If infants love abdominal exhaust (farting), it is mainly due to the following reasons: first, due to intestinal flora disorders, intestinal flora balance will cause abnormal intestinal peristalsis, resulting in more abdominal exhaust, and cause abdominal distension, and even crying and restlessness and other symptoms. Secondly, the symptoms caused by indigestion, the baby’s diet is mainly based on milk, if the amount of milk exceeds the digestive capacity, it will cause indigestion, and then cause more abdominal exhaust, and even undigested milk flaps in the stool, etc.
