Umbilical cord care is simple: keep your newborn’s cord stump clean and dry, fold the diaper below it, give sponge baths, and let the stump fall off on its own, most often within 1 to 3 weeks.
That little stump can look alarming as it darkens and shrivels. Current U.S. advice asks you to do less, not more: the American Academy of Pediatrics (AAP) says there is no need to use alcohol on it; just keep it clean and dry.
This guide covers how to clean a newborn’s umbilical cord, what is normal, and the signs of infection, bleeding, a granuloma or a hernia that mean a call. Every number comes from the AAP, MedlinePlus, Mayo Clinic, Cleveland Clinic, the NIH’s StatPearls or ACOG.
Key Takeaways
Dry cord care is the U.S. approach: clean, dry, and no routine rubbing alcohol.
The stump falls off in 5 to 15 days (MedlinePlus) to 1 to 3 weeks (Mayo Clinic).
Fold the diaper below the stump, give sponge baths, and never pull it.
A few drops of blood at separation is normal. Active bleeding, pus, a foul smell, redness or fever is not.
Call if the stump is still attached at 3 weeks (AAP).

Quick Answer
Umbilical cord care means dry cord care: keep the stump clean and dry, fold the diaper below it, give sponge baths, skip routine rubbing alcohol, and never pull it off. It falls off in 5 to 15 days (MedlinePlus) to 1 to 3 weeks (Mayo Clinic, Cleveland Clinic). Call your pediatrician for pus, a foul smell, red skin around the stump, active bleeding or fever.
It is one less chore in the foggy first days of the fourth trimester.
What the Umbilical Cord and the Stump Are
During pregnancy, the umbilical cord brings nutrients and oxygen to your baby (Mayo Clinic). Cleveland Clinic describes a coiled, rope-like cord with one vein and two arteries, about 19.6 to 23.6 inches (50 to 60 centimeters) long. After birth it is clamped and cut, which leaves a short stump on your baby’s belly. Cutting the cord does not hurt your baby (Cleveland Clinic).
When Does the Umbilical Cord Stump Fall Off?
The major U.S. sources word the window a little differently:

AAP (HealthyChildren.org)
By the time your baby is 3 weeks old
Still attached beyond 3 weeks
MedlinePlus
By 5 to 15 days old
Not fallen off in 4 weeks
Mayo Clinic
Most often 1 to 3 weeks after birth
Not fallen off after 3 weeks
Cleveland Clinic
Typically 1 to 3 weeks after birth
Not fallen off after 3 weeks
When the umbilical cord stump falls off, by source.
The stages: as it dries, the stump shrinks and changes color from yellowish-green to brown to black before it falls off (Cleveland Clinic), usually well before the end of the newborn stage. If it is slow, call at 3 weeks and do not let it go past 4. MedlinePlus explains why late cases get checked: there may be a problem with the baby’s anatomy or immune system.
How to Clean a Newborn’s Umbilical Cord, Step by Step
Keep it clean and dry: that is the AAP’s whole instruction. Mayo Clinic adds: keep the stump exposed to air.
Clean it only when dirty: MedlinePlus says gauze and water only. For stool on the cord, Mayo Clinic suggests a washcloth with soap and water, then patting dry; Cleveland Clinic suggests a damp cloth, then air drying. Ask your pediatrician which they prefer.
Fold the diaper below the stump: this keeps urine from soaking it (AAP).
Give sponge baths: do not put your baby in a tub of water until the stump has fallen off (MedlinePlus).
Never pull it: even if it hangs by a thread. Pulled off too soon, it could start actively bleeding (MedlinePlus).
No rubbing alcohol. The AAP says there is no need for it, and Mayo Clinic says not to use it unless your healthcare professional tells you to. Cleveland Clinic says research shows alcohol could destroy healthy bacteria that help the stump fall off naturally.
Guidance differs by setting. StatPearls (NIH) says dry cord care is recommended in hospital settings where infection risk is low, while in developing countries with higher risk the antiseptic chlorhexidine has been shown to reduce cord infections.

