Umbilical Cord Care: The Current Guidance

The umbilical cord stump, the small dried remnant of the cord that connected your baby to the placenta, is a source of anxiety for many new parents. It looks fragile, it turns dark and shriveled, and it eventually falls off, leaving a small wound. The guidance on how to care for it has changed significantly over the years, and the current evidence-based advice is simpler and less interventionist than what many parents were taught.

The Old Advice vs the New

For decades, parents were told to clean the cord stump with alcohol at every diaper change, to keep it dry, and to fold the diaper down to keep it exposed to air. The goal was to prevent infection and speed drying. The current guidance, based on research from the World Health Organization and the American Academy of Pediatrics, is simpler: leave it alone. Dry cord care, which means keeping the stump clean and dry without applying anything, is now the standard in most developed countries.¹³

The change came from research showing that alcohol does not significantly speed drying and may actually kill the beneficial bacteria that help the stump separate. In settings with high infection rates, antiseptics may still be used, but in developed countries with clean water and good hygiene, dry cord care is equally effective and simpler.¹²

What to Do

Keep the stump clean and dry. If it gets dirty, which can happen with a diaper blowout, clean it gently with water and pat it dry. Do not submerge the baby in a bath until the stump has fallen off and the area has healed; sponge baths are fine. Dress the baby in loose clothing that does not press against the stump, and do not be afraid to put the diaper over it normally; folding the diaper down is not necessary.

What Not to Do

Do not pull or pick at the stump, even if it looks like it is hanging by a thread. It will fall off on its own, typically within one to two weeks. Do not apply alcohol, hydrogen peroxide, or any other substance unless specifically instructed by your pediatrician. Do not cover it with a bandage. The stump needs air to dry, and covering it traps moisture.

Signs of Infection

While cord infections are rare, they do occur, and it is important to know the signs. Contact your pediatrician if you notice redness spreading around the base of the cord, a foul-smelling discharge, yellowish pus, bleeding that does not stop, or if the baby develops a fever. A small amount of clear or slightly yellowish discharge is normal as the stump separates, but a foul smell, spreading redness, or fever are not.

When It Falls Off

The stump typically falls off between 7 and 14 days after birth. You may find it in the diaper or on the baby's clothes. There may be a small spot of blood or a raw-looking area where the stump was. This is normal. Keep the area clean and dry, and it will heal within a few days. If the area continues to ooze after a week, or if a small pink lump of tissue forms, contact your pediatrician; it may be a granuloma, which is easily treated.

The Bottom Line

Cord care is one area of newborn care where less is more. The current evidence says to leave it alone, keep it clean and dry, and let nature take its course. The stump will fall off when it is ready, the area will heal, and the belly button will form. The old rituals of alcohol swabs and diaper folding are not necessary, and the anxiety they caused was not either. Trust the process, watch for the signs of infection, and remember that the body knows what to do. Your job is to keep it clean and let it work.
