By a mode of investigation like this, any defect or error in the dietetic management of the infant producing the disorder will be easily detected by a careful mother; and its correction alone will, in very many instances, be all that is necessary to remove the symptoms.

For example, if flatulence and griping, followed by diarrhoea, occur to an infant at the breast; if at the same time it becomes pale, its flesh flabby, its disposition fretful, always crying until it is put to the breast, the nipple of which it grasps eagerly, sucking eagerly, yet never satisfied, for its hunger continues, it is not nourished; if, too, the more it sucks, the more the stomach and bowels are deranged, the more it vomits and is purged; depend upon it the cause of all the evil will be found to be unwholesome milk.  No medicine will avail any thing here; the cause must be removed; the best medicine, and the only remedy, is a breast of healthy milk.  And if this is not procured early, there will be great danger of a diarrhoea setting in, which may probably prove fatal to the child.

Again; if there is simply vomiting of the breast-milk almost immediately after the child has been suckled, the milk coming up pure and unchanged, and discharged without any apparent effort, and the moment after the child is cheerful and happy, this will be found to depend upon repletion, and not upon unwholesome milk; in fact, the stomach has received too much.  This must be prevented in future, not by giving medicine, but simply by removing the infant from the nipple immediately it ceases to draw strongly, the moment it begins to dally with the breast.

Again; if flatulence and griping occur to the child brought up by handy this derangement will generally be found to result from overfeeding:  abstinence and diminution of the quantity of the food will generally be all that is necessary here.  It will be well, however, for the mother in this case, and she may do it with the utmost safety, to unload the bowels of their indigestible contents by the exhibition of a tea-spoonful of castor oil.  A dose or two of this medicine will effectually clear them out, without increasing the irritation, or weakening the child, whilst it will in most instances altogether remove the symptoms.  If the flatulence, however, should continue, four or five grains of magnesia may be mixed with the last meal at night, and a little warm water thrown up into the bowel as an injection the next morning.

Diarrhoea occurring in a child brought up by hand, if it be not the result of overfeeding, will very frequently be found to arise from unsuitable diet, the food given not being of a kind suited to the infant’s stomach; for what will agree with one child often disagrees with another.  Alteration of diet will sometimes alone suffice in these cases to cure, if this alteration is only made early enough, before any considerable irritation of the stomach and bowels has been induced.
