Normal newborns sleep for 20-22 hours and are generally sleep-oriented. It wakes up only when hungry or urinating and defecating. Sleep time with full milk can usually last 1-3 hours.

Some disease states, in addition to waking up, can be accompanied by cyanosis, facial color change, cold hands and feet, skin flowering or skin darkening, pay attention to the appearance of infection and other conditions, suggesting that the condition is more serious, must go to the regular hospital for consultation.
