Newborn babies sleep on eating is a normal phenomenon, newborn babies sleep about 20-22 hours a day, in addition to pulling, urine, feel uncomfortable waking up to change diapers, hungry, wake up to eat milk, the rest of the time are sleeping, some are sleeping while eating milk. Because the newborn’s cerebral cortex is not yet mature, when waking up during the day due to various stimuli in the surrounding environment, the nerve cells in the brain will feel fatigue, so the excitability of the cerebral cortex is reduced and enter a sleep state. Newborns spend most of their time sleeping not only to relieve the fatigue of brain nerve cells, but also to promote better development of brain cells and all aspects of the body, to ensure sufficient sleep time and quality sleep, can promote the development of the body systems. Therefore, newborns spend almost all of their time sleeping, except for breastfeeding, and as they develop, their sleep time will gradually shorten.
