Quick Answer
Umbilical cord care is one of the first practical skills new parents need to feel confident about. The core principle is straightforward: keep the stump dry and clean, expose it to air where possible, and avoid anything that might introduce moisture or bacteria to the site. The stump will dry, shrink, and fall off on its own, typically within 1 to 3 weeks. Most parents find the stump looks more alarming than it is, and with a simple, consistent approach, complications are uncommon.
How the Cord Stump Changes After Birth
At birth, the umbilical cord is cut and clamped, leaving a short stump attached to your baby's navel. In the first day or two, the stump is typically yellowish-green and slightly moist. Over the following days it begins to dry and shrink, changing colour progressively through yellow, then brown, and finally to black and hard as it desiccates completely. This colour progression is normal and does not indicate infection or a problem. The drier and harder the stump becomes, the closer it is to falling off.
The stump falls off on its own when the drying process is complete, leaving a small, healing navel wound underneath. The healing wound may take a further 7 to 10 days to fully close after the stump separates.
How to Care for the Cord Stump
Keep It Dry
Moisture is the primary enemy of healthy cord healing. A wet cord stump takes longer to dry and fall off, and prolonged moisture increases the risk of infection. Practical steps to keep the stump dry include:
- Fold the front of the nappy down below the stump at each nappy change, or use newborn nappies with a pre-cut notch designed for cord stumps, so that the stump is not covered by the nappy and is not exposed to moisture from urine
- Give sponge baths rather than full immersion baths until the stump has fallen off and the navel has fully healed
- If the stump gets wet during a nappy change or sponge bath, pat it gently dry with a clean, dry cotton pad or cloth
- Allow air circulation around the stump by keeping clothing loose around the navel area and, where practical, allowing the stump to be exposed to air for short periods
Do Not Pull or Twist the Stump
The stump will separate on its own when it is ready. Do not attempt to speed up the process by pulling, twisting, or cutting the stump. Even if it appears to be hanging by a thread, allow it to separate naturally. Forcing separation before the site is ready can cause bleeding and increases infection risk.
Cleaning the Stump
Current guidance from the World Health Organization and most pediatric bodies recommends dry cord care: keeping the stump clean and dry without applying any antiseptic, alcohol, or other product to the stump. Research has shown that dry cord care results in faster cord separation and lower rates of infection than routine antiseptic application in settings with access to clean water and standard hygiene practices.
If the stump becomes soiled (for example, from a nappy blowout), clean it gently with a damp cotton pad using plain water, then pat it completely dry. No special products are needed.
What Normal Looks Like
Parents sometimes worry unnecessarily about normal aspects of cord stump appearance. The following are normal and do not require any action:
- Yellow, brown, or black colouration as the stump dries
- A small amount of dried blood or brownish discharge around the base of the stump as it separates
- A slight smell as the stump dries (a strong or offensive odour is different and warrants assessment)
- The stump appearing to hang or dangle as it nears separation
- A small amount of blood at the navel immediately after the stump falls off, which typically stops within a few minutes with gentle pressure
Signs of Infection: When to Call Your Pediatrician
Umbilical cord infection (omphalitis) is uncommon but serious. Contact your pediatrician promptly if you notice any of the following:
- Redness, warmth, or swelling of the skin surrounding the base of the stump (not just the stump itself, but the skin around it)
- Yellow or green pus or discharge from the stump or the navel
- A strong or foul odour from the stump
- Your baby crying or showing signs of pain when the area around the stump is touched
- Fever in a newborn (a temperature of 38 degrees Celsius or 100.4 degrees Fahrenheit or above in a baby under 3 months always warrants immediate medical assessment)
A small amount of dried or brownish discharge at the base of the separating stump is normal, but any fresh, wet, coloured discharge from the surrounding skin should be assessed.
After the Stump Falls Off
Once the stump separates, the navel will look slightly raw and may have a small amount of dried blood or moisture at the centre. Continue keeping the area dry and clean for 7 to 10 days while it heals. Sponge baths can continue during this period if you prefer to be cautious; full immersion baths can begin once the navel site looks fully healed and dry.
Occasionally a small piece of red, moist tissue remains at the navel after the stump falls off. This is called an umbilical granuloma, a benign overgrowth of healing tissue. It does not resolve on its own and should be assessed by your pediatrician, who can treat it easily in the clinic.
Umbilical Hernia: What It Is and Whether to Worry
Some babies develop a soft bulge at the navel that becomes more prominent when the baby cries or strains. This is an umbilical hernia, caused by a small gap in the abdominal muscles through which a loop of intestine can push when intra-abdominal pressure increases. Umbilical hernias are common (occurring in around 10 to 30 percent of newborns, with higher rates in premature babies), are almost always harmless, and resolve on their own in the majority of cases by age 1 to 2 years. Do not attempt to tape, bind, or push the hernia back; these approaches do not help and can cause harm. Mention it to your pediatrician at the next well visit so it can be monitored. Surgical repair is occasionally needed for hernias that persist beyond age 4 or 5, but this is uncommon.
Key Takeaway
Keep the cord stump dry and clean, fold the nappy below the stump at every change, give sponge baths until the stump has fallen off and the navel has healed, and do not apply antiseptic, alcohol, or any other product to the stump. Allow the stump to separate naturally without pulling or twisting. The normal colour progression from yellowish-green to black is not a sign of a problem. Contact your pediatrician if you see redness or swelling of the surrounding skin, fresh coloured discharge, foul odour, or signs of pain, or if your baby has a fever. After the stump falls off, keep the area dry for a further 7 to 10 days and ask your pediatrician to assess any moist red tissue that remains.
