Voiding, peeing or urinating most often occurs during the first several hours or day of life. However, after birth the amount of urine made for the first day or two is often normally decreased. Therefore, it is not abnormal for voiding to take 24-48 hours. If there is concern, x-rays such as a kidney ultrasound or a bladder voiding cystourethrogram (VCUG) can be done to further evaluate the urinary tract. Blood work such as electrolytes and BUN and Creatinine can also be done although these are sometimes hard to interpret as there is some carry-over from the mother's creatinine to the child.
