Introduction
Waking up with a scratchy throat or a fever is stressful for any parent. When you are breastfeeding, that stress often doubles as you wonder how the illness might impact your baby and your milk supply. You might feel exhausted and worried that your body cannot keep up with the demands of nursing while fighting off a virus.
It is a common concern for many families navigating the challenges of the last few years. At Milky Mama, we hear from parents every day who are worried about their supply dipping during or after a bout with Covid-19, and our Certified Lactation Consultant Breastfeeding Help page can help. The good news is that your body is incredibly resilient, and there are many ways to support your lactation journey even when you are under the weather.
This article explores how illness impacts lactation and provides practical steps to maintain your supply. We will look at the connection between symptoms and milk production, how to stay hydrated, and what you can do to bounce back if you notice a decrease. Our goal is to provide the clinical expertise and emotional support you need to feel confident in your feeding choices.
While the virus itself does not typically cause a permanent end to milk production, the physical toll of being sick can create temporary challenges. By understanding the "why" behind these changes, you can take proactive steps to protect your milk supply.
Understanding the Relationship Between Illness and Lactation
When you get sick, your body shifts its energy toward fighting the infection. This is a natural and necessary response. However, because making milk also requires a significant amount of energy, you might notice some changes in your output.
Current research suggests that the Covid-19 virus is not typically found in breast milk. Instead, your milk actually becomes a source of protection for your baby. When you are exposed to a virus, your body begins producing antibodies to fight it. These antibodies pass into your milk, providing your baby with a personalized immune boost.
The concern regarding supply usually stems from the side effects of being sick rather than the virus itself. High fevers, dehydration, and extreme fatigue can all lead to a temporary dip in milk volume. For a deeper look, read our Does Dehydration Cause Low Milk Supply? guide. It is also common for your appetite to decrease when you feel unwell, which means you may not be taking in the calories your body needs for optimal production.
Why You Might See a Dip in Supply
If you notice your pump output is lower or your baby seems frustrated at the breast while you are sick, it is helpful to identify the cause. Understanding these factors can help you address them directly.
Dehydration and Electrolyte Loss
Fever and respiratory symptoms can lead to significant fluid loss. Breast milk is roughly 87% water. If your body is low on fluids, it will prioritize your vital organs over milk production. This is often the primary reason parents see a decrease in supply during any respiratory illness.
Reduced Frequency of Milk Removal
When you are feeling miserable, it is easy to miss a pumping session or for your baby to nap longer than usual. Milk production operates on a supply-and-demand basis. When milk is not removed frequently, your body receives a signal to slow down production. If you want more strategies for that, our Pumping for Breastfeeding: Your Essential Guide is a helpful read. Even a few skipped sessions over 24 to 48 hours can impact your daily total.
Physical and Emotional Stress
High levels of cortisol, the stress hormone, can interfere with the let-down reflex. The let-down reflex is what allows the milk to flow out of the breast. You might still have milk in the breast, but if you are stressed or in pain, your body may struggle to release it effectively. This can lead to a cycle of frustration for both you and your baby.
Medications and Their Effects
Some over-the-counter medications used to manage symptoms like congestion can impact supply. Decongestants, specifically those containing pseudoephedrine, are known to dry up secretions. While they help clear your nose, they can also significantly decrease milk volume for some people. Always check with a healthcare provider or a lactation professional before taking new medications while breastfeeding.
How to Protect Your Supply While Sick
The most important thing you can do when you have Covid-19 is to take care of yourself. Supporting your own recovery is the best way to support your milk supply.
Prioritize Hydration
Drinking water is essential, but when you have a fever, you also need to replenish electrolytes. Many parents find that lactation-specific drinks are helpful during this time. For example, our Pumpin' Punch™ can provide much-needed hydration along with ingredients that support lactation. Aim to keep a bottle of water or an electrolyte drink next to you at all times.
Keep the Milk Moving
Even if you are exhausted, try to keep your milk removal schedule as consistent as possible. If you are too tired to nurse, a short pumping session can help maintain your demand. You do not necessarily need to pump for 30 minutes; even 10 to 15 minutes of stimulation can signal to your body that the demand is still there.
Focus on Rest and Nutrition
Your body needs calories to fight a virus and to make milk. If you don't feel like eating a full meal, try small, nutrient-dense snacks. Foods like oats, flaxseed, and brewer's yeast are traditional galactagogues, which are substances that may help support milk supply. Many parents enjoy our Emergency Lactation Brownies or lactation cookies as a convenient way to get extra calories and lactation support when they don't have the energy to cook.
Key Takeaway: Supply dips during illness are usually temporary. Focus on hydration, frequent milk removal, and calorie intake to help your body maintain production while you recover.
Managing Symptoms Safely
Nursing while sick requires a balance of managing your symptoms and ensuring your baby stays healthy.
- Practice Good Hygiene: Wash your hands frequently, especially before nursing or handling pump parts. You may choose to wear a mask while in close contact with your baby to reduce the viral load they are exposed to.
- Monitor Your Baby: Keep an eye on your baby’s diaper output and overall demeanor. If they are having fewer wet diapers or seem unusually lethargic, contact their pediatrician.
- Antibody Protection: Remember that your milk is providing your baby with specific antibodies to the virus you are fighting. This is one of the most powerful ways your body protects your little one.
If you are concerned about specific symptoms or the safety of a medication, reaching out to a certified lactation consultant can provide peace of mind.
Rebuilding Your Supply After Illness
Once you start feeling better, you might find that your supply takes a few days to catch up. This is normal. Your body needs to rebuild its reserves before it can return to full production.
