Introduction
Waking up with a scratchy throat, body aches, and a fever is hard enough. When you are also a breastfeeding parent, that physical exhaustion often comes with a side of worry. You might find yourself checking your pump bottles or wondering if your baby seems satisfied after a feed. One of the most common questions we hear from parents dealing with a virus is whether the illness itself will dry up their milk.
At Milky Mama, we know that your milk supply is one of your top priorities. It is natural to feel anxious when your body is under stress. If you have noticed a dip in your output while feeling under the weather, you are not alone. Many parents experience a temporary change in their milk production when they are fighting off an infection like COVID-19, and our guide to low milk supply can help you sort through what is normal.
This article will explore why a decrease in supply can happen during illness and how you can protect your journey. We will cover the physiological reasons for a dip, how to maintain your supply while resting, and evidence-based ways to bring your volume back up once you feel better. Our goal is to provide you with the tools and reassurance you need to navigate this challenge.
While COVID-19 can cause a temporary decrease in breast milk supply due to dehydration, stress, and reduced feeding frequency, most parents can successfully restore their milk volume with proper support and management.
Why Milk Supply May Dip During Illness
When you are sick, your body shifts its energy toward healing. This shift is a survival mechanism. Your immune system is working overtime to fight off the virus. Sometimes, this means that secondary functions, like milk production, may take a temporary backseat. It is important to understand that the virus itself is rarely the direct cause of a low supply. Instead, it is usually the symptoms and the physical toll of the illness that lead to a decrease, and our guide to why breast milk supply is low can be a helpful next read.
The Role of Dehydration
Dehydration is perhaps the biggest culprit for a supply dip during COVID-19. Fevers cause you to lose fluids through sweat. If you have a cough or a sore throat, you might not feel like drinking as much as usual. Breast milk is about 88% water. If your body is low on fluids, it will prioritize keeping your vital organs hydrated over producing milk.
Even a mild case of dehydration can cause a noticeable difference in how full your breasts feel. You might notice that your pump sessions yield less than they did a few days ago. This is your body’s way of signaling that it needs more internal support.
Fever and Metabolic Demand
A fever increases your metabolic rate. This means your body is burning through calories and energy at a much faster pace to raise your temperature and kill off the virus. Lactation also requires a significant amount of energy—roughly 500 calories a day. When these two demands compete, your body may struggle to keep up with both.
Reduced Feeding Frequency
When you are exhausted, you might sleep through a session or find it difficult to hold your baby for long periods. If your baby is also sick, they might be sleepier and nurse less frequently. Milk production operates on a "supply and demand" basis. When milk is removed less often, your body receives signals to slow down production. This is often the primary reason supply drops during any major illness.
Key Takeaway: A dip in supply during illness is usually a result of physical stress, dehydration, and changes in nursing patterns rather than the virus itself.
The Impact of Stress on the Let-Down Reflex
Stress is a significant factor when you are sick. You are likely worried about your health, your baby’s health, and your ability to keep up with your daily responsibilities. This mental load can trigger the release of cortisol, often called the "stress hormone."
High levels of cortisol can interfere with the let-down reflex. The let-down reflex is the process where milk is released from the breast tissue into the milk ducts so it can be reached by the baby or the pump. This reflex is triggered by oxytocin, the "love hormone." When you are stressed or in pain, oxytocin can be suppressed.
You might still have milk in your breasts, but it may feel harder to get it to flow. This can lead to frustration during pumping or nursing, which only increases stress. Understanding that this is a hormonal response can help you take steps to relax and encourage your milk to flow.
Managing the Mental Load
It is okay to ask for help. If you have a partner, friend, or family member who can help with household chores or older children, now is the time to let them. Reducing your stress levels is not just good for your mental health; it is essential for your lactation recovery.
Safety and the Power of Antibodies
One of the biggest concerns parents have is whether they should continue to breastfeed while they have COVID-19. The current consensus from major health organizations is that breastfeeding is highly encouraged. Breasts were literally created to feed human babies, and they are also incredible at protecting them.
