Umbilical cord stump care: what to do and what to watch for

Newborn · Care · Reviewed 20 June 2026 · All articles

In the days after birth, your newborn's belly button will have a small, slightly alien-looking stump attached to it. This is the dried remnant of the umbilical cord - the lifeline that connected your baby to the placenta throughout pregnancy, delivering oxygen and nutrients and carrying away waste. Once the cord was clamped and cut at birth, the remaining segment begins to dry and shrivel. Most stumps fall off within one to three weeks, but the period between birth and that moment requires a little care and a lot of attention.

Many first-time parents feel anxious about the stump. It can look alarming as it darkens and dries, and there is a natural worry about doing something wrong. The reassuring truth is that the evidence-based approach to cord care is remarkably simple: keep it clean, keep it dry, leave it alone. This article explains what that means in practice, what normal looks like at each stage, and when to seek medical help urgently.

What the stump looks like as it heals

Understanding the normal sequence of appearance is one of the most helpful things you can do in the first weeks. A stump that is changing in expected ways can look worrying to a first-time parent, but knowing what is normal reduces anxiety considerably.

At birth, the cord stump is soft, moist, and a pale yellow-green or grey colour. It feels slightly gelatinous. This is normal - the cord tissue contains a substance called Wharton's jelly, which has a characteristic watery consistency.

In the first few days, the stump begins to dry. It typically changes colour, moving through yellow, tan, and eventually brown as it desiccates. The base - the point where the stump attaches to the skin of the belly button - usually dries from the outside inward. The stump may begin to shrivel and pull away slightly from the surrounding skin.

By one to two weeks, the stump is typically dark brown to black, firm, and noticeably shrunken. It may look like a small piece of dried twig or dark raisin attached to the navel. Some parents find this stage the most alarming-looking because the blackness can seem dramatic. In the absence of any signs of infection (described in detail below), black colouration simply indicates advanced drying and is a sign that separation is approaching.

Separation usually happens between one and three weeks after birth, with a range of up to five or six weeks being within the normal window. The stump loosens progressively and eventually detaches. You may notice a small spot of blood at the base when it separates - this is normal and not cause for concern unless bleeding continues for more than a few minutes.

After separation, the navel area may look slightly moist or pink for a day or two as it finishes healing. This is normal. A small amount of dried blood or yellowish crust at the navel right after the stump falls is not unusual. The area should be dry and healed within a few days of separation.

Dry cord care: the WHO-recommended approach

Cord care practices have changed significantly in the past few decades. For much of the twentieth century, routine application of antiseptics to the cord stump was standard practice in hospitals and midwifery. Purple antiseptic dye (gentian violet) was common in many countries, and alcohol-soaked swabs were widely used. The logic was intuitive: the cord stump is an open wound site, antiseptics prevent infection, therefore antiseptics should be applied.

However, well-designed research - including a systematic review published in the Cochrane Database and multiple randomised controlled trials across different healthcare settings - found that antiseptic application did not reduce the risk of omphalitis (cord infection) compared with simply keeping the area clean and dry, and in many studies actually slowed the time to cord separation. Dry cord care was associated with faster separation in the majority of studies, and similar or lower infection rates.

On the basis of this evidence, the World Health Organization published updated guidelines recommending dry cord care for infants born in clean environments with good access to healthcare. The NHS in the UK, German paediatric guidelines, and most major paediatric bodies worldwide have adopted this recommendation. Dry cord care means:

In some settings with limited access to clean water and healthcare, the WHO recommends applying a small amount of chlorhexidine antiseptic to the cord stump in the first week of life. This recommendation is specifically for higher-risk settings and does not apply in contexts with reliable access to healthcare and clean water.

What not to do

Equally important as knowing what to do is knowing what to avoid. Several common practices either delay healing, increase infection risk, or pose direct harm.

Do not clean with alcohol wipes. As described above, alcohol application to the cord stump is now considered outdated practice. It delays separation and provides no infection-prevention benefit in clean healthcare settings. Despite this, alcohol wipes are sometimes still recommended by well-meaning relatives or older parenting resources. Follow current guidance from your midwife or paediatrician.

Do not pull or tug the stump. The urge to gently loosen a stump that looks almost ready to fall off can be strong, but pulling at it - even gently - can cause bleeding and create an open wound that is vulnerable to infection. The stump will separate on its own when it is ready, and the internal tissue at the base needs to dry and seal completely before separation. Forcing it early risks disrupting this process.

