When a newborn baby is drowsy and does not eat milk, it is mainly considered to be caused by the following reasons: 1. It is a physiological phenomenon. If the child is drowsy and does not eat milk, but is in a good state of mind, it is often due to too much milk in the past, resulting in indigestion, which is a physiological situation, and parents can continue to observe. If the child is in good spirits and plays normally, and only temporarily appears drowsy and does not eat milk, it will generally recover slowly. 2, due to pathological reasons. If your child has neonatal epidemic meningitis, he or she will become drowsy and not eat milk, and should be treated promptly with anti-infection treatment, otherwise it will cause brain damage. 3. Severe sepsis and other conditions may occur. In addition to lethargy and not eating milk, the child will often have high white blood cells in laboratory tests, and blood cultures will also culture bacteria, requiring timely anti-infection treatment for the child.
