The newborn baby itself sleeps more, but can cry and feed normally when hungry, and fall asleep again after feeding. When sleeping more, it is important to pay attention to the possibility of pathological disorders, such as hypoglycemia, poor feeding, less crying and less movement, and promptly go to the hospital for blood glucose monitoring, because the persistence of hypoglycemia can lead to brain damage, which can affect vision, hearing and even intelligence. If there is hypoxic-ischemic encephalopathy in the perinatal period, the baby is also prone to suppression, resulting in more sleeping and less crying.
