Normally, newborns sleep about 20 hours a day.
Because the neural synapses of the newborn’s brain are fewer, the nerve impulses caused by various stimuli have a slower conduction speed, and the excitability of the cerebral cortex is low, so the newborn sleeps for a long time, about 20 hours a day. Adequate sleep plays a very important role in promoting the development of the central nervous system and physical growth and development.
As the age of the month increases and the development of the nervous system is perfected, the sleep time of newborns will gradually decrease. Parents can gradually make their children develop a sleep routine by interacting more with their babies during the day and taking a long sleep at night to establish a sleep cycle. At the same time, it is necessary to observe the sleep situation, whether there are cases of poor sleep, easy to wake up and crying, which affect the growth and development.
If the newborn sleeps too long or too short than usual, it is recommended to go to the hospital in time.
