The normal sleep time for newborns is usually 16-22 hours. As the newborn develops, the sleep time will gradually decrease. Neonatal narcolepsy and normal sleep can be distinguished from developmental conditions, the ability to wake up, and accompanying symptoms: 1. Developmental conditions: If a newborn has been playing or eating irregularly for a long time, resulting in increased sleep time the next day, this is generally normal. If the sleep time is too long for unknown reasons, it is possible that the newborn is drowsy due to disease. Generally speaking, the normal development of newborns and good sleep state can exclude disease factors, while the prolonged sleep time caused by disease usually leads to developmental abnormalities; 2, can wake up: newborns in normal sleep, relatively easy to be affected by the external environment. However, if the newborn is drowsy it is not easy to be woken up, or wake up indifferent; 3. Accompanying symptoms: normal newborns should develop normally with adequate sleep and eat well. If the newborn sleeps continuously for a long time and is not easily awakened and accompanied by different degrees of fever or other symptoms, such as poor diet and digestion, poor mental state, irritability and crying, then you should be alert to whether the drowsiness is caused by disease. In case of abnormalities, you should seek medical attention and improve blood tests to clarify the cause and then treat the symptoms under the guidance of the doctor.
