If a newborn baby has overflowing milk, it is important to distinguish whether it is physiological or pathological. If your child has occasional milk spillage, is generally in good condition, does not have bloating, and has normal stools, consider that he or she has eaten too much milk and has gas or indigestion. If it is caused by indigestion, give your child probiotics. If the overflow is pathological, it will be more frequent, usually combined with abnormal abdominal distension or stool, and uneven weight gain. When a newborn baby has milk spillage, it is important to pay attention to safety and keep the baby in a side-lying position or with the head tilted to the side to avoid choking.
