If your baby has been diagnosed with or you suspect baby blocked tear duct (watery eye), here is what the evidence says.
The short answer
A blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes watery eyes and sometimes sticky discharge because tears cannot drain normally through the narrow duct into the nose. The good news is that about 90% of blocked tear ducts resolve on their own by age 12 months without any procedure.
Key takeaways
- A blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes watery eyes and sometimes sticky discharge because tears cannot drain normally through the narrow duct into the nose. The good news is that about 90% of blocked tear ducts resolve on their own by age 12 months without any procedure.
- Usually normal when: One or both eyes are frequently watery but the white of the eye is clear and not red
- Call your doctor if: The white part of your baby's eye becomes red and inflamed, the eyelid is swollen and red, or your baby seems to be in pain, as this may indicate conjunctivitis or dacryocystitis (infection of the tear duct sac) requiring 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.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP guidelines, a blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes watery eyes and sometimes sticky discharge because tears cannot drain normally through the narrow duct into the nose. The good news is that about 90% of blocked tear ducts resolve on their own by age 12 months without any procedure. At 0-3 months, blocked tear ducts often become apparent in the first few weeks of life as tear production increases. You may notice one or both eyes are persistently watery, with a sticky yellowish discharge that collects in the corner of the eye or crusts the eyelashes, especially after sleep. This is different from an eye infection (conjunctivitis) because the white of the eye is not red and your baby is not bothered by it. It is generally considered normal when one or both eyes are frequently watery but the white of the eye is clear and not red. However, you should contact your pediatrician promptly if the white part of your baby's eye becomes red and inflamed, the eyelid is swollen and red, or your baby seems to be in pain, as this may indicate conjunctivitis or dacryocystitis (infection of the tear duct sac) requiring antibiotic treatment.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Blocked tear ducts often become apparent in the first few weeks of life as tear production increases. You may notice one or both eyes are persistently watery, with a sticky yellowish discharge that collects in the corner of the eye or crusts the eyelashes, especially after sleep. This is different from an eye infection (conjunctivitis) because the white of the eye is not red and your baby is not bothered by it.
3-6 months
Gentle tear duct massage can help open the blocked duct. Your pediatrician can show you the technique: using a clean finger, apply gentle firm pressure at the inner corner of the eye near the nose and stroke downward. Do this 2-3 times a day. Clean any discharge by wiping with a warm, damp cloth from the inner corner outward. Many ducts open during this period.
6-12 months
Most blocked tear ducts open spontaneously by 12 months. If the blockage persists and causes frequent discharge or secondary infections, your pediatrician may refer you to a pediatric ophthalmologist to discuss probing. Probing is a brief outpatient procedure that is successful in about 80-90% of cases and is typically done around 9-12 months if the duct has not opened.
12 months+
If a blocked tear duct has not resolved by 12 months, probing is generally recommended. The success rate for probing is slightly lower after age 12-18 months. For persistent blockages, additional procedures such as balloon dilation or silicone tube placement may be considered. These are all very safe and effective treatments.
What to Tell Your Pediatrician
- Describe when you first noticed baby blocked tear duct (watery eye) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if the blocked tear duct has not resolved by 9-12 months and you would like to discuss whether probing is appropriate.
- Mention if your baby has frequent episodes of increased discharge that seem like recurrent mild infections on top of the blocked duct.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- One or both eyes are frequently watery but the white of the eye is clear and not red
- Your baby has a sticky yellowish discharge from the eye that you can wipe away, but the eye looks comfortable
- The tearing and discharge have been present since birth and are not getting worse
- Tear duct massage seems to temporarily relieve the discharge
- Your baby does not seem bothered by the watery eye and can open the eye normally
- The blocked tear duct has not resolved by 9-12 months and you would like to discuss whether probing is appropriate
- Your baby has frequent episodes of increased discharge that seem like recurrent mild infections on top of the blocked duct
- Both eyes are persistently affected and the discharge is significant
- The white part of your baby's eye becomes red and inflamed, the eyelid is swollen and red, or your baby seems to be in pain, as this may indicate conjunctivitis or dacryocystitis (infection of the tear duct sac) requiring antibiotic treatment
- You notice swelling, redness, or tenderness between the eye and the nose (at the inner corner), which could indicate an infected tear duct sac needing prompt treatment
What You Can Do at Home
- Keep track of when you notice baby blocked tear duct (watery eye) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that one or both eyes are frequently watery but the white of the eye is clear and not red — this is generally within the range of normal.
- At 0-3 months, 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 the white part of your baby's eye becomes red and inflamed, the eyelid is swollen and red, or your baby seems to be in pain, as this may indicate conjunctivitis or dacryocystitis (infection of the tear duct sac) requiring antibiotic treatment.

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.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Agenesis of the Corpus Callosum (ACC)
Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
