Determining whether it is normal for a newborn to sleep for 5-6 hours a night needs to be analyzed on a case-by-case basis. First of all, it is normal. If the child can sleep for 5-6 hours, but the symptoms are better after waking up, the milk is normal, the child plays better, the weight gain is normal, and the urine and feces are better. This is normal because newborns sleep longer than older children. Parents do not need to worry too much about this situation. Secondly, it is an abnormal situation. If the child sleeps for more than 5-6 hours, and the child wakes up with poor mental state, or accompanied by other symptoms, such as coughing, vomiting, diarrhea and so on. This is considered to be due to respiratory tract infections, central nervous system infections, digestive tract infections and other diseases, we must give the child timely treatment, such as the application of cephalosporin anti-infection treatment.
