A swollen eyelid in a baby or toddler can range from mild puffiness after sleep to significant swelling indicating infection. The most common causes are insect bites, allergies, and conjunctivitis. However, periorbital cellulitis (infection of the tissue around the eye) is a serious condition that requires urgent medical treatment to prevent spread to the eye socket.

Key takeaways

  • A swollen eyelid in a baby or toddler can range from mild puffiness after sleep to significant swelling indicating infection.
  • Most common cause: Insect bite or sting near the eye
  • Emergency: Eye swelling with eye bulging forward (proptosis) — possible orbital cellulitis
  • Home care: Apply cool compress to reduce swelling (clean cloth with cool water, 10 minutes several times daily)

Possible Causes

Insect bite or sting near the eyecommon
Allergic reaction (contact or environmental)common
Conjunctivitis (viral or bacterial)common
Chalazion or stye (meibomian gland blockage)uncommon
Preseptal (periorbital) cellulitisuncommon
Orbital cellulitis (deep tissue infection)rare
Blocked tear duct with secondary infection (dacryocystitis)uncommon
Nephrotic syndrome (bilateral eyelid swelling)rare

When to Seek Help

Emergency — Call 911 or go to ER:

  • Eye swelling with eye bulging forward (proptosis) — possible orbital cellulitis
  • Eyelid swelling with pain on eye movement or limited eye movement
  • Eyelid swelling with high fever and the child appearing very unwell
  • Rapid spread of redness from eyelid to cheek or forehead
  • Swelling after significant eye trauma

Urgent — See doctor today:

  • Red, warm, tender eyelid swelling with fever (possible periorbital cellulitis)
  • Eyelid swelling following recent sinus infection
  • Progressive eyelid swelling that is worsening over hours
  • Baby unable to open eye due to swelling with discharge

Same-day appointment:

  • Eyelid swelling that appears after an insect bite but is not improving after 24 hours
  • Stye or chalazion that is growing larger or becoming more painful
  • Mild eyelid swelling with conjunctivitis not responding to home care

Monitor at home:

  • Mild eyelid puffiness from insect bite with no redness spreading (usually resolves in 1-3 days)
  • Allergic eye swelling that responds to antihistamine
  • Small painless bump on eyelid (chalazion) that is stable
  • Morning puffiness that resolves within the day

By Age

0-3 months

Normal: Mild eyelid puffiness after sleep or crying is normal. Some newborns have puffy eyelids for the first few days of life.

Worry if: Red, warm, or progressive eyelid swelling especially with fever. In newborns, any significant eyelid swelling with discharge needs urgent evaluation (possible neonatal conjunctivitis or periorbital cellulitis).

3-12 months

Normal: Minor puffiness after naps or crying episodes is normal. Mild swelling with a cold (nasal congestion can cause puffiness around eyes).

Worry if: Swelling that is red, warm, tender, or spreading. Fever with eyelid swelling. Eye appearing to bulge forward. Baby unable to open the eye.

1-3 years

Normal: Insect bites near the eye commonly cause dramatic but harmless swelling. Allergic reactions can cause bilateral puffy eyelids.

Worry if: Progressive redness and swelling that is worsening over hours, pain with eye movement, fever, or swelling following a sinus infection. One-sided swelling that is warm and tender.

Any age

Normal: Brief puffiness in the morning that resolves within an hour is normal.

Worry if: Bilateral persistent eyelid swelling may indicate kidney problems (nephrotic syndrome) — look for swollen ankles or decreased urination as well.

Home Care

  • Apply cool compress to reduce swelling (clean cloth with cool water, 10 minutes several times daily)
  • For insect bites: oral antihistamine (diphenhydramine/cetirizine) if age-appropriate per doctor guidance
  • For styes: warm compress for 10-15 minutes 3-4 times daily to promote drainage
  • Do not squeeze or attempt to pop a stye or chalazion
  • Keep the area clean — gently clean eyelid margin with diluted baby shampoo on cotton ball
  • Monitor for signs of spreading redness or worsening — mark the border of redness with a pen to track
  • Elevate head slightly during sleep if swelling is significant
