Newborn eye discharge - blocked tear duct, conjunctivitis, home care and red flags

You’ve just changed your newborn’s nappy, you go in for a cuddle, and then you see it: sticky yellow gunk stuck to their tiny eyelashes. Your heart drops. Is this an infection? Is it pink eye? Do you need to rush to A&E?

Take a breath. Baby eye discharge is very common in the first months of life, and most of the time it looks worse than it is. The trick is knowing what’s normal, what you can treat at home, and when to call the GP or 111.

This guide walks you through the main causes of pus in your baby’s eye, how to treat a blocked tear duct, what neonatal conjunctivitis looks like, and the red-flag signs that need urgent medical attention, especially in the UK context.

Why your newborn’s eyes get sticky

Newborn eye discharge can come from a few different issues. The three big ones are:

1. Blocked tear duct (dacryostenosis) - by far the most common.
2. Neonatal conjunctivitis - including pink eye in babies from irritation, bacteria, or viruses.
3. More serious eye infection - where the eyelids and eye itself look very angry and your baby seems unwell.

Before we dig in, one key point: if the white of the eye is not red and your baby seems comfortable, it is often a blocked tear duct, not a serious infection.

1. Blocked tear duct (dacryostenosis): the most common cause

What is a blocked tear duct in a baby?

A blocked tear duct (medical term dacryostenosis) happens when the tiny tube that normally drains tears from the eye into the nose is narrow or still a bit closed. This is incredibly common in newborns - up to 1 in 5 babies.

You might hear other parents say they had to “unblock baby’s tear duct” with massage. That is exactly what you’ll be learning to do.

Typical signs of a blocked tear duct

Pus in your baby’s eye from a blocked tear duct has a very specific pattern:

• It can affect one or both eyes.
• There is yellow, sticky discharge or crust, often worse:
  • After sleep or naps.
  • First thing in the morning.
• The white of the eye is not red.
• The eyelids are usually not swollen or angry-looking.
• Your baby seems happy and not in pain.
• When you press gently at the inner corner of the eye, more fluid or mucus may appear.

Parents often ask: “Is baby eye discharge normal?”
If the eye itself looks white and calm, and it matches the description above, then yes, this type of newborn eye discharge is usually a harmless blocked tear duct.

How long does it last?

In most cases, a blocked tear duct in a baby:

• Starts in the first few weeks of life.
• Gets better gradually as your baby grows.
• Resolves on its own by 6 to 12 months of age in the majority of babies.

Very occasionally, if it does not clear, an eye specialist may suggest a simple probing procedure to open the duct, usually after 1 year of age.

2. How to treat a blocked tear duct at home

You can safely treat baby eye discharge from a blocked tear duct at home, as long as the eye is not red and your baby seems otherwise well.

There are two key parts:

1. Lacrimal duct massage to help open the blockage.
2. Gentle cleaning to remove the pus in the baby’s eye.

Step-by-step: Lacrimal duct massage technique

This massage helps to gently push fluid through the blocked tear duct and can speed up recovery.

Do this 2 to 3 times a day.

1. Wash your hands thoroughly
   Use soap and water, dry with a clean towel. This is important, you don’t want to introduce new germs.

2. Find the right spot

   • Sit your baby slightly upright, either in your arms or on your lap.
   • Look at the inner corner of the eye, near the bridge of the nose.
   • That tiny area where the eyelids meet the nose is where the tear duct starts.

3. Place your finger correctly

   • Use a clean index finger.
   • Place it just next to the inner corner of the eye, toward the side of the nose, not on the eyeball.
   • You are pressing on the area of the tear sac, not the eye itself.

4. Apply gentle pressure and stroke downwards

   • Press gently but firmly. It should never hurt your baby. Think “firm cuddle pressure”, not poking.
   • Move your finger downwards along the side of the nose in a straight line.
   • Do this 5 to 10 times in one session.

5. Repeat regularly

   • Aim for 2 to 3 sessions a day.
   • It is often easiest:
     • After a bath.
     • During a nappy change.
     • While your baby is calm and fed.

If you are unsure about the pressure, your health visitor, midwife, or GP can demonstrate the massage.

Cleaning baby eye discharge safely

Even when the duct is blocked, you want to keep the eye area clean. That reduces the chance of a true baby eye infection developing on top.

Use this method for treating baby eye discharge at home:

1. Prepare your supplies

   • Cooled sterile saline from a pharmacy (or pre-boiled cooled tap water if saline is not available).
   • Cotton pads or cotton wool balls.
   • A clean towel.

2. Wash your hands
   Always before and after touching your baby’s eyes.

3. Wet one cotton pad with saline
   It should be damp, not dripping.

4. Wipe from inner to outer corner

   • Start at the inner corner near the nose.
   • Gently wipe outwards towards the ear.
   • Use one single stroke, do not rub back and forth.

5. Use a fresh pad for each wipe

   • If there is still discharge, use a new cotton pad.
   • Always use a separate pad for each eye so any infection does not spread from one eye to the other.

6. Pat dry

   • Gently pat the skin dry with a clean corner of a towel.

Repeat as needed during the day, especially after your baby wakes up.

3. Neonatal conjunctivitis: when “pink eye” is not just a blocked duct

Not all eye discharge comes from a blocked tear duct. Sometimes it is conjunctivitis, also known as pink eye.

Conjunctivitis means inflammation of the clear membrane that covers the white of the eye and inside of the eyelids. When it happens in newborns in the first month of life, it is called neonatal conjunctivitis.

This can be:

• Chemical - from irritation, often from antibiotic eye drops given after birth.
• Bacterial - from germs picked up in the birth canal or from the environment.
• Viral - usually linked to a viral infection.

