If your baby has been diagnosed with or you suspect eye infection and discharge in newborns (conjunctivitis), here is what the evidence says.
The short answer
Eye discharge in newborns is common and can be caused by a blocked tear duct (most frequent), chemical irritation from eye prophylaxis, or infection. While most sticky eyes are harmless, any significant redness, swelling, or pus-like discharge in the first month should be evaluated promptly, as certain infections can damage the eye.
Key takeaways
- Eye discharge in newborns is common and can be caused by a blocked tear duct (most frequent), chemical irritation from eye prophylaxis, or infection. While most sticky eyes are harmless, any significant redness, swelling, or pus-like discharge in the first month should be evaluated promptly, as certain infections can damage the eye.
- Usually normal when: Mild, watery or slightly yellowish discharge from one or both eyes with clear whites
- Call your doctor if: Significant eye swelling, redness, and thick pus-like discharge in the first month of life, which could indicate a serious bacterial infection requiring urgent antibiotic treatment
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, CDC guidelines, eye discharge in newborns is common and can be caused by a blocked tear duct (most frequent), chemical irritation from eye prophylaxis, or infection. While most sticky eyes are harmless, any significant redness, swelling, or pus-like discharge in the first month should be evaluated promptly, as certain infections can damage the eye. At 0-1 month, eye discharge in the first few days can be from the erythromycin eye ointment given at birth (chemical conjunctivitis), which is mild and self-resolving. More concerning causes include bacterial infections (such as gonorrhea or chlamydia, transmitted during delivery), which can cause serious eye damage if untreated. Gonococcal conjunctivitis typically presents within 2-5 days with severe swelling and thick pus. Chlamydial conjunctivitis usually appears at 5-14 days. A blocked tear duct causes watery, sometimes slightly yellowish discharge without significant redness or swelling. Any newborn with significant eye discharge, redness, or swelling in the first month should be seen promptly. It is generally considered normal when mild, watery or slightly yellowish discharge from one or both eyes with clear whites. However, you should contact your pediatrician promptly if significant eye swelling, redness, and thick pus-like discharge in the first month of life, which could indicate a serious bacterial infection requiring urgent antibiotic treatment.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
Eye discharge in the first few days can be from the erythromycin eye ointment given at birth (chemical conjunctivitis), which is mild and self-resolving. More concerning causes include bacterial infections (such as gonorrhea or chlamydia, transmitted during delivery), which can cause serious eye damage if untreated. Gonococcal conjunctivitis typically presents within 2-5 days with severe swelling and thick pus. Chlamydial conjunctivitis usually appears at 5-14 days. A blocked tear duct causes watery, sometimes slightly yellowish discharge without significant redness or swelling. Any newborn with significant eye discharge, redness, or swelling in the first month should be seen promptly.
1-3 months
A blocked tear duct remains the most common cause of persistent eye discharge. The discharge is typically clear or slightly yellow, accumulates during sleep, and the eye itself is not significantly red. Gentle nasolacrimal massage and warm compresses can help. If the eye becomes red, swollen, or the discharge becomes thick and green, infection may have developed and needs evaluation.
3-6 months
Blocked tear duct discharge may continue. Continue conservative management with massage. If symptoms worsen or the area near the inner corner of the eye becomes red and swollen (dacryocystitis), see your pediatrician promptly.
6-12 months
Most blocked tear ducts resolve by 12 months. If persistent, a simple probing procedure by a pediatric ophthalmologist can open the duct. Acute eye infections at any age should be evaluated.
What to Tell Your Pediatrician
- Describe when you first noticed eye infection and discharge in newborns (conjunctivitis) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if persistent eye discharge that does not improve with massage and cleaning.
- Mention if eye discharge that becomes thicker, more yellow, or green.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Mild, watery or slightly yellowish discharge from one or both eyes with clear whites
- Crusting on eyelashes after sleep that is easily cleaned
- Mild discharge following erythromycin eye ointment at birth that resolves in 1-2 days
- Blocked tear duct symptoms that improve with gentle massage
- Persistent eye discharge that does not improve with massage and cleaning
- Eye discharge that becomes thicker, more yellow, or green
- One eye seems consistently more affected than the other
- Significant eye swelling, redness, and thick pus-like discharge in the first month of life, which could indicate a serious bacterial infection requiring urgent antibiotic treatment
- Swollen, red area near the inner corner of the eye (possible dacryocystitis) with fever
What You Can Do at Home
- Keep track of when you notice eye infection and discharge in newborns (conjunctivitis) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild, watery or slightly yellowish discharge from one or both eyes with clear whites — this is generally within the range of normal.
- At 0-1 month, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if significant eye swelling, redness, and thick pus-like discharge in the first month of life, which could indicate a serious bacterial infection requiring urgent antibiotic treatment.
Related Conditions
Excessive Tearing in Newborns (Watery Eyes)
Watery or teary eyes in newborns are most commonly caused by a blocked tear duct (nasolacrimal duct obstruction), which affects up to 20% of babies. The condition is usually harmless and resolves on its own in the first year. Gentle massage of the tear duct area can help, and true tears typically do not appear until 1-3 months of age.
Blocked Tear Duct in Newborns
A blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes persistent tearing and sometimes yellowish discharge from one or both eyes. The tear duct, which drains tears from the eye into the nose, is not fully open. Most blocked tear ducts resolve on their own by 12 months. Gentle tear duct massage can help.
Erythromycin Eye Ointment at Birth
Erythromycin eye ointment is applied to newborns' eyes after birth to prevent ophthalmia neonatorum, a potentially sight-threatening eye infection caused by gonorrhea or chlamydia bacteria that can be transmitted during vaginal delivery. It is required by law in most states. The ointment may temporarily blur your baby's vision and cause mild eye irritation.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
