After your baby is born and the umbilical cord is clamped and cut, a small stump remains attached to your baby's belly button. This stump will dry out and fall off on its own—but in the meantime, it needs a little bit of care to heal properly.
The good news: modern umbilical cord care is simple. The old advice about swabbing with alcohol? We don't do that anymore. Here's what you actually need to know.
What to Expect
The cord stump typically falls off between 7 and 21 days after birth. During this time, it will go through several stages:
- Days 1–3: Yellowish-green and moist. The clamp may still be attached.
- Days 3–7: Starting to dry out and darken. Turning from yellow to brown or black.
- Days 7–14: Dry, shriveled, and getting smaller. May look like it's barely hanging on.
- Days 14–21: Falls off, leaving a small wound that heals within a few days.
The clamp is usually removed at your first pediatrician visit (around day 2–3). If it's still on after the hospital, that's fine too—it doesn't change the care.
How to Care for the Cord Stump
Keep It Clean and Dry
This is the entire strategy. Current AAP guidelines recommend "dry care"—keeping the stump clean and dry without applying any substances to it.
- Fold the diaper below the stump so it doesn't get wet or irritated. Many newborn diapers have a notch cut out for this purpose.
- Sponge baths only until the stump falls off. Full submersion baths should wait until the area has fully healed.
- If it gets dirty (diaper blowout, spit-up), gently clean around the base with a damp cotton swab or washcloth and let it air dry completely.
- Let air circulate. Don't cover it with tight clothing or bandages. Loose-fitting onesies are fine.
Don't
- Don't pull or twist the stump, even if it looks like it's ready to come off. Let it separate naturally.
- Don't apply alcohol, peroxide, or antibiotic ointment. Research shows that dry care leads to faster healing than alcohol application.
- Don't submerge baby in water until after it falls off and the area heals.
- Don't cover it with Band-Aids or tape.
When It Falls Off
When the stump separates, you may see a small amount of blood or pinkish fluid on the diaper or onesie. This is normal—like a scab coming off. There may also be a small raw area that looks moist for a day or two.
Continue keeping the area clean and dry. Within a few days, it should heal completely and look like a normal belly button.
It's also normal to see a small amount of clear or slightly yellow discharge as the area heals. This doesn't mean infection—it's part of the normal healing process.
Signs of Infection (When to Call)
Umbilical infections are uncommon, but they're serious when they do occur. Call your pediatrician if you see:
- Redness spreading outward from the base of the stump onto the surrounding skin
- Swelling around the belly button area
- Foul-smelling discharge (yellow or green pus)
- Baby has a fever (rectal temperature above 100.4°F)
- Baby seems to be in pain when you touch the area
- Bleeding that doesn't stop with gentle pressure
A little pinkness right at the base is normal. Redness that extends onto the belly skin is not.
Umbilical Granuloma
Sometimes after the stump falls off, a small, pinkish-red lump of moist tissue remains. This is called an umbilical granuloma. It's not dangerous, but it may ooze a small amount of clear or slightly yellow fluid.
Granulomas usually need treatment to resolve. In most cases, your pediatrician can treat it in the office with a small amount of silver nitrate—a quick, painless procedure that resolves the issue within a week or two.
Common Questions
What if it hasn't fallen off after 3 weeks? Most stumps fall off by 3 weeks, but some take longer—especially if the stump was thick. If it's still attached at 4 weeks with no signs of infection, mention it at your next visit but don't panic.
Can I put a belly band on it? Belly bands (compression wraps around the belly button) are used in some cultures. They don't cause harm, but they also don't help healing. If you use one, make sure the stump area can still air dry and check it regularly for any signs of irritation.
What if baby cries when I touch it? The cord stump itself has no nerve endings—baby shouldn't feel pain from gentle handling. If they seem genuinely distressed when you touch the area, check for redness or swelling and call your pediatrician.
Cord care is one of those things that feels intimidating but is actually very straightforward. Keep it dry, leave it alone, and let nature do the work.
