Excessive breastfeeding usually causes abnormal stools, anorexia and frequent spitting up. 1. Abnormal bowel movements: Overfeeding may cause indigestion in the child, which may result in the presence of milk petals in the stool and increased frequency of bowel movements. 2. Anorexia: If the child is overfed, it may lead to premature anorexia and a lack of desire for milk. 3. Frequent spitting up: Because the child is still relatively young, the gastrointestinal function is weak and the stomach content is small, if the child is breastfed excessively, it may increase the chances of frequent spitting up. If the above symptoms are not relieved after lifestyle modification, you should consult a doctor in time to clarify the cause of the disease and treat it under the guidance of the doctor.