Chemical conjunctivitis

In many UK hospitals, babies are no longer routinely given antibiotic eye drops at birth, but it still happens in some settings or specific situations.

Chemical irritation from drops can cause:

• Mild redness of the eye.
• Slight puffiness of the eyelids.
• Watery discharge.

This type of pink eye in babies usually:

• Appears in the first 24 hours after birth.
• Settles by 48 hours without specific treatment.
• Does not involve heavy pus or a very distressed baby.

Bacterial conjunctivitis in newborns

Bacterial conjunctivitis is the more worrying type of baby eye infection because it can sometimes be severe.

Signs might include:

• Red or pink eye - the white of the eye looks bloodshot.
• Swollen eyelids.
• Significant pus - thick yellow or green discharge that keeps coming back.
• The eye may stick shut, especially after sleep.
• Your baby may seem uncomfortable, fussy, or sensitive to light.

This can be caused by:

• Bacteria from the birth canal during delivery.
• Germs from hands or surfaces touching the baby’s eyes later.

Viral conjunctivitis

Viral pink eye in babies is less common in the first days of life, but can appear later, often alongside a cold.

You might see:

• Watery discharge that may become slightly sticky.
• Red, irritated-looking eyes.
• Sneezing, cough, or a runny nose as well.

Neonatal conjunctivitis treatment

Any redness of the eyeball plus discharge in a newborn needs proper assessment. Do not try to treat this yourself with leftover drops or home remedies.

For bacterial conjunctivitis, your GP or an eye specialist may:

• Examine your baby’s eyes carefully.
• Sometimes take a swab from the discharge.
• Prescribe antibiotic eye drops or ointment that are safe for newborns.

Viral conjunctivitis usually improves on its own. Your doctor may still want to check your baby to rule out anything serious, especially if they are very young.

While waiting to be seen:

• Keep cleaning the discharge as described earlier.
• Follow the hygiene rules below so the infection does not spread.

4. Infection signs that need urgent attention

Most sticky eyes are harmless. Some are not.

Contact your GP the same day or call NHS 111 urgently if you notice:

• Eyelid swelling and redness that looks worse than simple puffiness.
• Green, thick pus that keeps reappearing quickly after you clean it.
• Your baby cannot open the eye properly or cries when the eye is touched.
• The white of the eye looks red and irritated, not clear.
• Your baby seems unwell in themselves:
  • Fever (a temperature of 38°C or higher in a baby under 3 months is an emergency - call 999 or go to A&E).
  • Very sleepy or difficult to wake.
  • Poor feeding.

These signs can point to a more serious baby eye infection or spreading infection around the eye that needs urgent treatment, often with antibiotics.

Trust your gut. If you look at the eye and think “that looks really bad”, get help promptly.

5. Home care rules to keep your baby’s eyes safe

Whether you are dealing with a blocked tear duct or mild pink eye, good hygiene makes a big difference.

Follow these simple rules:

• Always wipe from inner to outer corner
  Start near the nose and move outwards, never towards the nose.

• Use a new cotton pad for each wipe
  Do not dip a dirty pad back into the saline.

• Use separate pads for each eye
  This reduces the risk of spreading infection from one eye to the other.

• Wash your hands before and after
  Use soap and water or an alcohol-based hand gel if you are out.

• Do not touch the eye with the dropper tip
  If your baby has been given eye drops or ointment:

  • Hold the bottle slightly above the eye.
  • Squeeze the drop so it falls into the lower lid pocket.
  • If the tip touches the lashes or skin, wipe it with a clean tissue and cap it straight away.

• Do not share cloths, towels, or flannels
  Use your baby’s own clean towel for their face.

6. When to call the doctor about pus in your baby’s eye

Here is a quick checklist to help you decide.

Call your GP, midwife, or health visitor soon (within a day or two) if:

• The white of the eye is red at all, not just the eyelids.
• The eyelids are swollen, especially if only one side is affected.
• The discharge doesn’t improve after 2 weeks of regular lacrimal duct massage and cleaning.
• Your baby seems in pain, cries when you touch near the eye, or avoids opening one eye.
• There is yellow or green pus in the baby’s eye that keeps coming back, even after good cleaning.

Seek urgent help (GP same day, NHS 111, or A&E if very unwell) if:

• Your baby has a fever or seems generally unwell.
• There is very thick green discharge, the eye is stuck shut repeatedly.
• The eyelids are very red, hot, and swollen, especially if the swelling is spreading.
• Your baby cannot open the eye or you cannot see the eyeball properly.
• You are simply worried something is not right. Parents often know.

Key takeaways for tired parents

When you notice pink eye in babies or sticky newborn eye discharge, run through this in your head:

• White eye, happy baby, yellow sticky discharge, more after sleep?
  Probably a blocked tear duct (dacryostenosis). Use:

  • Lacrimal duct massage.
  • Gentle cleaning with saline and cotton pads.
  • Patience - it usually clears by 6 to 12 months.

• Red eye, swollen lids, lots of pus?
  Could be conjunctivitis or a more serious baby eye infection. Your baby needs:

  • A proper check by a GP.
  • Possible antibiotic drops for bacterial infection.

• Very swollen, very red, fever, or baby looks unwell?
  Treat as urgent. Call NHS 111, your GP, or 999/A&E if seriously concerned.

You will feel like you spend half your day cleaning tiny eyes and tiny bottoms in those early weeks. That is completely normal. With the right technique and a clear idea of what to watch for, you can safely treat baby eye discharge at home and know when it is time to get extra help.
