Breast Milk in Baby’s Eyes: Old Remedy or a Risky Habit?
Breast milk is not a proven treatment for a baby’s eye infection, and a red, sticky newborn eye needs an urgent doctor visit. This guide explains why the home habit lasts, what the evidence says, and how to tell a routine watery eye from one that needs a doctor.
Advice here follows the usual age bands: under 6 months, 6 to 12 months, 1 to 3 years, 3 to 6 years, and over 6. The red-eye line changes at 30 days old, which sits inside the under 6 months band, so newborns get the strictest advice.
Quick facts
- Verdict: breast milk is not a proven eye treatment, and it may add bacteria to an eye that is already infected.
- Newborn red eye: under 30 days old with red, sticky eyes means an urgent appointment, according to NHS guidance.
- Watery sticky eye: can be a blocked tear duct. A Hull University Teaching Hospitals NHS Trust leaflet says nine in ten blocked tear ducts resolve on their own within the first year of life.
- Cleaning: cooled boiled water on a clean cotton wool pad, one piece for each eye.

Why do people put breast milk in a baby’s eye?
Breast milk is warm, gentle and always at hand, especially at three in the morning when a crusted eye looks alarming and the pharmacy is shut. The Breastfeeding Network notes that breast milk has traditionally been used to bathe eyes in some cultures. That is a tradition. It explains the habit without making it a medical instruction.
Grandmothers in many homes reached for a little breast milk when a baby’s eye looked sore. The care behind that instinct is real. The evidence for it as a treatment is not.
Is breast milk a treatment for a baby’s eye infection?
No, not as a proven treatment, and the evidence is mixed. Some research points to possible antimicrobial properties in breast milk, but that does not show it clears an eye infection in a baby. The Breastfeeding Network describes the evidence as mixed, not proven. Some findings point to a benefit, while others find that breast milk is not effective against some of the most common causes of conjunctivitis, and that it may make an infection worse by introducing other bacteria.
So the honest answer for a parent is simple. Breast milk may be familiar and gentle, but it has not been shown to clear an eye infection, and it may bring extra germs to a sore eye. Keep it for feeding.
Watery eye or red eye: how to tell the difference
A watery, sticky eye in a newborn can be a blocked tear duct rather than an infection. The table shows the usual split. When in doubt, treat the right-hand column as the one that needs a doctor.
| Usually routine watering | Needs a doctor |
|---|---|
| Watery eye with a clear, white surface | Red eye with pus or thick discharge |
| Sticky crust that wipes away in the morning | Swollen eyelids, or the eye stays shut |
| Tears running down the cheek, eye not red | Tender red lump at the inner corner of the eyelid |
| Eye settles with gentle cleaning | Red eye with a fever, or a fever of 38C or higher in a baby under 3 months |
The right-hand column needs a doctor’s answer, so do not wait for the eye to settle on its own. A baby under 30 days old with red, sticky eyes needs an urgent appointment, according to NHS guidance.
How do you clean crusty eyes at home?
- Wash your hands with soap and dry them.
- Boil clean water, then let it cool before it goes anywhere near your baby’s eye.
- Dip a clean cotton wool pad in the cooled water and squeeze out the extra.
- Gently wipe the eyelashes and lids to loosen the crust, using one pad for each eye.
- Throw each pad away after one use, and never dip a used pad back into the water.
What to skip
Nothing goes into a baby’s eye at home: no breast milk, no oil, no herbal water and no kohl. Keep the cleaning gentle and work on the outside of the lids and lashes only. Kohl and surma are covered separately in the surma and kajal guide.
A sticky eye with a clear white can be a blocked tear duct. The massage question, the day-to-day care and the longer course are covered in the watery sticky eye guide, so this article stays with the breast milk question and the urgent signs. For spread of infection between family members, see conjunctivitis at home. More in Eye Care.
When should a baby’s red eye see a doctor?
Use the age bands from the start of this article. Under 30 days old, red, sticky eyes need an urgent GP appointment, according to NHS guidance, and that is the point to call rather than wait. From 30 days onward, the NHS advice is to see a GP if symptoms have not cleared within 7 days, and the Breastfeeding Network advises getting help promptly if they get worse.
Get medical help as soon as possible for a baby with very red eyes or eye pain, and promptly if symptoms get worse, as the Breastfeeding Network advises. A red eye with pus, a swollen eyelid, an eye that stays shut, or a tender red lump at the inner corner of the eyelid needs a doctor’s check, so do not wait for it to settle. A fever of 38C or higher in a baby under 3 months: call NHS 111 now. Difficulty breathing, blue, grey or paler than usual lips, a baby who is drowsy and hard to wake, or one who is not interested in feeding means call 999 now, according to NHS advice. The doctor decides whether any drops are needed, so do not use drops from the shelf or the home medicine box on your own.
Bottom line: A red, sticky newborn eye is a doctor’s job, not a kitchen remedy. Breast milk belongs in the feeding routine. Keep the eye clean with cooled boiled water, learn the right-hand column of the table, and call the doctor when those signs appear. More baby care is in Bachon Ki Sehat.
Quick answers on breast milk and baby eyes
Is breast milk good for a baby’s eyes?
Breast milk is food for a baby. It is not a proven treatment for an eye infection, and the evidence for using it on the eye is mixed.
Can I put breast milk in my baby’s eye?
It is not a treatment to rely on, because the evidence is mixed and it may add bacteria to an eye that is already infected. Wipe the crust with cooled boiled water on a clean cotton pad, and see a doctor for red, swollen or pus-filled eyes.
Can breast milk make an eye infection worse?
It may, according to the Breastfeeding Network, by introducing other bacteria into an eye that already has an infection. That is one more reason to skip the habit once an eye looks red.
When should a newborn’s red eye see a doctor?
A baby under 30 days old with red, sticky eyes needs an urgent appointment, according to NHS guidance. Do not wait for it to settle on its own.
Is a watery eye in a newborn normal?
Watery eyes in a newborn can be a blocked tear duct, and a Hull University Teaching Hospitals NHS Trust leaflet says nine in ten blocked tear ducts resolve on their own within the first year of life.
Why is there crust on my baby’s eye in the morning?
Overnight crust can come with a blocked tear duct, and it can be wiped away with cooled boiled water on a clean cotton wool pad, one piece for each eye. If the eye is also very red, painful or getting worse, get medical help promptly.
Can I use eye drops from the chemist at home instead?
For a child under 2, NHS advice is that treatment needs a prescription from a GP. Do not use drops from the chemist at home without a doctor’s advice, because the doctor needs to check the eye first.
Is kohl or surma safe around a baby’s eyes?
No. Keep kohl and surma out of a baby’s eyes. The surma and kajal guide covers the products and the safer options.
Is a tender lump near a baby’s eye serious?
Do not wait it out. A tender red lump at the inner corner of the eyelid needs a doctor’s check promptly.
What if the watery eye is still there after the first birthday?
Take your baby back to the doctor for a check. In most cases a blocked tear duct clears by the first birthday, according to the Hull leaflet, so a watery eye that lasts longer deserves a professional look.
