Umbilical cord care for newborns is mostly about leaving it alone

For most babies, the best umbilical cord care is to keep the stump clean, dry and open to the air, and to put nothing on it. It usually dries and falls off within the first one to two weeks. Spreading redness, pus or a baby who seems unwell needs a doctor the same day.

How do I take care of my baby's umbilical cord stump?

Keep it clean, keep it dry, and leave it uncovered. WHO recommends clean, dry cord care for newborns.¹

In practice:

• Wash your hands before you touch the area.
• Fold the top of the nappy down, below the stump, so it stays out of urine and stool.
• Dress your baby in loose cotton clothes. Avoid tight belly bands.
• If the stump gets dirty, clean it with plain clean water and pat it dry with a soft cloth.
• Let it fall off on its own. Do not pull it, even when it hangs by a thread.

The stump has no nerves, so caring for it does not hurt your baby.

When does the umbilical cord fall off?

Most cords fall off in the first one to two weeks. In a study of babies given dry cord care, the cord came off after about 6 to 7 days on average.²

Over this time the stump dries, shrinks and turns from bluish white to brown or black. It becomes hard. The same study found that the cord took longer to come off when it got wet again and again.² That is one more reason to keep it dry.

What should I put on my baby's umbilical cord?

Nothing, in most cases. For babies born in hospital or in a clean home, plain dry care is the advice.¹

Families often ask Dr Dutta about surgical spirit, coconut oil, turmeric, powder or ash. Her answer surprises them: none of these is needed. The cord separates partly because white blood cells and normal skin bacteria do their work at its base. Your job is to keep it clean and let that process happen.

Should I use spirit or alcohol on the umbilical cord?

No, not routinely. A recent Cochrane review found no clear evidence that alcohol on the cord prevents infection.³

Spirit stings the skin around the cord and does not speed up separation in a useful way. If your doctor advises an antiseptic for a specific reason, follow that advice. Otherwise, plain water for cleaning and fresh air for drying is all the stump needs.

What is chlorhexidine for the cord, and does my baby need it?

Chlorhexidine is an antiseptic gel or solution. WHO advises it in the first week only where harmful traditional substances, such as animal dung, are commonly put on the cord.¹

In low and middle income countries, mostly with home births, chlorhexidine reduced cord infections.³ It also made the cord take almost 2 days longer to fall off.³ WHO notes that in babies whose cords were kept clean, chlorhexidine did not reduce deaths.¹ So for a baby born in a Kolkata hospital and cared for cleanly at home, dry care is enough. A health worker may use it after a rural home birth.

Why should I not put oil, ash, turmeric or powder on the cord?

These can carry germs into a wound that leads straight into the baby's bloodstream. After birth, the cord stump is an ideal place for bacteria to grow.⁴

Please avoid:

• Ash, cow dung, mud or soil. WHO names mud and animal dung as harmful on the cord, and ash or soil carry the same germs, including tetanus.¹
• Oil, ghee or butter. They keep the stump moist and hold dirt.
• Turmeric pastes, kajal or herbal mixes. They are not sterile.
• Powder. It cakes at the base and can hide early signs of infection.

Dr Dutta knows these customs come from love and a wish to protect. A clean, dry cord protects better.

How should I put a nappy on with the cord stump?

Fold the top edge of the nappy down so it sits below the stump. This keeps urine and stool off the cord and lets air reach it.

Some newborn nappies have a cut-out at the front for the cord. If yours do not, simply fold the waistband over before you fasten it. Use a loose cotton vest or jabla on top. In humid monsoon weather, change wet nappies promptly and let the area air for a few minutes during changes.

Can I bathe my baby before the umbilical cord falls off?

Yes. Many families choose sponge baths until the cord falls off, and that is a simple, safe approach. A short tub bath is also fine if you dry the area well afterwards.

The first bath should wait at least 24 hours after birth.¹ After any bath, pat the stump and the skin around it dry with a clean soft cloth. Do not rub it, and do not apply oil or powder afterwards.

Is it normal for the umbilical cord to bleed a little?