When you are exposed to a virus, your body begins creating antibodies to fight it. These antibodies are passed directly into your breast milk. This means that by the time you show symptoms, your baby has likely already been exposed, and your milk is providing them with the specific tools they need to stay healthy or have a milder case.
Protective Measures
If you are worried about passing the virus through respiratory droplets, you can take simple precautions:
- Wash your hands thoroughly before touching your baby or your pump.
- Wear a well-fitting mask while nursing or pumping.
- Clean any pump parts that come into contact with your milk or skin.
Continuing to nurse or pump not only protects your supply but also gives your baby the best possible immunological defense. Every drop counts, especially when there is a virus in the house.
Strategies for Maintaining Supply While Sick
You do not have to wait until you are 100% recovered to start supporting your milk supply. Small, manageable steps can make a big difference in preventing a major drop.
Focus on "Active" Rest
Rest is productive. When you are breastfeeding and sick, your only job is to rest and feed your baby. If possible, set up a "nursing station" in your bed or on the couch. Keep everything you need within arm's reach:
- Large bottles of water or electrolyte drinks.
- Nutritious, easy-to-grab snacks.
- Your phone or a book to keep you occupied.
- Extra burp cloths and diapers.
Prioritize Hydration
Drinking plain water is important, but when you have a fever, you also lose electrolytes. Our Pumpin’ Punch™ or Lactation LeMOOnade™ can be helpful here. They provide hydration support while also containing ingredients that many moms find helpful for supply. Try to take small sips throughout the day rather than drinking large amounts at once, especially if you are feeling nauseated.
Skin-to-Skin Contact
Even if you are too tired for a full nursing session, try to spend time skin-to-skin with your baby. Simply holding your baby against your bare chest can boost oxytocin levels. This helps with the let-down reflex and sends signals to your body to keep producing milk. It is also incredibly soothing for both you and your baby.
What to do next:
- Keep a 32-ounce water bottle nearby and aim to finish it several times a day.
- Set an alarm to remind yourself to nurse or pump every 2 to 3 hours if you are feeling very drowsy.
- Ask someone to bring you high-protein snacks to keep your energy up.
Using Your Pump to Protect Your Supply
If your baby is not nursing well or if you are too unwell to hold them for every feed, your breast pump becomes your best friend. The goal during the peak of illness is often maintenance rather than an increase.
If you notice your output is lower than usual, try not to panic. The numbers on the side of the bottle during a fever are not necessarily a reflection of your long-term potential. They are a reflection of your current hydration and energy levels. If you need a more structured approach, power pumping can help signal your body to increase production.
The Importance of Frequent Removal
Try to stick to your usual pumping schedule as much as possible. If you are too weak for a full 20-minute session, even a 10-minute session is better than skipping it entirely. Removing some milk frequently is more effective for maintaining supply than removing a lot of milk once or twice a day.
Gentle Massage
Before you start pumping, use gentle breast massage. This can help stimulate the nerves that trigger the let-down reflex. It can also help move milk through the ducts if you are feeling a bit of congestion or localized fullness.
Recovering Your Supply After Illness
Once the worst of the symptoms have passed, you might still see lower numbers than you are used to. This is common. Think of it as your body slowly "restarting" after a period of conservation. For many moms, supply returns to normal within a week or two of feeling better.
Power Pumping
If your supply needs an extra nudge, power pumping can be a helpful tool. This technique mimics a baby’s "cluster feeding" behavior. Cluster feeding is when a baby nurses very frequently over a short period to signal the body to make more milk.
To power pump:
- Pump for 20 minutes.
- Rest for 10 minutes.
- Pump for 10 minutes.
- Rest for 10 minutes.
- Pump for 10 minutes.
Doing this once a day for three to five days can often help signal your body to increase production. Remember, this is meant to be a temporary addition to your routine, not a permanent schedule.
Nutritional Support and Galactagogues
As you regain your appetite, focus on calorie-dense, nutrient-rich foods. Oats, flaxseed, and brewer’s yeast are traditional ingredients known as galactagogues. A galactagogue is simply a substance that may help support or increase milk supply.
