Getting sick while breastfeeding raises an immediate and understandable concern: will nursing put your baby at risk? For most common illnesses, the answer from health authorities is clear and reassuring. Continuing to breastfeed while you are sick is not only safe in most cases, it can actually be beneficial for your baby. Here is what you need to know.
The General Guidance: Keep Breastfeeding
The Centers for Disease Control and Prevention states that you can and should continue breastfeeding while sick with most common illnesses, including colds, the flu, COVID-19, diarrhea, and even a breast infection such as mastitis. This guidance holds even when you are taking many over-the-counter medications to manage your symptoms, though it is always worth checking specific medications before taking them. The reason continuing to nurse is encouraged comes down to what breast milk does for your baby when you are unwell.
When your body is fighting an infection, it produces antibodies specific to that pathogen. Those antibodies pass into your breast milk almost immediately, which means your baby receives targeted immune protection against the exact illness you are fighting, often before they show any symptoms themselves. According to the CDC, breast milk contains antibodies and other immune factors that can help protect infants from illness, and this protective effect is present even when the nursing parent is actively sick.
Common Illnesses and What to Do
For colds and upper respiratory infections, continuing to breastfeed is safe and encouraged. The virus causing a cold or flu is transmitted through respiratory droplets, not through breast milk, so your baby is not being exposed to the illness through nursing. What does pass through the milk is the protective antibody response your body is generating. Practicing good hand hygiene before feeds and considering wearing a mask while nursing if you are coughing or sneezing reduces the risk of respiratory transmission during close contact with your baby.
For influenza specifically, the CDC recommends that breastfeeding continue during maternal flu illness. Women who receive the flu vaccine while pregnant or breastfeeding develop antibodies that are passed to their infants through breast milk, providing some protection for babies under 6 months who are not yet eligible for the vaccine themselves. If you are too unwell to nurse directly, pumping and having a healthy caregiver feed the expressed milk to your baby is a good alternative that keeps your supply protected while limiting respiratory exposure.
For gastrointestinal illnesses including stomach bugs and food poisoning, breastfeeding can continue safely. The pathogens responsible for most gastrointestinal illnesses are not transmitted through breast milk, and the protective antibodies in your milk again work in your baby's favor. Maintaining your hydration is especially important during a stomach illness while breastfeeding, as dehydration can temporarily reduce milk supply.
When to Pause or Seek Guidance
There are a small number of situations where breastfeeding may need to be paused or avoided, and these are the exceptions rather than the rule. Certain viral infections, specific medications, and some medical treatments require individual evaluation by a healthcare provider. If you are diagnosed with a condition that is new or serious, or if you are prescribed a medication and are unsure of its compatibility with breastfeeding, the LactMed database maintained by the National Library of Medicine is one of the most reliable resources available for checking specific substances. Your healthcare provider or a Storkpump IBCLC at askanIBCLC@storkpump.com can also help you navigate those decisions.
Medications While Breastfeeding
Many common over-the-counter cold and flu medications are compatible with breastfeeding, but some warrant closer attention. Acetaminophen is widely considered safe for breastfeeding moms for pain and fever management. Ibuprofen is also generally considered compatible. Decongestants containing pseudoephedrine deserve more caution, as research suggests they may reduce milk supply in some moms, particularly when taken regularly. According to LactMed, phenylephrine found in many nasal sprays may have less impact on supply than oral decongestants. Guaifenesin, the active ingredient in many expectorants, has limited study data in nursing moms but is generally considered low risk.
The most important step with any medication is to check before taking it and to tell your prescribing provider that you are breastfeeding. Resources like LactMed and your IBCLC are there to help you make informed decisions without unnecessary worry. Visit the Storkpump FAQ for more guidance on breastfeeding safety questions.
Protecting Your Milk Supply When You Are Sick
Being ill can temporarily affect your milk supply, particularly if you are dehydrated, not eating enough, or missing pumping sessions because you feel too unwell. Prioritizing fluids and maintaining your feeding or pumping schedule as closely as possible helps protect your supply during illness. If you are too sick to nurse directly, pumping at your regular intervals keeps your body producing at its usual level while your baby is fed expressed milk by a caregiver.
Having a reliable pump on hand before illness strikes is part of being prepared for situations like these. Browse insurance-covered breast pumps on Storkpump to find a covered option, and visit the Learning Center for more guidance on maintaining supply during challenging periods.
Frequently Asked Questions
Will my baby get sick if I breastfeed while I have a cold or flu?
Your baby is most likely to be exposed to respiratory illnesses through airborne droplets during close contact, not through your breast milk. Continuing to breastfeed while sick actually passes protective antibodies to your baby that may reduce the severity of illness if they do become infected. Practicing good hand hygiene and considering a mask during feeds if you are coughing or sneezing are practical precautions during respiratory illness.
Should I pump and dump if I am taking cold medication?
In most cases, no. Most common cold and flu medications are compatible with breastfeeding, and pumping and discarding milk is rarely necessary. Always check the specific medication using a trusted resource like LactMed or by consulting your healthcare provider or IBCLC. Pumping and dumping does not speed up the clearance of a medication from your body. Milk clears substances at the same rate as your bloodstream, so the only thing pumping and dumping accomplishes is protecting your supply if you need to skip a feed.
Can being sick cause my milk supply to drop?
Temporarily, yes. Dehydration, reduced food intake, and missed feeds during illness can cause a short-term dip in supply. The most effective way to protect your supply while sick is to stay hydrated, keep nursing or pumping as regularly as you can, and rest as much as possible. Supply typically recovers fully once you are feeling better and your routine returns to normal. If you experience a lasting supply change after illness, a Storkpump IBCLC can help you build it back.

What if I am too sick to breastfeed directly?
If nursing is not possible because you are too unwell or need to be temporarily separated from your baby, pumping at your regular feeding intervals is the best way to maintain your supply. Your expressed milk can be fed to your baby by a healthy caregiver. Having a quality double electric pump available for situations like this is one of the most practical preparations a breastfeeding mom can make. Browse Storkpump's covered pump options and check whether you qualify for a pump through insurance at little to no cost. If you have Medicaid, view Medicaid-covered pumps here.
