secretion of milk may be for the moment suspended or diminished. An attempt is made to recall it by an increase of food, by which a slight inconvenience is converted into a permanent derangement of the system, or a fever of even a dangerous character may be generated; or owing to a false theory, or imperfect observation, it has been supposed that certain liquors have a control over the secretion of milk, and hence the too free use of certain combinations, into which ardent or fermented spirits too largely enter. We must not, however, be supposed to deny the influence of certain solid as well as fluid substances upon the secretion of milk, for we well know, that unless the body be properly supported, there must soon be a diminution of milk. We only mean to insist that it is the nutritious, and not the stimulating part of the diet, which is subservient to the plentiful and healthful formation of this fluid. In proof of this we need only observe, that we have often been consulted upon the subject of the failure of milk, where an anxious mother herself, or a hireling nurse, was concerned, and had been informed by them that they had tried every thing with a hope of improving it, such as rich food, porter, ale, beer, &c. without success, or it was followed, perhaps, by a diminution of it. In such cases we have often succeeded in producing a plentiful supply of milk, by adopting the opposite plan of treatment, for it must be borne in mind, as an important truth, that this failure proceeds more frequently from an over, than from an under, quantity of food or of drink. It is a fact well-known to all who have paid attention to the consequences of arterial excitement, that when it amounts to even moderate fever, the milk almost immediately diminishes in quantity; and also when this action is diminished by suitable remedies (provided it has not continued too long,) that the secretion of milk again becomes more abundant. Upon this principle we have frequently prescribed evacuants and abstinence to promote the secretion of milk." (Dewees, _on Children_.)
