Baby's Blocked Tear Duct: Sticky Eye, Normal or Not?
A baby with a blocked tear duct has one eye (sometimes both) that waters all the time, even when she isn’t crying, and often wakes up crusty or glued shut. It’s common and usually harmless. The duct that drains tears into the nose isn’t fully open yet, so tears pool and spill over. The AAP describes the classic picture as a constant watery eye where “the eye is not red and the eyelid is not swollen.” Most blocked tear ducts clear on their own within the first year. Redness, a swollen lid, a bump by the nose or a fever change the picture, and those are covered below.
What a blocked tear duct looks like
Tears are made all day, wash across the eye, and drain through a tiny opening in the inner corner of the eyelid into a duct that empties into the nose. The American Association for Pediatric Ophthalmology and Strabismus (AAPOS) explains that the most common reason a baby’s duct is blocked is “a thin membrane at the end of the duct.” That membrane is “present in about half of newborns but usually opens on its own shortly after birth.” When it doesn’t open, the tears have nowhere to go.
What you’ll actually see:
- A wet eye at rest. Tears well up and run down the cheek while she’s calm, feeding or asleep. KidsHealth puts it simply: “more tearing than usual (even when the child isn’t crying).”
- Crust in the morning. Dried, yellowish crust on the lashes after sleep, sometimes enough to stick the lids together.
- One side more than the other. Often it’s just one eye.
- Timing. It usually shows up early. KidsHealth says symptoms typically start “between birth and 12 weeks of age,” and AAPOS says blocked ducts “usually show up in the first month of life.”
The crust isn’t dirt and it isn’t your fault. AAPOS explains that crusting happens “because normal bacteria on the eyelid are not being ‘washed away’ through the duct.”
It can also come and go. AAPOS notes symptoms “often get worse when a child has a cold, allergies, or nasal congestion,” and that wind and cold weather can increase tearing. So the first stuffy-nosed week, when the eye suddenly looks worse, usually isn’t a new problem. If her nose is the part keeping you up, the newborn congestion guide covers that side.
How common it is, and how long it lasts
Very common. The AAP’s symptom checker says blocked tear ducts are “present in 10% of newborns.” The NHS adds that babies sometimes have watering eyes “because their tear ducts have not fully developed,” and that it “usually gets better by the time they’re a few weeks old.”
For the ones that hang on longer, AAPOS says “most (about 90%) clear on their own during the first year of life.” KidsHealth agrees that blocked ducts usually clear up “by the time a child is 1 year old.” If the duct still hasn’t opened around her first birthday, or the eye keeps getting infected, the pediatrician may refer you to a pediatric ophthalmologist. A simple procedure called probing can open the duct.
What helps at home
Wipe, don’t scrub. The AAP’s advice for crust or discharge is to remove it with warm water and wet cotton balls, and to wash your hands well afterwards. MedlinePlus suggests a warm, wet washcloth for crusts that build up. Gentle and often beats thorough and rare.
Ask about the massage. AAPOS describes tear-duct massage as “firm pressure with a finger in a downward motion over the inner corner of the eye,” which can push out trapped mucus and may help open the membrane. KidsHealth says your doctor may show you how to do it “several times a day at home for a few months.” Ask at a checkup to be shown the exact spot and how firm to press. It’s much easier to copy a hand than a written description, and it’s quick to learn.
Don’t reach for drops on your own. AAPOS says antibiotic drops or ointment are “used only if there is significant discharge or crusting,” that they “do not open the duct,” and that long-term use is discouraged. That’s a prescription decision for your pediatrician.
When a sticky eye is NOT a blocked tear duct
This is the part worth knowing well. A blocked duct gives a wet, crusty eye that otherwise looks normal. These don’t fit that pattern:
Discharge in the first days of life. MedlinePlus (from the US National Library of Medicine) says that in newborn eye infections, babies “develop drainage from the eyes within 1 day to 2 weeks after birth,” with eyelids that “become puffy, red, and tender” and drainage that can be “watery, bloody, or thick pus-like.” Some of these infections are passed on during birth and can damage the eye, so a newborn with that picture needs to be seen promptly. Don’t wait to see whether it’s “just the duct.”
A red, swollen eyelid, or a red bump beside the nose. AAPOS describes an infected tear duct (dacryocystitis) as “a painful, red, swollen bump near the duct with yellow-green discharge, along with fever or fatigue,” and calls it “a medical emergency.”
A bluish bump at the inner corner. AAPOS describes a dacryocele, fluid trapped in the duct, as a “bluish bump near the inner corner of the eye.” It usually appears in the first months and can be linked with cysts inside the nose that affect breathing. It needs a doctor’s look.
Tearing plus light sensitivity, or a cloudy eye. This one is rare, and it matters. AAPOS lists the most common signs of congenital glaucoma as too much tearing, “eye pain with bright light,” and “a large or cloudy cornea.” A baby who squeezes her eyes shut and turns away from light, or whose eye looks hazy or bigger than the other, needs an eye doctor.
When to call the pediatrician
| What you’re seeing | What to do |
|---|---|
| Watery eye, morning crust, white of the eye looks normal | Mention it at the next visit; ask to be shown the massage |
| Yellow or green pus that keeps coming back | Call within 24 hours (the AAP says she may need drops) |
| Discharge, puffy red lids, in the first two weeks of life | Call promptly, same day |
| Eyelid very red or very swollen | Call now (AAP) |
| Painful red bump beside the nose, especially with fever | Seek care now; AAPOS calls this an emergency |
| Bluish bump at the inner corner | Call the pediatrician |
| Squinting away from light, hazy or enlarged eye | Call; ask about a pediatric ophthalmologist |
| Any fever of 100.4°F (38°C) or higher under 12 weeks | Urgent, any hour; the AAP says don’t give fever medicine before she’s seen |
| Still watering at around a year, or repeated infections | Ask about a referral to a pediatric eye doctor |
If something about her eye just looks wrong to you, call. If you’re also watching her sleep and noticing her eyes don’t quite close, that’s a different and usually harmless thing, explained in baby sleeping with eyes open.
FAQ: blocked tear duct in babies
Is a blocked tear duct painful for my baby?
Usually not. The typical blocked duct is a wet, crusty eye on an otherwise content baby. Pain, a red or swollen lid, or a tender bump beside the nose points to infection and needs a call.
How long does a blocked tear duct last?
Often only weeks. The NHS says watery eyes from undeveloped ducts usually improve within the first few weeks. AAPOS says about 90% clear on their own during the first year.
Can both eyes have a blocked tear duct?
Yes. It can affect one or both eyes. A dacryocele on both sides is the version AAPOS flags as more likely to be linked with nasal cysts and breathing trouble.
Is it pink eye or a blocked tear duct?
A blocked duct gives a watery eye with a normal white and a normal lid. Pink eye usually brings redness and pus through the day. The AAP says pus in the eye without other warning signs is a call within 24 hours.
