It will be well, before doing so, to tell you how many motions a young infant ought to have a day, their color, consistence, and smell. Well, then, he should have from three to six motions in the twenty-four hours; the color ought to be a bright yellow, inclining to orange; the consistence should be that of thick gruel; indeed, his motion, if healthy, ought to be somewhat of the color (but a little more orange-tinted) and of the consistence of mustard made for the table; it should be nearly, if not quite, devoid of smell; it ought to have a faint and peculiar, but not a strong disagreeable odor. If it has a strong and disagreeable smell, the child is not well, and the case should be investigated, more especially if there be either curds or lumps in the motions; these latter symptoms denote that the food has not been properly digested. Now, suppose a child should have a slight bowel complaint—that is to say, that he has six or eight motions during the twenty-four hours,—and that the stools are of a thinner consistence than what I have described,—provided, at the same time, that he is not griped, that he has no pain, and has not lost his desire for the breast: What ought to be done? _Nothing._ A slight looseness of the bowels should _never_ be interfered with,—it is often an effort of nature to relieve itself of some vitiated motion that wanted a vent—or to act as a diversion, by relieving the irritation of the gums. Even if he be not cutting his teeth, he may be “breeding” them, that is to say, the teeth may be forming in his gums, and may cause almost as much irritation as though he were actually cutting them. Hence, you see the immense good a slight “looseness of the bowels” may cause. I think that I have now proved to you the danger of interfering in such a case, and that I have shown you the folly and the mischief of at once giving astringents—such as Godfrey’s Cordial, Dalby’s Carminative, etc.—to relieve a _slight_ relaxation. A moderate “looseness of the bowels,” then, is often a safety-valve, and you may with as much propriety close the safety-valve of a steam engine as stop a moderate “looseness of the bowels!” Now, if the infant, instead of having from three to six motions, should have more than double the latter number; if they be more watery; if they become slimy and green, or green in part and curdled; if they should have an unpleasant smell; if he be sick, cross, restless, fidgety, and poorly; if every time he has a motion he be griped and in pain, we should then say that he is laboring under diarrhœa; then, it will be necessary to give a little medicine, which I will indicate in a subsequent Conversation.
