It is mostly normal for two-month-old infants to sleep 6 or 7 hours at night, but environmental as well as disease factors cannot be ruled out. For two-month-old infants, an overall sleep duration of 10 hours or more and the ability to awaken naturally are normal signs. If a 2-month-old baby sleeps longer during the day, it may result in less sleep at night, with only 6 or 7 hours of sleep, which is also normal. It should be noted that if a two-month-old infant sleeps for a shorter period of time during the day and sleeps for only 6 or 7 hours at night, this is indicative of an abnormal presentation. It may be due to factors such as high ambient temperature, too bright light, noisy sound, etc. It is also not ruled out that it is due to factors such as indigestion, lack of calcium and other diseases. When a two-month-old baby sleeps for 6 or 7 hours at night, you should combine the baby’s performance with the baby’s performance, consult a doctor in time, cooperate with the doctor to conduct a detailed examination, and then do targeted treatment and therapy.
