The clamp and the remainder of baby’s umbilical cord falls off an average of 8/9 days after birth, but it can vary from one baby to another. The baby’s tummy button can leave an unpleasant smell and occasionally not all of the umbilical cord falls away. Wash your baby’s tummy button regularly with a mild soap. I am a great believer in the elements before rushing to medical intervention. Just washing and exposing the tummy button area to air will help.
A good tip is to fold the top of the nappy down so the germs do not harbour in a moist warm environment. If symptoms persist seek the advice of the doctor.
