The newborn’s nervous system is not well developed, and he or she sleeps for 20 hours a day. After 2-3 hours of sleep, the newborn will wake up to feed, and the waking time lasts 15-20 minutes, after which the newborn will enter the next sleep cycle. As the newborn’s age increases, the newborn’s sleep time will gradually shorten and the waking time will become longer and longer. The amount of milk for a newborn is usually between 10-30mL at birth, but if the child sleeps for a long period of time, wakes up for a shorter period of time and eats less milk. At this time, it is necessary to appropriately stimulate the child, gently massage the soles of the feet or stimulate the child’s earlobes to see how the child responds. If, after stimulation, the child still goes to sleep quickly and still does not feed well, this situation requires neonatology consultation.