Normal vs Call the Doctor: An Umbilical Cord Care Checklist
What you notice
Usually expected
Call your pediatrician
Color
Stump turning yellowish-green, then brown, then black (Cleveland Clinic)
Red skin around the base of the cord, or red streaks (AAP, Mayo Clinic)
Blood
A few drops on the diaper around the time the stump falls off (AAP); a tiny amount if the diaper rubs it (Mayo Clinic)
Active bleeding, bleeding that gets worse, or a few drops still showing after 3 days (AAP, Mayo Clinic)
Fluid or smell
A dry stump
Thick yellow fluid (pus), foul-smelling yellowish discharge, or a foul smell (Mayo Clinic, AAP)
Touch
Not tender
Swelling, tenderness, or crying when you touch the cord or the skin next to it (MedlinePlus, AAP)
Whole baby
Feeding and waking as usual
Fever of 100.4°F (38°C) or higher, poor feeding, lethargy, or floppy, poor muscle tone (MedlinePlus)
Umbilical cord stump: what is expected and when to call.
A note on smell. You may read that a mild odor is expected. We could not confirm that on the primary sources used here, which list a foul smell as a reason to call.
An infection of the stump and the tissue around it is called omphalitis. The AAP calls cord infections uncommon, and StatPearls puts the incidence in developed countries at 0.7%, with symptoms typically beginning at an average age of 3 days. An infected stump will need medical treatment (AAP).
The AAP’s signs are foul-smelling yellowish discharge, red skin around the base of the cord, and crying when you touch the cord or the skin next to it. MedlinePlus adds swelling and tenderness; Mayo Clinic adds red streaks and pus. On darker skin tones, redness can be hard to see, so Mayo Clinic advises feeling the skin: infected skin often feels warmer.
Signs of a more serious infection, per MedlinePlus: poor feeding, a fever of 100.4°F (38°C) or higher, lethargy, and floppy, poor muscle tone. Contact your baby’s provider immediately. Our newborn feeding schedule and sleepy newborn guide describe typical feeding and drowsiness, but do not wait on a baby who also has cord symptoms. StatPearls says treatment requires broad-spectrum antibiotics given by IV or injection.
Umbilical Granuloma, Umbilical Hernia and Bleeding
Umbilical granuloma. Sometimes, instead of drying completely, the cord forms a small reddened or brownish mass of scar tissue that stays on the belly button and drains a light-yellowish fluid (AAP). It will usually go away in about a week. If it does not, your pediatrician may need to dry it or chemically cauterize it.
Umbilical hernia. If the belly button pushes outward when your baby cries, it may be an umbilical hernia: a small hole in the muscular part of the abdominal wall (AAP). The AAP says it usually heals by itself in the first 12 to 18 months and may need surgery if not healed by 3 to 5 years; MedlinePlus says most get better without treatment by age 3 to 4. MedlinePlus says to call if your baby is very fussy or seems to have bad abdominal pain, or if the hernia becomes tender, swollen or discolored. Trapped tissue that loses its blood supply is rare but serious and needs surgery right away.
Bleeding. A few drops when the stump separates is normal (AAP). Active bleeding means that every time you wipe away a drop of blood, another drop appears (MedlinePlus). Call your baby’s doctor immediately.
After the Stump Falls Off: Belly Button Care and the First Tub Bath
When the stump drops off, the belly button might bleed a little; Cleveland Clinic calls light bleeding normal. Keep the area clean and dry and keep watching for the warning signs above. For the first real bath, Cleveland Clinic suggests waiting a couple of days. Our guide to the best baby bathtubs covers what to look for in a newborn tub.
Innie or Outie? What Does Not Shape the Belly Button
Family lore says the way the cord was clamped or cleaned decides between an innie and an outie. Nothing in the sources used here supports that. What they do describe are two things that can make a navel stick out for a while: a hernia and a granuloma. Taping a coin over it does not work. The AAP says tape or a coin will not help a hernia and may cause a skin rash.
Delayed Cord Clamping and Cord Blood Banking
Delayed cord clamping is waiting a short time before cutting the cord after birth. The American College of Obstetricians and Gynecologists (ACOG) recommends at least 30 to 60 seconds, which allows blood from the cord, with extra iron, stem cells and antibodies, to flow back into the baby. ACOG says it appears to be helpful for both full-term and preterm babies.
Cord blood banking stores cord blood, which contains stem cells used in some transplants. ACOG’s Committee Opinion 771 says public banking is the recommended method, routine storage with a private bank is not supported by the available evidence, and private banking may be considered when a family member has a medical condition that could benefit. Collection should not alter routine delayed clamping.
Active bleeding: each time you wipe a drop of blood away, another appears (AAP, MedlinePlus)
Bleeding that gets worse, or a few drops still showing after three days (Mayo Clinic)
Pus or foul-smelling yellowish discharge (AAP, Mayo Clinic)
Red skin around the base of the cord, red streaks, swelling or warmth (AAP, MedlinePlus, Mayo Clinic)
Crying when you touch the cord or the skin next to it (AAP)
A fever of 100.4°F (38°C) or higher, poor feeding, lethargy or a floppy body (MedlinePlus)
A belly button bulge that becomes tender, swollen or discolored (MedlinePlus)
Make an appointment if the stump is still attached at 3 weeks or a moist lump is still draining after about a week. If you cannot reach your pediatrician quickly and your newborn has a fever, is hard to wake, is not feeding, or keeps bleeding, go to an emergency department.
Frequently Asked Questions
How long does it take for the umbilical cord to fall off?
MedlinePlus says the stump should dry and fall off by 5 to 15 days of age; Mayo Clinic says 1 to 3 weeks after birth. The American Academy of Pediatrics says a doctor’s visit is needed if it is still attached beyond 3 weeks.
How do you do umbilical cord care at home?
Umbilical cord care at home means keeping the stump clean and dry. Fold the diaper below it, give sponge baths, and let it fall off on its own. Call your pediatrician for pus, a foul smell, redness, active bleeding or fever.
Should I clean my newborn’s umbilical cord with alcohol?
Usually not. The American Academy of Pediatrics says there is no need to use alcohol on the stump, and Mayo Clinic says not to swab it with rubbing alcohol unless your healthcare professional tells you to. Follow your own pediatrician’s instructions.
Is it normal for the umbilical cord to bleed when it falls off?
A little can be. The American Academy of Pediatrics says a few drops of blood on the diaper around that time is normal. Active bleeding, where another drop appears every time you wipe one away, means calling your baby’s doctor immediately.
What does an infected umbilical cord look like?
Signs include foul-smelling yellowish discharge, red skin around the base of the cord, swelling, tenderness, and crying when you touch the cord. On darker skin, Mayo Clinic suggests feeling for warmth. Fever, poor feeding or lethargy can mean a serious infection. Call right away.
Can I give my baby a bath before the umbilical cord falls off?
Stick with sponge baths. MedlinePlus says not to put your baby in a tub of water until the stump has fallen off. Cleveland Clinic suggests waiting a couple of days after the stump falls off before the first real bath.
