Umbilical Cord Stump: When It Falls Off, and When to Call
The umbilical cord stump usually falls off on its own within the first one to three weeks. The AAP says it “should dry and fall off by the time your baby is 3 weeks old,” and that a stump still attached after that needs a doctor’s visit. Until it falls off, the job is small: keep it clean and dry, fold the diaper below it, give sponge baths, and leave it alone. A few drops of blood on the diaper when it comes away are normal. Spreading redness, a foul-smelling yellow discharge, crying when you touch it, or a fever are not, and they’re a call to the pediatrician right away.
What normal drying looks like
The first look at the stump is a surprise. It’s a clamped, rubbery nub, and over the next days it changes in ways that look worse than they are. Cleveland Clinic describes the normal course: the stump “will get smaller and change in color from yellowish-green to brown to black. It will then fall off, leaving just the small mark of a belly button.”
So a shrivelled, dark, hard little twig is a stump doing its job. What matters is the skin around it. Cleveland Clinic says the surrounding skin “should be the same color as the rest of your baby’s skin (no redness or discoloration).”
I didn’t love looking at ours, and I mostly didn’t. That turned out to be the right instinct. Very little care is needed.
When does the umbilical cord fall off?
Usually within one to three weeks. The AAP’s bathing guide says it “usually happens by about one or two weeks of age,” and its cord-care page sets three weeks as the point where it should be gone. Cleveland Clinic gives the same three-week mark and says to call if the stump “hasn’t fallen off after three weeks,” even if it looks normal.
Don’t pull it, even when it’s hanging by a thread. Let it come away on its own, often inside a diaper or a onesie, where you’ll find it and feel strange about it.
How to care for the stump
The current advice is mostly about doing less.
- Keep it clean and dry. The AAP says “there is no need to use alcohol on the umbilical cord stump; just keep it clean.” The NHS says you only need to wash around it if it’s dirty with pee or poop, using “fresh cotton wool and warm water,” then “gently pat dry with a towel.”
- Fold the diaper below it. The AAP advises keeping the diaper folded down “to keep urine from soaking it.”
- Sponge baths only for now. The AAP says “only give your newborn sponge baths until the stump of the umbilical cord falls off.” Once the area has healed, you can try the tub. If you’re planning bath night around feeds, feed before or after the bath has the sequence.
Betteroo’s cord-care guide has a source-by-source table of the fall-off windows if you want them side by side. It also comes down against routine alcohol, matching the AAP.
Does an umbilical cord stump smell?
This is the question people actually type at 2am, so here’s the straight version. What the AAP and Cleveland Clinic flag is a foul smell that comes with a yellowish discharge. The AAP lists “foul-smelling yellowish discharge from the cord” as a sign of infection. Cleveland Clinic describes infected fluid that “may look yellowish in color and/or smell bad.”
You’ll read online that a faint smell from a drying stump is expected. I couldn’t confirm that on the medical sources I trust, so I won’t promise it. A practical way to think about it: a dry stump, normal-colored skin around it and a content baby is reassuring. Smell plus wetness, redness at the base, or a baby who cries when you touch the area is a call. If you can’t decide, call. Nobody minds that question about a two-week-old.
A little blood, and a damp belly button
A few drops of blood are normal. The AAP says “you may notice a few drops of blood on the diaper around the time the stump falls off; this is normal.” Active bleeding is different. If the cord area is actively bleeding, the AAP says to call your baby’s doctor immediately.
A moist pink lump after it falls off. Sometimes the belly button doesn’t dry completely and a small lump forms. The AAP calls this an umbilical granuloma, “a small reddened or brownish mass of scar tissue,” which “will drain a light-yellowish fluid.” It usually goes away in about a week. If it doesn’t, the pediatrician can treat it in the office.
A belly button that pushes out when she cries. That’s usually an umbilical hernia, a small gap in the belly wall. The AAP says it “is not a serious condition” and usually heals by itself “in the first 12 to 18 months.” Skip the old coin-and-tape trick. The AAP says it “will not help the hernia, and it may cause a skin rash.”
Signs of infection (omphalitis)
Cord infections are uncommon, but they move fast in newborns. Cleveland Clinic lists the signs:
- red or discolored skin around the stump
- skin that feels thick or hard around it
- fluid leaking from the stump, possibly yellowish or bad-smelling
- tenderness: “your baby may cry when you touch their umbilical stump or the skin around it”
It adds that a baby who is fussy, “overly sleepy or lethargic,” or feverish may have an infection that has spread. Cleveland Clinic says to call your pediatrician right away. Because these infections can progress quickly in newborns, your baby may be sent straight to the ER.
When to call the pediatrician
| What you’re seeing | What to do |
|---|---|
| Dark, dry, shrinking stump; normal skin around it | Normal. Keep it clean and dry |
| A few drops of blood on the diaper as it separates | Normal |
| Active bleeding from the cord area | Call immediately (AAP) |
| Redness spreading onto the belly, hard or swollen skin | Call right away |
| Yellow, foul-smelling discharge | Call right away |
| She cries when you touch the stump or the skin next to it | Call right away |
| Fever of 100.4°F (38°C) or higher | Urgent, any hour, with or without cord changes |
| Fussy, unusually sleepy or floppy with any cord change | Call now; you may be sent to the ER |
| Stump still attached at 3 weeks | Book a visit |
| Moist pink lump that hasn’t settled in about a week | Mention it; the pediatrician can treat it |
For everything else that’s happening in the first fortnight, see your 1-week-old baby and your 2-week-old baby, which is roughly when the stump comes off.

The AAP recommends sponge baths only until the stump has fallen off and the area has healed.
