_Nux Vomica, 3d._--Constipation or undigested curds of milk in the feces. Child starts in its sleep, has short naps and throws its head back when it cries. To one grain add six tea-spoons of warm water, and give every ten minutes in half tea-spoonful doses. For colic of children and grown people, I have found more frequent relief from this remedy than all others. It promotes digestion, equalizes the circulation and feeds the nervous system. The nursing mother should also take it once or twice a day when the child has these symptoms, and an occasional dose taken by both, prevents subsequent attacks. She must remember, too, to take sufficient rest and sleep, using every means to promote her own best health. CONSTIPATION is not a very frequent ailment of infants, but is occasionally met with, and sometimes becomes very obstinate. When a nursing child is thus affected, the mother will usually be found to be suffering from the same conditions. In such a case, she should follow the directions in Chap. V, and through correct habits in her own system, she will doubtless find the child relieved. Want of regularity in its habits often produces costiveness in an infant. If he is fed or nursed regularly, and held out at the same time of each day, and as he gets older is put upon a chair, he will seldom be troubled with this complaint. It is wonderful how soon the bowels in most cases, by this simple plan, may be brought into a regular habit. _A soap suppository_ should be used after a day or two, if this method fails. This is a safe, speedy and certain method of moving the bowels. Make it by paring a piece of white castile soap round. Should be about the size of a lead-pencil, pointed at the end, and two inches in length. Moisten in warm water and introduce nearly the whole length. After remaining from one to five minutes it will be expelled and the bowels will be comfortably and effectually relieved. If the feces are very hard, like little balls, it is better to give an enema of castile soapsuds, to one cupful of which, one tea-spoonful of sweet oil has been added. Squeezing cold or tepid water over the child’s bowels, followed by hand friction, aids to stimulate them to action. Some advise rubbing the bowels with castor oil, getting thereby the aperient effect, without the irritation of an internal dose. Do not begin by giving a little baby aperient drugs. Chevasse says: “If you once begin, and continue it for a while, opening medicine becomes a dire necessity, and then woe betide the poor unfortunate child.” Purgative medicines irritate beyond measure the tender organs of an infant and ordinarily result in constipation. DIARRHEA of infants is nature’s first method of removing obstructions and overcoming derangements of the system, and in nine cases out of ten should not be interfered with.
