A newborn baby, usually referred to as a neonate, is an infant who has not yet reached the period of 28 days after birth, and whose sleep time of about 18~20 hours per day is considered normal, but there are individual variations. Newborns spend most of their time in sleep, usually about 18 to 20 hours a day. Each sleep time is about 1~4 hours with 1~2 hours of awakening, but some babies sleep for more than 6 hours each time, and usually the daytime sleep time and nighttime sleep time are equal. The sleep time of newborn babies varies greatly among individuals, but if the baby eats milk normally, has a good spirit and grows up to the standard, it can be considered as normal. However, if the baby’s sleep time is too short, accompanied by crying and restlessness, or if the sleep time is too long and difficult to wake up, it is recommended to consult a doctor in time to rule out pathological factors. If necessary, timely treatment.
