Can You Breastfeed When You're Sick? Here's What Parents Should Know
IMPORTANT NOTICE: Mother's milk is best for your baby. Improper or unnecessary use of feeding bottles and teats can be harmful to a baby's health.

Getting sick when you have a baby can feel especially difficult.
Along with feeling tired or unwell yourself, you may suddenly find yourself wondering:
“Is it still safe to breastfeed?”
It is a very understandable concern.
For many common illnesses, breastfeeding can usually continue. In fact, being unwell does not automatically mean you need to stop breastfeeding.
There are, however, some illnesses and medicines that need individual medical advice. So if you are unsure about your symptoms, treatment or your baby's health, speak with a qualified healthcare professional.
Can Your Illness Pass Through Breast Milk?
With many common infections, such as colds or influenza, the illness is generally spread through respiratory droplets or close contact rather than through breast milk itself.
By the time you realise you are unwell, your baby may already have been exposed through normal day-to-day contact.
Breast milk also contains antibodies and other immune-supporting components.
For many common illnesses, healthcare guidance therefore supports continuing breastfeeding while taking sensible precautions to reduce the spread of infection.
There are exceptions, which is why a specific diagnosis should always be discussed with your healthcare professional if you are uncertain.
What If You Have a Cold, Cough or Fever?
Having a common cold, sore throat, cough or mild fever does not necessarily mean breastfeeding needs to stop.
If you feel well enough to breastfeed, you can usually continue while paying extra attention to hygiene.
Try to:
- wash your hands thoroughly before touching your baby or breastfeeding
- cover coughs and sneezes
- avoid coughing or sneezing directly near your baby
- clean frequently touched surfaces
- follow medical advice about masks or other precautions when you have a respiratory infection
- rest whenever you can
If your symptoms are severe, getting worse or you are worried about your baby being exposed to an infection, contact your healthcare professional.
Take Care of Yourself Too
Being ill while caring for a baby can be exhausting.
Your body is already recovering, breastfeeding takes energy, and babies rarely adjust their routine simply because Mum is feeling unwell.
Give yourself permission to rest.
Drink according to your thirst, eat regular meals when you can and accept help from the people around you.
A partner or family member might:
- prepare meals
- bring you water
- take care of household tasks
- change the baby
- help you settle comfortably before breastfeeding
Sometimes the most useful support is simply giving a mother the chance to rest between feeds.
What About Medicines?
This is one area where it is better not to guess.
Many medicines can be used while breastfeeding, but not every medicine is suitable for every mother or baby.
Before taking prescription medicines, over-the-counter treatments, herbal products or cold and flu remedies, tell your doctor or pharmacist that you are breastfeeding.
A few simple rules can help:
- avoid self-medicating when you are unsure
- tell your doctor, pharmacist or other healthcare professional that you are breastfeeding
- take medicines only as advised
- check before using combination cold and flu products
- mention if your baby was premature or has an existing health condition
Do not stop a prescribed medicine—or breastfeeding—without speaking to an appropriate healthcare professional first.
The right advice depends on the particular medicine, the dose, your health and your baby's circumstances.
What If You're Too Unwell to Breastfeed Directly?
Sometimes a mother may feel too unwell to breastfeed comfortably.
If that happens, ask for help rather than assuming breastfeeding has to end.
Depending on your condition, a healthcare or lactation professional may advise you about expressing breast milk while you recover.
If expressed breast milk is being stored or handled, follow appropriate hygiene and storage guidance.
The important thing is to get advice that fits your individual situation rather than trying to manage a serious illness on your own.
When Should You Contact a Healthcare Professional?
Seek medical advice if:
- your fever is high, persistent or getting worse
- you feel seriously unwell
- you are having difficulty breathing
- you are unable to drink enough fluids
- you have been diagnosed with a significant infection
- you have been prescribed a new medicine and are unsure about breastfeeding
- breastfeeding has become unusually painful
- you are too unwell to care for your baby safely
- your baby develops symptoms or seems unusually unwell
Certain infections and treatments require specific breastfeeding advice, so a general online article should never replace an individual medical assessment.
Don't Stop Breastfeeding Just Because You're Worried
When you are already feeling unwell, it is easy for worry to take over.
You may wonder whether breastfeeding is making your baby more likely to become sick or whether stopping would be safer.
For many common illnesses, stopping breastfeeding is not routinely necessary.
If you are uncertain, speak with your doctor, paediatrician or qualified lactation professional before making a sudden change.
Getting clear advice can save you a lot of unnecessary worry.
Recovery Doesn't Have to Be a Solo Job
Mothers are often expected to carry on even when they are exhausted or sick.
You do not have to.
Let someone else make lunch.
Let the laundry wait.
Ask your partner or family to take over what they can.
Your health matters too.
Looking after yourself is not separate from looking after your baby—it is part of it.
The Reassuring Part
For many common illnesses, breastfeeding can continue while Mum recovers.
Good hygiene, appropriate medical care and a little extra support at home can make those difficult days easier.
And when something does not feel right, ask.
You do not need to work out every illness, medicine or breastfeeding question by yourself.
A qualified healthcare or lactation professional can help you understand what is safest for you and your baby.
