DOES MILK CURDLE IN THE STOMACH?
The moment milk enters the human stomach, the digestive fluids change it into curd. The cheesy part is separated from the whey, or watery part. We often hear mothers say when their infant vomits up curd, that their milk does not agree with it, that its stomach is sour and curdles the milk, and the curd is very hard. The truth is that the milk in the stomach always curdles before it digests. If it did not curdle, it would prove that the stomach was weak. Those infants who are fed at regular intervals are less apt to overfeed than those who are fed at irregular periods. We have found that infants nursed at intervals of two hours are much more apt to suffer from indigestion. Some mothers may ask, why is human milk more digestible than cow's ? The principal reasons are two : first, the amount of curd is greater in cow's milk ; and second, the curd is harder, i.e., the caseine from human milk is more porous, and is on this account more easily dissolved and digested.— Hearld of Health.
