To determine whether it is normal for a newborn to cry or not, we need to analyze the newborn according to its systemic symptoms, as follows: 1, normal: if the newborn does not cry or fuss, but the mental state is better, the amount of milk eaten is normal, the weight gain is comparable to that of children of the same age, this is because the parents of the newborn care very well, the newborn’s physiological needs can be met in a timely manner, there is no chance of crying. This is a very good phenomenon; 2. abnormal: if the newborn suffers from bacterial infection, causing sepsis and septic meningitis, etc.. In these cases, the newborn will not cry or fuss, but this situation is often accompanied by a poor mental state, a significant decrease in the amount of milk, and sometimes accompanied by fever and other symptoms, to be treated in a timely manner.
