For the majority of healthy newborns, the number of times they urinate in a 24-hour period is around 6-10. If the number of times a newborn urinates in a day falls within this range, it is normal. If the number of times a newborn urinates is significantly less or more than this range, it is important to look for specific causes. If the number of times a newborn urinates is significantly low, it is often due to fever or enteritis. If a newborn baby has enteritis, he or she will lose too much fluid and the number of urinations will decrease. The most common cause of increased urination is a urinary tract infection, and the newborn should be given a routine urine test to further confirm the diagnosis.
