More frequently than this, especially in the case of children who are born before the time, the opening through which the navel string passes is large at birth, and fails to close as speedily and completely as it should do afterwards. When everything goes on as it ought, the gradual contraction of the opening helps to bring about the separation of the navel string and its detachment, and the perfect closure of the opening takes place at the same time, between the fifth and the eighth day after birth.
If this does not occur, the bowels are very apt to protrude through the opening, and if allowed to do so for weeks or months, the opening becomes so dilated that its closure is impossible, and the child grows up afflicted permanently with rupture through the navel. This is always an inconvenience, sometimes even a source of serious danger; but if means are taken to prevent the condition becoming worse, nature seldom fails eventually to bring about a cure, and to effect the complete closure of the opening.
If the muscles on either side do not come into apposition, but leave a cleft between them, the infant should constantly wear a broad bandage of fine flannel round the stomach, not applied too tightly, in order to give support. The circular bandages of vulcanised india-rubber with a pad in the centre are nowise to be recommended. The pad is apt to become displaced, and to press anywhere but over the navel, while its edges irritate the infant's delicate skin, and the pressure which it exerts if it is sufficiently tight to retain its place interferes with respiration.
A pad composed of pieces of plaster spread on wash-leather, and of graduated sizes and kept in place by adhesive strapping,7 answers the purpose of preventing the protrusion at the navel, and of thus facilitating the closure of the ring better than any other device with which I am acquainted. They need, however, to be continued even for two or three years, and though they should have been left off it is wise to resume their use if the child should be attacked by whooping-cough, diarrhœa, or any other ailment likely to occasion violent straining.
CHAPTER V.
ON THE DISORDERS AND DISEASES OF CHILDREN AFTER THE FIRST MONTH, AND UNTIL TEETHING IS FINISHED
Infantile Atrophy.—In by far the greater number of instances, the wasting of young children is due to their being fed upon food which they cannot digest, or which when digested fails to yield them proper nourishment. I quoted some figures in my introductory remarks, to show from the evidence obtained at Berlin how much larger was the proportion of deaths under the age of one year among hand-fed infants than among those brought up at the breast. Foundling hospitals on the Continent, in which the children are all drawn from the same class, and subjected in all respects to a similar treatment, except that in some they are fed at the breast, in others brought up by hand, show a mortality in the latter case exactly double of that in the former.
It is as idle to ignore these facts, and to adduce in their disproof the case of some child brought up most successfully by hand, as it would be to deny that a battle-field was a place of danger because some people had been present there and had come away unwounded.
But it is always well not merely to accept a fact, but also to know the reason why a thing is so. The reason is twofold: partly because the different substitutes for the mother's milk, taken for the most part from the vegetable kingdom, are less easy of digestion than the milk, and partly because, even were they digested with the same facility, they do not furnish the elements necessary to support life in due proportion.
All food has to answer two distinct purposes: the one to furnish materials for the growth of the body, the other to afford matter for the maintenance of its temperature; and life cannot be supported except on a diet in which the elements of nutrition and those of respiration bear a certain proportion to each other. Now, in milk, the proper food of infants, the elements of the former are to those of the latter about in the proportion of 1 to 2, while in arrowroot, sago, and tapioca they are only as 1 to 26, and in wheaten flour only as 1 to 7. If to this we add the absence in these substances of the oleaginous matters which the milk contributes to supply the body with fat, and the smaller quantity, and to a certain extent the different kind, of the salts which they contain, it becomes apparent that by such a diet the health if not the life of the infant must almost inevitably be sacrificed.
But these substances are not only less nutritious, they are also less easy of digestion than the infant's natural food. We all know how complex is the digestive apparatus of the herbivorous animal, of which the four stomachs of the ruminants are an instance, and how large is the bulk of food in proportion to his size which the elephant requires, compared with that which suffices for the lion or the tiger.
The stomach of the infant is the simple stomach of the carnivorous animal, intended for food which shall not need to stay long in that receptacle, but shall be speedily digested; and it is only as the child grows older, and takes more varied food, that the stomach alters somewhat in form, that it assumes a more rounded shape, resembling somewhat that of the herbivorous animal, and suited to retain the food longer. The young of all creatures live upon their mother for a certain time after birth; but in all the preparation for a different kind of food, and with it for an independent existence, begins much sooner and goes on more rapidly than in man. Young rabbits are always provided with two teeth when born, and the others make their appearance within ten days. In the different ruminants the teeth have either begun to appear before birth, or they show themselves a few days afterwards; and in either case dentition is completed within the first month, and in dogs and cats within the first ten weeks of existence.
In the human subject the process of teething begins late, between the seventh and the ninth month, and goes on slowly: the first grinding teeth are seldom cut before the beginning of the second year, and teething is not finished until after its end. Until teething has begun the child ought to live exclusively on the food which nature provides; for until that time the internal organs have not become fitted to digest other sustenance, and the infant deprived of this too often languishes and dies. To get from other food the necessary amount of nourishment, that food has to be taken in larger quantities, and, from the difficulty in digesting it, needs to remain longer in the stomach than the mother's milk. One of the results of the indigestibility of the food is that the child is often sick, the stomach getting rid of a part of that food which it is unable to turn to any useful purpose; and so far well. But the innutritious substances do not relieve the sense of hunger. The child cries in discomfort, and more is given to it, and by degrees the over-distended stomach becomes permanently dilated, and holds a larger quantity than it was originally meant to contain. The undigested mass passes into a state of fermentation, and the infant's breath becomes sour and offensive, it suffers from wind and acid eructations, and nurses sometimes express surprise that the child does not thrive since it is always hungry. While some of the food is got rid of by vomiting, some passes into the intestines, and there becomes putrid, as the horribly offensive evacuations prove. They come away, large and solid and white, for the secretion of the bile is inadequate to complete that second digestion which should take place in the intestines; or else the irritation which they excite occasions diarrhœa—a green putty-like matter comes away mixed with a profuse watery discharge.
What wonder is it that in such circumstances the body should waste most rapidly; for it is forced from its own tissues to supply those elements essential to the maintenance of life, which its food contains in far too scanty a proportion. Every organ of the body contributes to the general support, and life is thus prolonged, if no kind disease curtail it, until each member has furnished all that it can spare, and then death takes place from starvation, its approach having been slower, but the suffering which preceded it not therefore less, than if all food had been withheld.
Do not suppose that in this description I have been painting too dark a picture, or that children who die thus have been exceptionally weak, and so under the acknowledged difficulties of hand-feeding at length became consumptive. They do not die of consumption, and in a large number of instances their bodies show no trace of consumptive disease, but present appearances characteristic of this condition of starvation, and of this only.
Along the whole track of the stomach and intestines are the signs of irritation and inflammation. The glands of the bowels are enlarged, actual ulceration of the stomach is often met with; while so far-reaching is the influence of this
