Quick Answer
A newborn's umbilical cord stump typically falls off between 1 and 3 weeks after birth, though it can take up to 4 weeks in some cases. Until it falls off naturally, the stump needs to be kept clean and dry to prevent infection.
What to Expect
After birth, the umbilical cord is clamped and cut, leaving a small stump attached to your baby's belly button. Over the following days and weeks, the stump goes through a natural drying and healing process:
- Days 1–3: The stump is yellowish-green and moist
- Days 4–10: The stump begins to dry out, turning brown, then black and shriveled
- Weeks 1–3: The stump continues to shrink and dry until it falls off on its own
The average time is around 7 to 14 days, but anywhere up to 3 to 4 weeks is within the normal range. Do not try to pull or twist the stump off — let it detach naturally.
How to Care for the Umbilical Cord Stump
- Keep it dry: Fold the front of the nappy down below the stump to keep it exposed to air and prevent moisture buildup
- Stick to sponge baths: Avoid submerging your baby in water until the stump has fallen off and the belly button has fully healed
- Let air reach it: Dress your baby in loose clothing that does not rub against the stump
- Do not apply anything: Current guidance recommends keeping the stump clean and dry only — do not apply alcohol, antiseptic creams, or powders unless specifically advised by your pediatrician
- Do not pull it: Even if the stump looks ready to fall off, let it detach on its own
Signs of Normal Healing
- The stump gradually darkens from yellow-green to brown to black
- The stump shrinks and shrivels over time
- A small amount of dried blood or slight moisture at the base when it falls off is normal
- A small raw area at the belly button after the stump falls off — this heals within a few days
When It’s Worth Checking In With Your Pediatrician
Contact your pediatrician if you notice any of the following:
- Redness, swelling, or warmth spreading onto the skin around the base of the stump
- A foul smell coming from the stump area
- Yellow or green discharge (not just dried blood)
- Your baby cries or seems in pain when you touch the skin around the stump
- Fever alongside any of the above signs
- The stump has not fallen off after 4 weeks
- A pink, moist lump remains at the belly button after the stump falls off — this may be an umbilical granuloma, which is easily treated by your pediatrician
Key Takeaway
The umbilical cord stump falls off on its own within 1 to 3 weeks in most cases. The best thing you can do is keep it clean, dry, and undisturbed. Resist the urge to speed up the process — patience is the most effective approach, and the belly button will heal beautifully once the stump detaches naturally.
