Newborn eyes: crossed eyes, sticky eye and when to worry

Last verified: July 19, 2026

The short answer: wandering or briefly crossed eyes are common and normal in the first 3 months, since eye muscle control is still developing. A sticky, yellow or white discharge is usually a blocked or narrow tear duct, not an infection, and it clears up with gentle cleaning over weeks to months. Get medical advice if a squint is there all the time, still happening past 3 months, or if the eye itself looks red or swollen rather than just sticky.

Crossed or wandering eyes: usually just development

A squint, where the eyes do not both point in the same direction at once, is common in young babies. A squint that comes and goes in a baby younger than 3 months old is usual and does not, by itself, need medical advice (NHS: Squint). Newborn eye muscles and the brain’s coordination between the two eyes are still developing, so brief wandering or crossing is part of that process settling in.

That said, get medical advice if:

• the squint is there all the time, at any age
• the squint comes and goes but your baby is older than 3 months
• you notice signs of a vision problem, such as your baby turning or tilting their head to look at things, or closing or covering one eye (NHS)

A squint that is not treated can, over time, affect how well that eye’s vision develops, sometimes leading to a lazy eye, so it is worth having it checked rather than waiting it out past the newborn window (NHS).

Why squints happen

Most childhood squints are linked to a problem with how the eye focuses, such as being short-sighted, long-sighted, or having astigmatism. Less commonly, a squint can be associated with other conditions, including infections like measles, genetic conditions such as Down’s syndrome, developmental delay, or problems affecting the brain and nerves, like cerebral palsy (NHS). None of this means a wandering newborn gaze is a red flag on its own, it is only worth knowing as context for why a doctor will ask a few extra questions at a check.

One rare but important reason doctors examine a new squint carefully: it can occasionally be a sign of retinoblastoma, a rare cancer of the eye that mostly affects young children. This is uncommon, but it is exactly why an unexplained or persistent squint gets a proper look rather than a “wait and see” at home (NHS).

Sticky eye: the other common newborn eye issue

Alongside squints, the other thing many parents notice in the early weeks is a sticky white or yellow discharge in the corner of one or both eyes, sometimes enough to stick the eyelashes together overnight. This is common in newborns while their tear ducts are still developing. A narrow or blocked tear duct is the usual cause, and it generally opens up and starts draining normally within the first year of life (NHS: My baby has a sticky eye).

Caring for a sticky eye at home:

• Clean with cooled, boiled water and cotton wool. Wipe each eye from the corner nearest the nose outward, using a fresh piece of cotton wool for every wipe and every eye (NHS).
• Wash your hands before and after, and avoid sharing towels, since discharge can carry infection between family members even when it is not conjunctivitis (NHS).
• A little massage can help. Using a clean finger, gentle pressure on the outside of the nose, near the corner of the eye, several times a day, can encourage a blocked tear duct to open (NHS).
• Eye drops are not needed just because discharge is yellow or green, unless the eye itself looks red (NHS).
• If the surrounding skin gets sore, a little plain petroleum jelly on clean, dry skin can protect it (NHS).

It usually clears up by itself within a few weeks or months. If the tear duct is still blocked and causing a sticky eye by 12 months old, your GP can refer your baby to an eye specialist. It is safe to wait a little longer if it is not bothering your baby, since it often keeps improving with time (NHS).

Sticky eye vs conjunctivitis: the difference that matters

Sticky eye and conjunctivitis are not the same thing, and telling them apart comes down to what the eye itself looks like, not the color of the discharge. Conjunctivitis affects the outer surface of the eye and inner eyelids, sometimes from a bacterial or viral infection picked up during or shortly after birth. Its signs are yellow or green discharge alongside redness and swelling of the eye (NHS).

In other words: discharge alone, with a normal-looking white of the eye, points to a simple blocked tear duct. Redness or swelling of the eye itself points to conjunctivitis, and that is the detail to contact your GP surgery about, since it may need antibiotic eye drops (NHS).

When to get help sooner rather than later

Alongside the squint and tear-duct guidance above, get medical help the same day if your baby has:

• redness or swelling of the eye, not just discharge
• discharge alongside a fever, poor feeding, or a baby who seems increasingly unwell or hard to settle
• an eye that is difficult to open because of swelling

And go straight to emergency care, or call for urgent help, if your baby is working hard to breathe, is unusually pale, blue, mottled, or very difficult to wake, alongside any eye symptoms (NHS).

And as always: your own concern is reason enough to ask.
