In the first few days after birth, due to low feeding volume, a newborn’s urine output can be very low, with only 4 to 5 times a day. After a few days, the frequency of urination increases rapidly, reaching 20 to 30 times a day before 6 months, with each urination about 30 milliliters. After 6 months, as semi-solid complementary foods are added and kidney function gradually improves, the frequency of urination decreases gradually. By the time the baby is one year old, the daily urination is about 15 to 16 times, with each urination about 60 milliliters (about one-third of a regular glass). By the age of 2 to 3 years, on average, there are about 10 times a day, and the amount of each urination gradually increases to about 90 milliliters. However, due to individual differences in babies and factors such as water intake and temperature, urine volume and frequency of urination can vary greatly.
