Yellow or Green Eye Discharge in Baby
The short answer
Yellow or green eye discharge in babies is very common, especially in newborns. The most frequent cause is a blocked tear duct (dacryostenosis), which affects up to 20% of newborns and usually resolves on its own by 12 months. Bacterial conjunctivitis (pink eye) is another common cause that produces thicker, more colored discharge. Simple blocked tear duct discharge tends to be milder and does not cause redness of the eye itself.
By Age
What to expect by age
Sticky, yellowish discharge in one or both eyes is extremely common in newborns. A blocked tear duct causes tears to pool and become slightly sticky or crusty but the white of the eye stays clear. Gentle tear duct massage (pressing softly at the inner corner of the eye and stroking downward) 2-3 times a day can help. Clean discharge with a warm, damp cloth. If the eye white turns pink or red, or discharge becomes thick and green, contact your pediatrician.
Blocked tear ducts often persist through the first year. As long as the eye is not red and your baby is not bothered by it, continued gentle massage and cleaning is usually sufficient. If the area beside the nose becomes red and swollen (dacryocystitis), this is an infection of the tear sac that needs antibiotic treatment. Most blocked ducts resolve by 12 months. If not, a simple outpatient procedure (tear duct probing) can open the duct.
New onset of yellow or green eye discharge in toddlers is more likely to be bacterial or viral conjunctivitis, often spread at daycare. Bacterial conjunctivitis produces thick yellow-green discharge that crusts the eye shut overnight. Viral conjunctivitis tends to be watery with some white or yellow discharge and often accompanies a cold. Both are highly contagious. Good handwashing is essential to prevent spread.
What Should You Do?
When to take action
- Mild, slightly yellowish crusting on eyelashes after sleep in a baby with a known blocked tear duct
- Small amounts of eye discharge during a cold
- One eye having more discharge than the other with a blocked duct
- The white of the eye remaining clear (not red) despite the discharge
- Eye discharge persists daily for more than a week
- Discharge is thick, green, or copious
- The eyelids are sticking together with discharge
- A blocked tear duct has not resolved by 12 months
- The white of the eye is significantly red along with thick discharge (bacterial conjunctivitis likely)
- The area beside the nose is red, swollen, and tender (dacryocystitis - tear sac infection)
- A newborn under 4 weeks develops eye discharge, which could indicate a serious infection acquired during birth
- Eye discharge is accompanied by eyelid swelling, fever, or pain

Baby Blocked Tear Duct (Watery Eye)
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.
Baby Pink Eye (Conjunctivitis)
Pink eye (conjunctivitis) is an inflammation of the clear membrane covering the white of the eye and the inner eyelids. In babies it can be caused by viruses, bacteria, allergens, or irritants. Bacterial pink eye causes thick yellow-green discharge and is treated with antibiotic eye drops. Viral pink eye causes watery discharge and resolves on its own. In newborns under 28 days, pink eye can be more serious and always requires medical evaluation.
Baby Eye Swollen, Puffy, or Red
A swollen or puffy eye in a baby can have many causes, from mild (insect bite, allergic reaction, or normal morning puffiness) to serious (periorbital or orbital cellulitis). The key distinctions are whether the swelling involves just the eyelid or the area around the eye, whether there is fever, whether the eye itself is red or has discharge, and whether the swelling came on suddenly or gradually. Eye swelling with fever always needs prompt medical evaluation.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
Baby or Toddler Body Odor - When Is It Normal?
Babies and toddlers can develop body odor from several benign causes: sour milk caught in skin folds, sweating, diaper area odor, strong-smelling foods in the diet, and certain medications or vitamins. True body odor (like adult BO from apocrine glands) should not occur before puberty. If your baby or young toddler has a persistent unusual body odor that is not explained by skin folds, diaper, or diet, it could indicate a metabolic condition, infection, or foreign body (especially in the nose or vaginal area). Unusual persistent odor warrants a doctor visit.
Baby Born with Teeth - Natal Teeth
Natal teeth (teeth present at birth) occur in about 1 in 2,000-3,000 births. In most cases, these are actual primary (baby) teeth that erupted early, not extra teeth. Most natal teeth are the lower front incisors. While natal teeth can sometimes cause breastfeeding difficulties or have a risk of becoming loose and being a choking hazard, many can be left in place and monitored. The decision to keep or remove a natal tooth depends on how firmly it is attached and whether it is causing problems.
