The newborn baby itself sleeps more, most of the time in addition to eating milk, even sleep up to about 22 hours a day. However, if a newborn baby obviously appears to sleep more and eat less milk, we should pay attention to the possibility of hypoglycemia in newborns. For newborns, milk should be turned on after half an hour, and if breast milk is not secreted normally, a small amount of sugar water can be fed temporarily to prevent hypoglycemia from occurring. In addition, when there is cerebral hypoxia, sleepiness, little movement and no crying can also occur, so it is necessary to do cranial MRI and other related examinations in time and visit the neonatal unit if necessary.
