Eye care guide
Newborn eye discharge
Clinically reviewed · Last reviewed 2026-06-13
Why it happens
Tears normally drain through a tiny channel from the inner corner of the eye into the nose. In some babies this channel is not fully open at birth, so tears overflow and mucus builds up. This is called nasolacrimal duct obstruction and is very common.
Safe home care
Most cases improve with simple daily care while you wait for the duct to open naturally.
- Wash hands before touching the baby's face
- Soak crusts with cooled boiled water on clean cotton wool
- Wipe gently from the inner corner outward — use fresh cotton for each wipe
- Avoid sharing cloths or towels between eyes
When to seek help promptly
Contact your midwife, health visitor, GP or paediatrician the same day if you notice a red or swollen eyelid, the white of the eye looks red, the baby seems in pain, or discharge becomes thick and pus-like. These can suggest infection rather than a simple blocked duct.
If it persists
If sticky eyes continue beyond the first year, or frequent infections develop, an eye specialist may recommend gentle probing to open the duct or other treatment. Most babies never need this.
Frequently asked questions
Is newborn eye discharge always an infection?
No. Blocked tear ducts cause sticky eyes without redness of the white of the eye and are far more common than conjunctivitis in young babies.
Can I use breast milk to clean the eyes?
Cooled boiled water on clean cotton wool is safer and recommended. If you are unsure, ask your health visitor or doctor.
When do blocked tear ducts usually open?
Most open spontaneously within the first six to twelve months. Your clinician can advise if massage or referral is needed.
