Your midwife may recommend another method of cleaning the stump. She may give you a powder called Ster-Zac that you sprinkle on to the belly button to help dry it out. Alternatively, she may use a surgical alcohol wipe to clean the stump which again, will dry it out. In some cases, you may be advised just to leave the whole area alone until it has fallen off and healed on its own. If you're unsure, ask your midwife.
The most important thing is to keep the stump as dry as you can and expose it to the air frequently. It may be a good idea to avoid using plastic pants until the stump has completely healed as they can trap moist air around the belly button area.
Don't rub or irritate the area around the stump. You may find that your baby will be more comfortable if you roll down the waistband of his nappy to keep it away. If you want, you can buy special newborn nappies with a small panel cut out of the front.
If you notice a small swelling around the belly button area you should see your GP. This can be a sign of an umbilical hernia.