A few drops of blood are normal, especially when the cord comes off or catches on clothing. Press gently with clean gauze or a clean cloth for 2 to 3 minutes and it will stop.

Bleeding that soaks through the gauze, or does not stop with gentle pressure, is not normal. Please see a doctor the same day. Also tell the doctor if your baby did not receive vitamin K at birth, because the injection protects against a serious bleeding disorder of young babies.⁵

Is it normal for the cord stump to smell or ooze?

A mild smell and a little sticky, yellowish ooze at the base are common in the last days before the cord falls off. If the skin around it is not red and your baby is well, this is part of normal healing.

Keep cleaning with plain water and drying well. A smell that grows stronger, thick pus, or redness spreading onto the tummy is different. Those are signs of infection and need a doctor the same day.

What is the pink lump at my baby's belly button after the cord fell off?

A small, pink, moist lump that oozes a little is usually an umbilical granuloma. It is a common and harmless bit of extra healing tissue.

In a study of babies given dry cord care, about 9 percent developed a granuloma.² It does not always go away by itself, so show it to your paediatrician. Rarely, a lump that keeps leaking clear fluid, urine or stool is a different problem, a leftover connection to the bladder or gut, and needs a closer look. Please do not try to cut, tie or burn it at home.

Does salt treatment work for an umbilical granuloma?

Yes, often. In a randomised trial, a pinch of table salt applied by parents twice a day for 5 days cleared about 90 percent of granulomas.⁶ That was better than a single application of copper sulphate by a doctor.⁶

Salt draws water out of the moist tissue, and it shrinks. Do this only after a doctor has confirmed it is a granuloma and shown you how. Usually the salt is placed on the lump, covered with a small gauze for a short time, then cleaned off. Some doctors use silver nitrate instead.

Why does my baby's belly button stick out?

A soft bulge at the belly button that grows when your baby cries or strains is usually an umbilical hernia. It is a small gap in the tummy muscles, and it is common in young babies.

It does not hurt your baby. Most close by themselves. A systematic review found that waiting until 4 to 5 years of age, whatever the size, is safe and standard practice for hernias that cause no symptoms.⁷ Surgery is considered if it is still there after that.

Do coins or belly binders fix an umbilical hernia?

No. Coins taped onto the belly button, or tight bands to "push it in", do not help a hernia close. They can rub and break the skin, and a moist taped area can become infected.

The hernia closes as the tummy muscles grow stronger. Leave it alone and let your paediatrician check it at routine visits. See a doctor urgently if the bulge becomes hard, tender, red or cannot be pushed back, or if your baby vomits and is in pain.

What is omphalitis and how serious is it?

Omphalitis is an infection of the cord stump and the skin around it. It is uncommon with clean care, but it can spread fast into the tummy wall and blood, so it needs urgent treatment.

In one study of babies with dry care, about 4 percent had an infection of the cord area.² When cord infection spreads, it can cause cellulitis (deep skin infection), or rarely a severe tissue infection.⁴ Watch for:

• Redness that spreads outwards onto the tummy skin
• Swelling or hardness around the navel
• Thick pus, or a foul smell that gets stronger
• Your baby cries when the area is touched
• Fever, low temperature, poor feeding or unusual sleepiness

What if the cord has not fallen off after 3 weeks?

Show your baby to the paediatrician if the cord is still attached at about 3 weeks. Usually nothing serious is going on, and the cord simply needs more time.

Things that slow separation include the cord getting wet again and again, and chlorhexidine.^2,3 Very rarely, late separation is a clue to an immune problem, and your doctor will decide whether any tests are needed. Do not pull or cut the cord yourself.

When should I call the doctor about my baby's umbilical cord?

See a doctor the same day if you notice:

• Redness spreading from the base of the cord onto the tummy
• Swelling, pus, or a foul smell with redness
• Bleeding that soaks through gauze or does not stop with gentle pressure
• Clear or urine-like fluid leaking from the navel after the cord falls off
• A hard, painful or red bulge at the belly button
• Fever, cold skin, poor feeding, or a baby who seems unwell¹

For everything else: clean hands, a folded-down nappy, fresh air, and patience.
