Newborn Umbilical Cord Care: What to Expect and When to Worry
TinyYears··3 min read
That tiny remnant of the umbilical cord is one of the things new parents worry about most — and one of the least complicated, once you know what to expect. Here's the complete guide.
What is the umbilical cord stump?
After birth, the umbilical cord is clamped and cut, leaving a short stump attached to your baby's navel. This stump dries out and falls off naturally, usually within 7–21 days. It changes colour as it dries — from yellowish-green at first, to brown, then black as it dries and shrivels. All of this is normal.
How to care for it
Current NHS guidance is simple: keep it clean and dry, and let it fall off on its own.
Do:
- Keep the nappy folded down below the stump to allow air to circulate (many newborn nappies have a notch for this)
- Pat dry gently after baths — don't rub
- Allow air to reach it whenever possible (during nappy-free time)
- Dress baby in loose clothing around the navel area
- Top-and-tail wash in the first weeks is fine — you don't need to submerge the cord
Don't:
- Apply antiseptic, cream, or surgical spirit — current UK guidance advises against these as they can delay healing
- Pull or pick at the stump — let it fall off on its own
- Cover with a plaster or bandage
- Submerge in a bath until it has fallen off completely (sponge bathing is preferred until then)
When the stump falls off
You may notice a tiny bit of blood or wetness when it separates — this is normal. The belly button underneath will take a few more days to fully heal.
Signs of infection to watch for
Infection is uncommon but does occur. Seek medical advice if you notice:
- Redness spreading around the base onto the surrounding skin
- Swelling or puffiness around the navel
- Warmth around the cord stump
- Yellow or green discharge (a small amount of slightly sticky fluid as it dries is normal; discharge with smell is not)
- Unpleasant odour coming from the cord
- Baby appearing unwell — fever, poor feeding, lethargy alongside any cord changes
If in doubt, contact your midwife or health visitor, or call 111.
What about a granuloma?
Occasionally, after the cord falls off, a small piece of moist pink tissue remains — this is called an umbilical granuloma. It's not infected, but it doesn't dry and heal properly on its own. Your GP or health visitor can treat it quickly with a silver nitrate application. It looks alarming but is a straightforward, common thing.
Belly buttons: innie or outie?
This is determined by genetics, not by how the cord was cut or clamped. You can't influence it — and "outies" (umbilical hernias or protruding belly buttons) often resolve on their own by the time a child is 4–5 years old.
The most important thing: resist the urge to interfere, keep it dry, and let nature do its job.
