Newborns sleep for a long time and with certain differences, so it is difficult to judge whether a newborn is sleepy from the sleep time alone. It is recommended to observe its mental state and milk consumption for preliminary judgment. Newborns usually sleep for more than 20 hours, i.e., they spend the whole day in sleep except for breastfeeding to ensure normal development. If the child is in good spirits, has a normal amount of milk and normal weight gain, there is no need to worry too much even if the sleep time exceeds the general standard. If the newborn is difficult to wake up in the sleep state or falls asleep immediately after waking up for a few seconds, it can be initially determined as narcolepsy. For example, if a newborn does not wake up after bouncing the soles of his feet 5 times during sleep, and if he does not eat milk, has abnormal spirit, or does not wake up after being called, he needs to be examined by the neonatal department in time. In short, the resistance of newborns is very poor, and parents need to take good care of them to prevent problems that cannot be solved in time, thus delaying their condition.