We also offer herbal supplements like Lady Leche™ or Pump Hero™ that are designed to support lactation through different pathways.

The "Nursing Vacation"
If you can, take a "nursing vacation" for a day or two. This means staying in bed with your baby and nursing on demand. Let the dishes sit. Let the laundry wait. Frequent nursing is the most effective way to rebuild supply because the baby is much more efficient at removing milk than a pump.
Managing Medication While Breastfeeding
Many parents hesitate to take medicine for COVID-19 symptoms because they worry it will affect their milk. While some medications can cause a slight dip in supply, being in extreme pain or having a high fever can also lower your production.
Decongestants to Watch
Common over-the-counter decongestants containing pseudoephedrine are known to decrease milk supply. These are often found in "Cold and Flu" multi-symptom medications. If you have a stuffy nose, look for saline sprays or use a humidifier instead. If you must use a decongestant, consult with a lactation professional or your doctor first.
Safe Alternatives
Pain relievers like ibuprofen or acetaminophen are generally considered safe for breastfeeding and can help manage the aches and fevers that make nursing difficult. Always check with your healthcare provider or a pharmacist to ensure any medication you take is appropriate for your specific situation.
When to Seek Professional Support
Sometimes, despite your best efforts, supply stays low or you encounter other issues like mastitis or a poor latch. You don't have to navigate this alone.
Consult an IBCLC
An International Board Certified Lactation Consultant (IBCLC) is a clinical expert in breastfeeding. They can help you create a personalized plan to rebuild your supply. They can also check your baby’s transfer (how much milk they are actually getting) to ensure they are staying hydrated while you recover. If you need expert guidance, our Certified Lactation Consultant Breastfeeding Help page is a good place to start.
Watch the Diapers
The best way to tell if your baby is getting enough milk is to watch their output. If your baby has:
- 6 or more heavy wet diapers in 24 hours.
- Pale yellow urine (not dark or concentrated).
- Age-appropriate bowel movements.
- A generally alert and active demeanor when awake.
Then they are likely getting what they need, even if your pumping numbers look different than usual. If you see a decrease in wet diapers or your baby seems excessively lethargic, contact your pediatrician immediately.
The Mental Recovery: Be Kind to Yourself
Being a parent is a marathon. Being a breastfeeding parent while sick is a marathon run uphill in the rain. It is okay to feel frustrated. It is okay if you have to dip into your freezer stash or use formula while you recover. Using those tools does not mean your breastfeeding journey is over.
Your well-being matters just as much as your milk supply. If you are too focused on the ounces, you might miss the signs that your body needs more rest. Trust that your body knows how to heal and that with consistency and patience, your supply can bounce back.
Key Takeaway: Recovery is not always linear. Give your body grace as it navigates the path back to health and full milk production.

FAQ
Does the COVID-19 virus pass through breast milk?
Current research suggests that the virus is not transmitted through breast milk. Instead, breast milk provides the baby with essential antibodies that can help protect them from the virus or reduce the severity of symptoms. It is generally recommended to continue breastfeeding while following hygiene precautions like handwashing and wearing a mask.
How long does it take for milk supply to return after being sick?
Most parents see their milk supply begin to recover within a few days to two weeks after their symptoms improve. The timeline depends on how much the supply dipped and how frequently milk is being removed through nursing or pumping. Consistent stimulation and proper hydration are key to speeding up this process.
Can I take cold medicine while breastfeeding if I have COVID?
Some medications, particularly those containing pseudoephedrine, can significantly decrease milk supply. Pain relievers like ibuprofen and acetaminophen are usually considered safe, but it is always best to consult with your healthcare provider or a lactation consultant before taking any new medication. They can help you find options that manage your symptoms without negatively impacting your lactation.
Should I pump more often if I notice my supply is dropping?
If you have the energy, adding a few extra pumping sessions or a daily power pumping session can help signal your body to make more milk. However, if you are extremely fatigued, focus on maintaining your regular schedule first. Removing milk frequently, even for shorter durations, is more effective for supply maintenance than long, infrequent sessions.
