Newborn Umbilical Cord Stump Care: What to Do (and Not Do)

After birth, the umbilical cord is clamped and cut, leaving a small stump — about 2–3 centimeters of tissue — above your baby's belly button (the umbilicus). It no longer has any function; it's simply drying out. Over the first weeks it shrivels, darkens, and eventually detaches on its own. Your only job is to keep it clean and dry while that happens, and to leave it alone otherwise.

The AAP's guidance via HealthyChildren.org is straightforward. Here's the do/don't list:

Do:

• Keep the stump clean and dry. If secretions collect around the base, wipe them gently with a damp cotton swab, then pat dry carefully.
• Fold the diaper down below the cord so the stump stays outside the diaper and urine can't soak it. (Some disposables have a cut-out notch for this.)
• Let air circulate — no bandages, no wraps, no tight clothing over it.
• Check the skin around the base once a day at diaper changes.
• Wash your hands before and after handling the cord area.

Don't:

• Don't use alcohol or antiseptic on the stump routinely — dry cords fall off sooner.
• Don't pull, twist, or pick at the stump, even when it's hanging by a thread.
• Don't cover it with a bandage or tight diaper.
• Don't give tub baths until the stump has fallen off (sponge baths only — see below).
• Don't panic over a little crust or discoloration as it dries — color changes from yellowish to brown or gray are normal.

For the rest of the newborn routine, our newborn-care-checklist covers feeding, sleep, and diapering alongside cord care.

Usually within 1 to 3 weeks. Per the AAP's guidance, it should be gone by the time your baby is 3 weeks old — if it's still attached beyond that point, a doctor's visit is needed to check why.

It won't give you much warning. One day at a diaper change you'll find it in the diaper or the onesie, sometimes with a few drops of blood. That small amount of bleeding around the time the stump falls off is normal. If the cord is *actively* bleeding, call your baby's doctor immediately.

As it dries, the stump changes color — from a shiny yellowish hue to brown or gray. That's the drying process doing its job, not a sign of trouble.

Normal: dry, shriveled stump; gradual darkening; a few drops of blood when it detaches; a small amount of clear or slightly bloody oozing from the belly button for a few days after.

Not normal (see the warning-signs section below): yellow or green foul-smelling discharge, redness spreading outward from the base, swelling, or your baby crying in pain when the area is touched.

Stick to sponge baths only until the stump falls off — usually within the first week or two. Keeping the cord dry is the whole point of dry cord care, and a tub bath works against that.

How to sponge-bathe with a cord stump:

1. Lay your baby on a flat, comfortable surface (changing table, bed, or counter next to the sink) with supplies within reach.
2. Use a damp washcloth rinsed in plain, soap-free water; wash the face first, then the body, then the diaper area last.
3. Keep the cord stump out of the water — wash around it, not over it.
4. Pat everything dry, especially skin creases, and keep the baby warm by uncovering only the area you're washing.

Once the stump has fallen off and the navel looks dry and healed, tub baths are fine.

Umbilical cord infections (a condition called omphalitis) are uncommon but need prompt medical treatment. Contact your pediatrician if you notice any of these:

Also call if the cord actively bleeds, or if the stump is still attached after 3 weeks. When in doubt, call — pediatricians expect these calls from new parents.

You'll be left with your baby's belly button — and for a few days, possibly a small amount of clear or slightly bloody oozing as the navel finishes healing. Keep it clean and dry the same way, and it will settle on its own.

One common follow-up: the umbilical granuloma. Sometimes, instead of drying completely, the area forms a small reddened or brownish mass of scar tissue that stays on the belly button after the cord falls off, sometimes draining a light-yellowish fluid. Per the AAP's guidance, a granuloma usually goes away in about a week. If it doesn't, your pediatrician can treat it in the office — typically by drying or chemically cauterizing the tissue.

After that, the belly button is just a belly button. No special care needed.
