Your baby may take up to 48 hours to pass his/her first stool but most will have a meconium stool (black or greenish-black color) within 24 hours. Baby will pass urine for the first time with in 12 to 24 hours after birth. For the first 3 days baby may only urinate 2 to 3 times in 24 hours, but this will increase to 7 to 8 times in 24 hours by 1 week of life. Stool becomes looser in consistency and then slowly changes to yellow seedy stools after the first few days. Most babies usually pass stools several times a day. Both cloth and disposable diapers can be used in newborn babies. Diapers may need to be changed every 3-4 hours and barrier creams can be applied as a routine to prevent diaper rash.
