If you have noticed a soft bulge at your baby’s belly button — one that seems to pop out more when they cry and flatten when they are calm — you may be looking at an umbilical hernia. It looks alarming to many parents, but in babies this is very common and almost always harmless. Here is what it actually is, what to do, and the rare warning signs that need a doctor.
Quick Answer
An umbilical hernia is a soft bulge at or near the navel that happens when a small gap in the tummy muscles (where the umbilical cord once passed) has not fully closed, so a bit of tissue pushes through under the skin. It is common, usually harmless and painless, and most close on their own by about age 1-2 (most by 3-5 years). Do not tie a coin, button, band, cloth or tape over it — these do not help and can harm. Seek urgent care if the bulge becomes hard, swollen and will not flatten, is very tender or painful, the skin turns red, blue or dark, or your baby has vomiting, a swollen tummy, fever or seems very unwell.
What Is an Umbilical Hernia?
Before birth, the umbilical cord passes through a small opening in your baby’s abdominal (tummy) muscles. After the cord is cut and the stump falls off, that little opening usually closes up on its own. Sometimes it stays slightly open, and a small amount of soft tissue — sometimes a loop of intestine — pushes through this gap. That is what creates the bulge you see at the belly button.
You will often notice the bulge is more obvious when your baby cries, coughs, laughs or strains during a poo, because these all increase pressure inside the tummy and push the tissue outward. When your baby is calm, sleeping or lying down, it usually goes flat or soft again, and you can often gently press it back in. The bulge can range from the size of a small pea to a few centimetres across.
It’s Common and Usually Closes on Its Own
Umbilical hernias are one of the most common findings in newborns and young babies, and the good news is that the large majority need no treatment at all. As your baby grows, the tummy muscles strengthen and the gap gradually closes by itself.
Most umbilical hernias shrink and disappear by around 1 to 2 years of age, and the great majority have closed by 3 to 5 years. They are usually painless and do not bother the baby in the slightest — your baby will feed, sleep, play and grow exactly as expected. The hernia does not cause colic or fussiness, even though it may bulge more during a crying spell (the crying causes the bulge, not the other way around).
What NOT to Do — No Coins, Bands or Binding
This is important. There is a long-standing tradition of strapping a coin, a button, a piece of supari, a band or a tight cloth over the belly button to “push the hernia back in.” Please do not do this.
These methods do not help the hernia close any faster — the gap closes on its own timeline regardless. Worse, taping, binding or pressing an object against the delicate navel skin can trap moisture, rub the skin raw, and cause irritation, rashes or even infection of the area. There is no belt, binder or pressure remedy that speeds up healing.
The correct approach is simple: leave it alone. Keep the area clean and dry, dress your baby normally, and let nature do its work.
When Surgery Is Considered
Surgery for an umbilical hernia is uncommon and is only considered in specific situations — and it is always a decision your doctor makes after examining your baby. It may be discussed if the hernia has not closed by around 4 to 5 years of age, if it is very large, or if it is causing problems. A small, soft, easily reducible hernia in a baby is simply monitored over time, not operated on. The vast majority of children never need any procedure at all.
RED FLAGS — Seek Urgent Care
Very rarely, a loop of intestine can get trapped in the gap and lose its blood supply — this is called strangulation, and it is a medical emergency. Go to a doctor or hospital straight away if you notice any of these:
- The bulge becomes hard and swollen and will not go back in or flatten, even when your baby is calm or lying down.
- The bulge is very tender or painful — your baby cries in pain when it is touched, or cries persistently and is hard to settle.
- The skin over the bulge turns red, blue, purple or dark or looks discoloured.
- Your baby has vomiting, a swollen or hard tummy, fever, or seems very unwell along with the bulge.
These signs are uncommon, but they need to be checked urgently. When in doubt, get it seen.
When to See a Doctor
You should mention the bulge to your paediatrician at a routine check-up so they can confirm it is an umbilical hernia and keep an eye on it as your baby grows. There is no rush for a routine, soft, painless hernia — it is simply something to note and monitor. Seek care urgently, however, for any of the red flags listed above.
Indian Context
In many Indian families, the moment a navel bulge appears, out comes the coin, the supari, the band or the surma-soaked cloth, tied tightly over the belly button. This practice is extremely common — and it is both useless and potentially harmful. It does nothing to close the hernia, and the constant pressure and trapped moisture on a baby’s soft skin can cause rashes, broken skin and infection.
Please trust the simpler, safer path: an umbilical hernia is a normal, common part of many babies’ early months, and it closes on its own as the muscles strengthen. No binding, no remedies, no worry — just keep the area clean, dress your baby as usual, and let it heal naturally. Mention it at your next check-up for peace of mind.
Frequently Asked Questions
Q: Is an umbilical hernia painful for my baby?
A: No, in almost all cases it is painless and does not bother your baby at all. The bulge may pop out more when they cry, but the crying causes the bulge — not the other way around. Pain or tenderness at the bulge is unusual and is a sign to see a doctor.
Q: Will tying a coin or band over it help it close faster?
A: No. Coins, buttons, supari, bands, tape and binders do not help the hernia close and can damage the skin or cause infection. The gap closes on its own as the tummy muscles strengthen. Leave the area alone.
Q: At what age will it go away?
A: Most umbilical hernias close on their own by about 1 to 2 years, and the great majority by 3 to 5 years. If it has not closed by around 4 to 5 years, your doctor may discuss other options.
Q: My baby has an “outie” belly button — is that the same thing?
A: Not always. A permanent “outie” can simply be the way the navel healed and is not a hernia. A true hernia is a soft bulge that pushes out more with crying or straining and flattens when calm. Your paediatrician can tell the difference at a check-up.
Q: Can I gently push the bulge back in?
A: A soft, easily reducible hernia often goes back in with gentle pressure, and that is reassuring. But you do not need to keep pushing it in — it will pop back out and that is fine. What matters is watching for the red flags: a bulge that is hard, tender or will not go back is an emergency.