Do not cover with plasters or bandages. Covering the stump traps moisture, which is exactly the opposite of what you want. Moisture delays drying and creates a more hospitable environment for bacteria. If the stump gets wet, the correct response is to gently pat it dry, not to cover it.

Do not immerse in water for baths. While light contact with clean water during careful sponge bathing is generally fine, prolonged immersion - as in a full baby bath - introduces unnecessary moisture to the stump and should be avoided until after the cord has fallen off and the navel has healed. Sponge bathing (wiping the baby's body with a damp cloth rather than submerging) is the recommended approach in the cord-stump period.

Avoid cultural practices that apply substances to the cord. In some cultures, applying herbs, oils, ash, animal substances, or other traditional preparations to the cord stump is a longstanding practice believed to protect the baby or speed healing. While these traditions carry deep cultural meaning, many of them introduce infection risk. Research from sub-Saharan Africa and South Asia has documented a clear link between the application of non-sterile substances to cord stumps and omphalitis and neonatal tetanus. If you wish to maintain a cultural practice, discuss it with your midwife or paediatrician first.

Warning signs: when to act quickly

Although omphalitis - bacterial infection of the umbilical cord and surrounding tissue - is relatively uncommon in countries with good neonatal care, it is a serious condition that can progress rapidly if not treated. Knowing the warning signs and acting on them promptly can prevent a serious outcome.

The normal healing process produces some small amounts of dried blood or yellowish crust at the base of the stump as it separates, and the stump itself can have a faint smell as it dries. These are not warning signs. You are looking for signs that suggest active bacterial growth in the tissue.

Seek same-day or urgent medical attention if you notice any of the following:

Omphalitis, when it occurs, typically presents in the first two weeks of life. The skin changes can spread alarmingly quickly - from a small rim of redness to a broad area of infection in hours. This is why the guidance is to seek same-day review rather than waiting to see if it resolves. Omphalitis is treated with antibiotics, and when caught early the outcomes are excellent. Delayed treatment can allow the infection to spread to deeper tissues (necrotising fasciitis) or into the bloodstream (sepsis), which are far more serious.

Umbilical granuloma: a common post-separation finding

After the cord stump falls off, a small proportion of babies develop an umbilical granuloma. This is a small, soft, pink or red lump of tissue at the base of the navel - usually the size of a pea or smaller. Unlike omphalitis, which involves spreading redness and infection, an umbilical granuloma is not infected. It is simply a small overgrowth of healing tissue that has not fully resolved.

Umbilical granulomas are common - estimated to occur in around one in 500 newborns - and are not dangerous, but they do need treatment to resolve. Left untreated, they can remain moist and cause minor discharge. The standard treatment is application of silver nitrate by a doctor or nurse, which causes the granuloma to dry up and fall off. Some small granulomas also resolve with the application of table salt, but this should only be attempted under instruction from a healthcare provider.

If you notice a persistent moist or slightly discharging navel that has not fully healed after the cord fell off, particularly if there is a visible pink lump, mention it at your baby's next health check. It is an easy and routine thing to treat.

Frequently asked questions

How long does the umbilical cord stump take to fall off?

The stump usually dries, shrivels, and falls off on its own between one and three weeks after birth. Some stumps take up to four or five weeks. As long as it is drying normally and there are no signs of infection, there is no need to intervene or pull it.

Should I clean the umbilical cord stump with alcohol?

No. Alcohol cleaning of the cord stump is now considered outdated. WHO and current paediatric guidelines recommend dry cord care - simply keep the area clean and dry, expose it to air when possible, and fold the nappy below the stump. Studies have shown that dry cord care leads to faster separation than alcohol cleaning.

When should I call a doctor about the cord stump?

Call your midwife or doctor promptly if you notice redness spreading from the base of the stump onto the surrounding skin, swelling, warmth, a foul smell, pus or discharge that is not the normal small amount of dried blood, or if your baby has a fever. These can be signs of omphalitis, a bacterial infection that requires prompt treatment.

Can I give my newborn a bath before the cord falls off?

Yes, you can bathe a newborn before the cord stump falls off, but it is safer to use sponge baths rather than immersing the baby in water. Keep the stump as dry as possible. If it does get wet, pat it gently dry with a clean cloth. Some health authorities advise waiting until the cord falls off before full baths.
