What is the cause of foam in baby stool?

Foamy stools may be caused by breathing in a lot of air when the baby is crying, and a lot of gas produced by bacterial fermentation of food in the intestine. It may also be caused by intestinal inflammation in the abdomen. Common care is to massage the abdomen and promote intestinal motility, or even oral probiotics to regulate the intestine. If the symptoms do not improve, it is necessary to go to the hospital for diagnosis and treatment.
