Chalazion in babies: gentle care and when to ask

That bump on your baby’s eyelid is most likely a chalazion — a small, usually painless lump caused by a blocked oil gland. A chalazion in babies is common and usually settles with gentle care at home. Never squeeze the lump, and learn which signs mean it is time to ask a pediatric ophthalmologist.

What is a chalazion?

A chalazion is a small, usually painless lump inside the eyelid that forms when a meibomian oil gland becomes blocked.

Meibomian glands line the upper and lower eyelids and release oil that keeps tears from evaporating. When a gland’s opening blocks, oil backs up inside and the surrounding tissue becomes chronically inflamed. The result is a firm, rounded bump deep in the lid that grows gradually over weeks. A chalazion can appear on its own or after a stye has healed. For more on eyelid bumps generally, see our overview of eyelid bumps and our chalazion guide.

Chalazion vs stye in your baby

The two conditions both involve the oil glands of the eyelid. A stye (hordeolum) is a red, tender, infected bump that usually comes on overnight; a chalazion is a blocked, usually painless gland. They differ in cause, feel, and how fast they appear. Read our full stye guide:

One practical overlap: a stye that heals can leave behind a blocked gland, which then becomes a chalazion. A bump that starts painful, then stops hurting but lingers, has likely made exactly that transition.

Chalazion in babies: what the lump looks like

In an infant, a chalazion usually appears as a small, smooth, firm bump under the skin of the upper or lower eyelid. It is typically painless, so many babies do not seem bothered by it at all. You might notice it when washing your baby’s face, or see your baby blink or rub the eye a little more than usual. The skin over the lump usually looks normal, not red or inflamed. A chalazion generally does not affect vision unless it grows large enough to press on the eye, which is uncommon in babies.

Gentle warm compresses for a baby

Warm compresses are the mainstay of home care. The warmth softens the trapped oil so the blocked gland can drain, and the American Academy of Ophthalmology supports this as first-line care. Use this gentle routine:

1. Wash your hands thoroughly with soap and water before touching your baby’s face.
2. Soak a clean washcloth in warm — not hot — water. Test the temperature on the inside of your own wrist first; it should feel comfortably warm, never scalding.
3. Wring out the cloth so it is damp, not dripping, and hold it gently against your baby’s closed eyelid.
4. Keep it in place for a few minutes at a time, a few times each day, as long as your baby stays calm and comfortable.
5. Never leave a warm compress on a baby who is asleep or unattended, and never press or rub the lid.
6. Stop if your baby fusses, pulls away, or the skin looks irritated, and speak with your pediatrician.

A reheatable eye mask made for infants can also work, but only with an adult testing the heat and staying with the baby the whole time.

Cleaning your baby’s eyelid

Once the lid has softened, gently clean the eyelid margin with clean water and a soft washcloth or cotton pad once or twice a day. This keeps the gland openings clear. Use a separate cloth for each eye, wash your hands before and after, and avoid harsh soaps, adult lid scrubs, or anything fragranced unless your pediatrician advises it. There is no need to clean inside the eyelid — just the outside margin near the lashes.

Never squeeze or press the lump

Never squeeze, press, cut, or try to drain a chalazion at home. Squeezing can injure the delicate eyelid, spread infection, or make the inflammation worse. Let the warm compresses do the work, and leave any need for drainage to an eye specialist. The same rule applies if the lump seems to come to a head — let it be and seek professional advice instead.

How long to wait

Most infant chalazia settle over several weeks to a few months with gentle warm compresses and lid cleaning. A bump that stays the same size or slowly shrinks is usually not urgent, and there is no fixed timeline — every baby’s lump resolves at its own pace. If the lump keeps growing, becomes painful, or does not improve after a few weeks of compresses, book an eye exam so a specialist can take a look. A follow-up visit is also reasonable if you are simply unsure what the bump is. A quick exam can tell a chalazion from a stye or another eyelid bump, and give you a clear plan.

When to see a doctor

Home care covers most infant chalazia, but get seen promptly for any of these:

• Vision changes, or a baby who seems to squint or avoid light
• Redness or swelling spreading beyond the lid to the cheek or around the eye
• Fever along with the lump
• Pain out of proportion to the lump’s size, or pain that keeps worsening
• A lump that bleeds, ulcerates, or breaks through the skin
• A lump that keeps growing after a few weeks of compresses
• Bumps that keep returning in the same spot

A pediatric ophthalmologist can examine the eyelid and decide whether observation, a steroid injection, drainage, or simply more time is appropriate. You can find a children’s eye specialist through our local eye doctor guide.

FAQ

What is a chalazion in a baby?

A chalazion in a baby is a small, usually painless lump on the eyelid that forms when a meibomian oil gland becomes blocked and the oil backs up inside.

Is a chalazion in babies painful?

Usually not. A chalazion is typically painless, though a large lump can feel tender from pressure alone; clear pain points more toward a stye.

Can I use warm compresses on my baby?

Yes. Use a clean, warm — never hot — compress for short periods with an adult present, and never leave a baby with a compress while asleep.

Should I squeeze the lump?

No. Never squeeze, press, or try to drain a chalazion at home; that can injure the eyelid or spread infection.

How long does a baby chalazion last?

Most infant chalazia settle over several weeks to a few months with gentle care; one that keeps growing should be checked by an eye doctor.

When should I call a pediatric ophthalmologist?

Call if there are vision changes, spreading redness or swelling, fever, pain out of proportion, or a lump that keeps growing despite compresses.
