To determine if it is normal for a baby to have a bowel movement while eating milk, a comprehensive analysis is needed to target the situation. First, it is a normal phenomenon. In this case, the baby will have a bowel movement while eating milk, and there are no special uncomfortable symptoms in the abdomen, such as bloating, crying and vomiting. Second, it is caused by an abnormal disease, especially if the child has an intestinal disease. In this case, children with intestinal disorders, such as gastrointestinal disorders or irritable bowel syndrome, may also have the condition of relieving stools while eating milk, which is pathological and should be promptly adjusted.
