Posted on April 28, 2026
It is late at night, and you are staring at a breast pump bottle that is not as full as it used to be. Or perhaps your baby is pulling away from the breast, acting frustrated and fussy during a feeding. You might feel a heavy sense of worry or wonder if you have done something wrong. Please take a deep breath and know that you are not alone in this feeling.
Many parents experience shifts in their milk production at different stages of the breastfeeding journey. At Milky Mama, we understand how stressful it feels when you suspect your milk supply is decreasing, and our breastfeeding help page can help. This post will explore the common reasons why your supply might seem to be dropping and how you can support your body to bring it back up. We will cover physical health, lifestyle factors, and the biology of lactation to help you find a path forward.
Every drop counts, and your dedication to your baby is incredible. Understanding the "why" behind changes in your milk supply is the first step toward finding a solution that works for you.
Before looking at why supply might drop, it helps to understand how your body makes milk. Breastfeeding operates on a supply and demand system of milk production. When your baby removes milk from the breast, your body receives a signal to make more. If milk stays in the breast, your body receives a signal to slow down production.
This process is driven by hormones, specifically prolactin and oxytocin. Prolactin is the hormone responsible for making the milk. Oxytocin is responsible for the let-down reflex. The let-down reflex is the process where milk is released from the milk ducts and flows toward the nipple. When this cycle is interrupted, you may see a dip in your output.
Your milk contains a small protein called the Feedback Inhibitor of Lactation, or FIL. When the breast is full, the FIL tells the milk-making cells to stop working. When the breast is empty, the FIL is gone, and the cells can work at full speed. If you are not removing milk frequently or effectively, the FIL lingers and signals your body to dry up.
Key Takeaway: Frequent and effective milk removal is the most important factor in maintaining a healthy milk supply.
Sometimes, what feels like a supply drop is actually a normal part of breastfeeding. It is important to distinguish between "perceived" low supply and "actual" low supply. Many parents worry their milk is drying up when their body is simply becoming more efficient.
In the early weeks, your breasts may feel very full, hard, or even engorged. Around six to twelve weeks postpartum, your supply begins to regulate, as explained in our guide to when breast milk supply is established. This means your body has figured out exactly how much milk your baby needs. Your breasts may feel soft, and you might stop leaking. This does not mean your milk is drying up. It simply means your body is no longer over-producing.
You can never truly empty a breast. Milk is produced continuously, even while you are nursing. If your breasts feel "empty," they are actually at their highest rate of production. Babies often cluster feed—nursing very frequently for a few hours—to help signal your body to increase supply for a growth spurt. If you want more context, our cluster feeding and milk supply guide is a helpful next step.
If you are nursing and pumping, do not use the pump as a measure of how much milk you have. A baby who latches well is much more efficient at removing milk than a breast pump. You might only pump two ounces but have a baby who just drank four.
If you have confirmed that your supply is indeed lower than usual, there are several physical factors that could be the cause.
When your period returns, you may notice a temporary dip in your supply. This usually happens in the few days leading up to your period and the first few days of bleeding. It is caused by a drop in blood calcium levels and changes in estrogen and progesterone. For most parents, the supply bounces back once the period is over.
If you become pregnant while breastfeeding, your hormone levels will change significantly. Progesterone rises to support the pregnancy, which can cause a sharp decline in milk production. This often happens even if you are nursing frequently. If you notice a sudden, unexplained drop, it may be worth taking a pregnancy test.
Certain types of birth control can negatively impact milk supply. Specifically, methods that contain estrogen, such as "the pill" or certain patches, are known to decrease production in some people. If you recently started a new form of birth control, consult with your healthcare provider about progestin-only options.
When you are sick, your body uses its energy to fight off infection. Fever and congestion can also lead to dehydration. Since breast milk is mostly water, being dehydrated can make it harder for your body to produce its usual volume. For a deeper dive, see our guide to whether drinking water helps breast milk supply.
Certain over-the-counter medications can "dry up" more than just a runny nose. Medications containing pseudoephedrine, often found in cold and sinus medicine, are known to decrease milk supply. Always check with a lactation professional before taking new medications.
What to do next:
Your environment and daily habits play a huge role in how your body functions. Stress and exhaustion are two of the biggest enemies of a healthy milk supply.
Stress does not necessarily stop your body from making milk, but it can stop the milk from coming out. High levels of cortisol and adrenaline can inhibit the let-down reflex. If you are feeling tense or anxious while pumping or nursing, the milk stays stuck in the ducts. This makes it seem like your supply is low, and over time, it can lead to a true decrease because the milk is not being removed.
We know that "sleep when the baby sleeps" is easier said than done. However, extreme sleep deprivation is a major stressor on the body. Your body needs rest to perform the metabolic work of making milk. Even an extra 30-minute nap can sometimes help your body regulate its hormone levels.
You do not need a perfect diet to breastfeed. However, your body does need enough calories to support both you and your baby. If you are skipping meals or trying to lose weight too quickly, your body may prioritize your own survival over milk production. Focus on nutrient-dense foods like oats, healthy fats, and proteins.
Sometimes, the "why" behind a supply drop is related to the mechanics of how the milk is being removed. If the demand is not communicated clearly to your body, the supply will naturally dwindle.
