The normal stool of a normal nursing infant is about the color of the yolk of an egg, and may be slightly green. The average amount is about two ounces daily. The stools should never be watery, but of a butter-like consistency. During the first few weeks the infant’s bowels will move on an average of four times daily. After about six weeks the average will be two a day. The stool changes in character as soon as the child is placed upon a mixed diet. It then becomes more like that of an adult but remains softer. Constipation is one of the most common incoördinations of infancy and childhood. There are many factors to be considered and many things that contribute to the condition. In older children habit plays no small part in aggravating constipation. For this reason the child should be very carefully trained early in life to obey the first call on Nature in this respect. Normally the infant should have two bowel movements a day, although some have more while others may have only one. Frequent movements do not, however, mean that the child is not constipated or costive. With two or three dry hard stools per day the child would be costive. Constipation is the result of a lack of motor function in the muscular walls of the intestines while costiveness is the result of a lack of secretion due to interference with transmission of secretory mental impulses. The two conditions are often associated. When there is a lack of motor function in the muscular walls the fecal matter will not be forced out of the intestinal tract fast enough and much of the moisture will be absorbed, thus leaving the fecal matter dry and hard. This is not a true costiveness and should not be mistaken for such. In costiveness there may be colicky pains which may be increased, and may at times be quite severe, when the hard dry fecal matter is passed. The general health of the child may be seemingly normal. In severe cases hemorrhoids and even hernia may be developed from the constant straining. Major Adjustment These cases are simple and respond readily to chiropractic adjustments. The combination varies somewhat in different cases. In constipation the major will be a lumbar vertebra. In costiveness, where secretions are involved, the combination will include a Li.P. and K. P. In some cases excellent results are obtained by adjusting ninth dorsal. INTUSSUSCEPTION Intussusception is a condition wherein there is a telescoping of the intestines in which one portion passes into the adjacent portion and produces an obstruction. This condition occurs most often in early infancy, although not very commonly. The most frequent site is at the ileocecal valve. It may, however, occur at any point in the intestinal tract. When it occurs in the small intestine it is known as enteric intussusception; in the colon as colic; and at the ileocecal valve as ilecocecal.