The Power of Skin-to-Skin
Spending time skin-to-skin with your baby can boost oxytocin levels. Oxytocin is the "love hormone" that triggers the let-down reflex and promotes bonding. It can also help regulate your baby's temperature and heart rate, making it a healing practice for both of you.
Power Pumping
If your supply has taken a significant hit, you might consider Increasing Your Milk Supply with Power Pumping for a few days. Power pumping mimics "cluster feeding," where a baby nurses frequently over a short period to signaled a growth spurt.
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 or twice a day for three to five days can help signal your body to increase production.
Herbal Support
Many parents find that herbal supplements can provide an extra boost during the recovery phase. Our supplements, such as Pumping Queen™, are designed to support milk volume and flow using carefully selected herbs.

Practice Patience
It can be discouraging to see less milk than usual, but try to remain patient with your body. It has just finished a major task by fighting off a virus. Most parents find that their supply returns to its previous levels within a week or two of feeling better, provided they continue to remove milk frequently.
Practical Steps for the Sick Breastfeeding Parent
When you are in the thick of it, it helps to have a simple plan. Here is a quick checklist to help you manage your supply while dealing with Covid-19:
- Drink 8-10 ounces of fluid every time you nurse or pump. Include electrolyte-rich drinks like our Lactation LeMOOnade™.
- Set an alarm on your phone to remind you to pump or nurse if you are napping frequently.
- Keep easy-to-grab snacks nearby. Our lactation treats are perfect for bedside nourishment.
- Lower your expectations for everything else. Focus only on resting and feeding your baby.
- Avoid decongestants if possible, as they may lead to a decrease in milk volume.
When to Seek Professional Help
Most of the time, a dip in supply during illness is a temporary hurdle. However, there are times when extra support is necessary.
You should consider reaching out to an International Board Certified Lactation Consultant (IBCLC) or your healthcare provider if:
- Your baby is showing signs of dehydration (fewer than 6 wet diapers in 24 hours for an older infant).
- Your supply does not begin to return after you have been recovered for a week.
- You are experiencing pain or signs of a clogged duct or mastitis.
- You feel overwhelmed and unsure how to continue your breastfeeding journey.
At Milky Mama, we believe that every drop counts. Whether you are exclusively breastfeeding, pumping, or combo-feeding, your well-being matters just as much as your baby’s nutrition. We are here to support you through the highs and lows of lactation. If you feel overwhelmed, our Breastfeeding 101 course can be a helpful next step.
Nutrition and Recovery
As you recover, focus on "nutrient density." This means choosing foods that pack a lot of vitamins and minerals into every bite. Your body is repairing tissues and replenishing the vitamins it used up during the infection.
Consider adding these to your recovery diet:
- Leafy greens: High in iron and calcium.
- Healthy fats: Avocado, nuts, and seeds provide the energy needed for milk production.
- Protein: Lean meats, eggs, or legumes help with tissue repair.
- Whole grains: Oats and brown rice provide sustained energy and support supply.
If you find it hard to eat enough, our Lady Leche™ or Pump Hero™ can be helpful additions to your routine. They are formulated to support the specific needs of lactating parents during times of stress or recovery.
The Role of Mental Health
Being sick while caring for an infant is physically and mentally exhausting. The anxiety about your milk supply can further increase your stress levels. It is important to acknowledge that you are doing something difficult.
If you find yourself feeling anxious or down, try to practice self-compassion. Your body is doing its best. If you need to dip into a freezer stash or use formula for a few days to get the rest you need, that is okay. Taking care of your mental health is a vital part of being a parent.
Key Takeaway: Your mental health directly impacts your physical health. Reducing stress and allowing yourself grace can actually help your milk supply recover faster.
Supporting the Immune System Long-Term
Once you have recovered from Covid-19, you might be looking for ways to support your immune system moving forward. A healthy immune system helps you stay strong for the daily demands of parenting.
- Probiotics: A healthy gut often leads to a healthier immune system. Many lactating parents find that probiotic-rich foods like yogurt or kefir are beneficial.
- Vitamin D: Many people are deficient in Vitamin D, which plays a major role in immune function. Talk to your doctor about an appropriate supplement.
- Consistent Sleep: While sleep is a luxury for new parents, even an extra 30-minute nap can help your body recover more effectively.
For ongoing support, Pump Hero™ is another option to explore.
Conclusion
Navigating Covid-19 while breastfeeding is undeniably challenging, but it does not have to mean the end of your breastfeeding journey.

FAQ
Can the Covid-19 virus pass through my breast milk to my baby?
Current clinical evidence suggests that the virus itself is not transmitted through breast milk. Instead, your breast milk contains antibodies that help protect your baby from the virus. It is generally recommended to continue breastfeeding while following good hygiene practices like handwashing and wearing a mask.
Why does my milk supply seem lower after having a fever?
A fever causes your body to lose fluids more quickly, which can lead to dehydration. Since breast milk is primarily water, dehydration can cause a temporary decrease in milk volume. Additionally, the energy your body spends fighting the fever is energy that isn't being used for milk production.
Are there any medications I should avoid for Covid-19 while breastfeeding?
Decongestants containing pseudoephedrine are known to potentially decrease milk supply by drying up secretions. It is important to consult with your healthcare provider or a lactation consultant before taking any new medications. They can help you find breastfeeding-friendly alternatives for managing your symptoms.
How long will it take for my milk supply to return to normal after being sick?
Most parents see their supply return to its previous levels within one to two weeks after their symptoms improve. To speed up this process, focus on hydration, increased frequency of milk removal, and adequate calorie intake. Staying consistent with nursing or pumping sessions is the most effective way to signal your body to increase production.
