Excessive Tearing in Babies

The short answer

Excessive tearing (epiphora) in babies is most commonly caused by a blocked nasolacrimal duct (blocked tear duct), which affects about 6-20% of newborns. Tears cannot drain properly into the nose, causing them to overflow onto the cheek. This condition usually resolves on its own by 12 months of age. Other causes of excessive tearing include conjunctivitis, corneal abrasion, a foreign body, allergies, and rarely, infantile glaucoma. If excessive tearing is accompanied by light sensitivity or an enlarged eye, urgent evaluation is needed.

By Age

What to expect by age

Blocked tear ducts are very common in this age group. Newborns typically do not produce emotional tears until about 2-3 months, so a watery eye before this age is almost always due to a blocked duct. The tearing may be intermittent, and you may notice crusting or mild mucus accumulation. Treatment involves gentle lacrimal sac massage and keeping the eye clean.

Blocked tear ducts remain the most common cause of tearing. Perform gentle Crigler massage 2-3 times daily (firm pressure in a downward motion along the side of the nose near the inner eye corner) to help open the duct. Most blocked ducts resolve by 6 months. If the eye becomes very red, produces thick discharge, or the skin around the tear duct area becomes swollen, the duct may be infected.

If the blocked tear duct has not resolved, continued massage and observation are still appropriate through 12 months. Your pediatrician or ophthalmologist may discuss the option of tear duct probing, which is typically performed between 6-12 months if conservative measures fail. The procedure has a success rate of about 90%.

If excessive tearing persists beyond 12 months, referral to a pediatric ophthalmologist is recommended for probing or other interventions. In toddlers, new onset tearing may indicate allergies, an eye infection, a corneal scratch, or a foreign body. Rarely, persistent tearing with light sensitivity and an enlarged cornea could indicate congenital glaucoma.

What Should You Do?

When to take action

Probably normal when...
  • One or both eyes water intermittently, with mild clear or whitish discharge, starting in the first weeks of life
  • The eye itself looks white and healthy (no redness), and tearing improves with gentle massage
  • Crusting appears in the morning but is easily cleaned and does not bother the baby
  • Tearing gradually improves over the first year of life
Mention at your next visit when...
  • Tearing persists consistently beyond 6 months and is not improving with massage
  • Discharge becomes yellow or green, suggesting a possible secondary infection
  • The skin around the eye is becoming irritated from constant wetness
Act now when...
  • The inner corner of the eye near the nose becomes red, swollen, and tender, suggesting dacryocystitis (tear duct infection) that needs antibiotic treatment
  • Excessive tearing is accompanied by light sensitivity, a cloudy or enlarged cornea, or the eye appears larger than the other, which are signs of infantile glaucoma requiring emergency evaluation

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.

Air Quality and Baby Health

Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.

Altitude Sickness in Babies

Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.

Amblyopia (Lazy Eye) Treatment Timing

Amblyopia (lazy eye) is the most common cause of vision loss in children, affecting 2-3% of the population. It occurs when one eye develops weaker vision because the brain favors the other eye. Early detection and treatment are critical because the visual system is most responsive to treatment during early childhood. Treatment is most effective when started before age 7, though improvement is possible at older ages. Treatment options include patching the stronger eye, atropine eye drops, glasses, or a combination.
