It is normal for newborns to urinate 8 to 10 times a day. As the number of days of life increases, the number of times a newborn urinates before the full moon will slightly increase and may reach about 10 to 12 times, which is related to the gradual increase in the amount of milk a newborn eats. It is normal for there to be differences between individuals. Newborns due to the body organs and systems are not yet fully developed, the functions are still relatively weak, the bladder capacity is relatively small, the number of times to urinate will be relatively more, just 7 days after birth within a day of urine 8 ~ 10 times normal, more than 7 days will be in the 10 ~ 12 times or so. The number of times a newborn baby urinates will gradually decrease after the newborn baby reaches the age of one month, which is related to the gradual development of the bladder. It is recommended that parents pay attention to the newborn’s urination, find abnormalities in time to consult the doctor or go to the hospital to find the specific causes of the symptomatic conditioning or treatment, to avoid delaying the condition.
