If a newborn has a short sleep time, the symptoms are mainly considered to be caused by the following conditions: first, physiological phenomenon. Some newborns have a physiological type of temperament with short sleeping time. Newborns are also very active during the day and very energetic. Newborns simply have short sleeping time, and their mental state, their own milk eating situation, and their growth and development are relatively good, so no special treatment is needed. Secondly, short sleeping time is caused by pathological reasons. If the newborn has abdominal pain, also due to abdominal pain resulting in a short sleep time, you can give timely application of probiotics for conditioning, such as the application of Mamma’s. Finally, if the short sleep is caused by calcium deficiency, accompanied by more head sweating and pillow baldness and other accompanying symptoms, you can give timely supplementation of calcium gluconate oral solution.
