In most cases, it is useless to drink water after an infant has indigestion. Indigestion in infants is caused by poor spleen and stomach function, and it is more likely to occur when infants eat too much food, such as too much milk or too much meat. Infants with indigestion may experience vomiting, abdominal pain, and undigested food or milk flaps in the stool. It is necessary to give the infant medication to eliminate food and stagnation, such as Bao He Wan or Wang’s Bao Chi Wan. Giving water to infants only helps the stool to flow smoothly and is very poor at relieving indigestion. In summary, it is basically useless to drink water for infants with indigestion.