If a baby is not latched deeply, they cannot compress the milk ducts effectively. This means they are not removing all the milk available. Over time, this signals your body to slow down. If you are experiencing nipple pain or if your baby seems constantly hungry after long sessions, a poor latch might be the culprit. Working with an International Board Certified Lactation Consultant (IBCLC) can help correct this.
As babies get older, they may start sleeping longer stretches. While this is a win for your sleep, it can sometimes lead to a drop in supply if your body isn't used to the long breaks. If you notice a drop after your baby starts sleeping through the night, you may need to add a "dream feed" or a late-night pump session to keep the demand high.
If a baby is given a pacifier to delay a feeding, or if they are given a bottle of formula without you pumping to replace that feed, your body misses out on a signal to produce milk. Every time your baby gets a bottle, your breasts need to be stimulated to maintain the supply-demand balance.
For parents who pump, the equipment matters. If your pump parts (like valves and membranes) are worn out, the suction will decrease. This leads to less milk being removed. Additionally, using the wrong flange size can cause tissue compression, which blocks milk flow. The flange is the plastic funnel that touches your breast; it should fit comfortably without pulling too much of the areola into the tunnel. For more troubleshooting tips, our guide to whether pumping really increases milk supply is a useful read.
Key Takeaway: Your pump is a tool, and like any tool, it needs regular maintenance to function correctly.
Once you have identified the potential cause, you can take action. Most supply drops are temporary and can be reversed with some focused effort.
The simplest way to increase supply is to put the baby to the breast more often. Try a "nursing vacation." Spend a weekend in bed with your baby, doing lots of skin-to-skin contact and offering the breast every 1 to 2 hours. Skin-to-skin contact releases oxytocin, which helps with milk flow and bonding.
Power pumping is a technique designed to mimic a baby’s cluster feeding. It sends a strong signal to your body that it needs to make more milk. To power pump, find one hour in the day and follow this schedule:
If you want a step-by-step version, our power pumping guide breaks it down clearly.
Doing this once a day for 3 to 7 days can often result in an increase in output.
Studies show that using your hands to massage your breasts while pumping can significantly increase the amount of milk you collect. It also increases the fat content of the milk. Use gentle compressions while the pump is running to help move milk from the back of the ducts toward the nipple.
While water is essential, sometimes your body needs a bit more support. We offer several options to help you stay hydrated while providing your body with targeted nutrients. Our lactation drinks, such as Pumpin Punch™ and Milky Melon™, are designed to provide hydration along with ingredients that support lactation.
For those looking for a convenient snack, our Emergency Lactation Brownies are a favorite among our community. They are packed with oats, brewer's yeast, and flaxseed. These ingredients are known as galactagogues. A galactagogue is a substance that may help increase milk production.
Action Plan:
It is important to remember that while many supply issues can be managed at home, some require professional guidance. You should reach out to an IBCLC or your healthcare provider if:
At Milky Mama, we believe that every parent deserves access to expert support. We offer virtual lactation consultations so you can get personalized advice from the comfort of your home, and our Breastfeeding 101 course can help you build confidence with the basics. Sometimes, a small adjustment to your baby's latch or your pumping schedule is all it takes to get back on track.
Many parents turn to herbal supplements when they feel their milk supply is drying up. It is important to choose supplements that are formulated by experts. Our founder, Krystal Duhaney, is a Registered Nurse and IBCLC who carefully selects ingredients that are safe and supportive.
Different herbs work in different ways. For example:
These supplements are often more concentrated than teas or cookies alone. They can be a helpful addition to the "supply and demand" work you are already doing.

We cannot overstate the importance of your mental health in this journey. Stressing about milk supply often creates a cycle that makes it even harder to produce milk. It is okay to feel frustrated. It is okay to cry. But try to remember that your worth as a parent is not measured in ounces.
If the stress of breastfeeding is severely impacting your mental health, please speak to a professional. Sometimes, the best thing you can do for your milk supply is to take care of your mind. Whether that means asking for help with chores, taking a long shower, or talking to a therapist, your well-being matters just as much as the baby's.
Breastfeeding is natural, but it does not always come naturally. It is a learned skill for both you and your baby. Having a support system can make a world of difference.
To recap, if you feel like your milk is drying up, consider these factors:
Key Takeaway: Most supply issues are solvable with frequent milk removal, proper hydration, and the right support.
Finding that your breast milk supply is drying up can feel overwhelming, but in many cases, it is a hurdle you can overcome. By focusing on the fundamentals of frequent milk removal, managing your stress, and ensuring you are nourished, you are giving your body the best chance to recover its production. Remember, every drop counts, and you are doing an amazing job.
If you need more help, we are here for you. Whether it is through our supportive treats, herbal supplements, or a virtual consultation with an IBCLC, the team at Milky Mama is dedicated to helping you reach your breastfeeding goals. You don’t have to do this alone.
Stress does not usually stop milk production entirely, but it can significantly inhibit the let-down reflex. When you are stressed, your body releases adrenaline, which can block oxytocin, the hormone that allows milk to flow out of the ducts. This makes it feel like your supply is gone, and if milk remains in the breast for too long, your body will eventually slow down production.
If your breasts feel softer and you stop leaking, but your baby is still gaining weight and having at least 6 wet diapers a day, your supply has likely just regulated. True low supply is usually accompanied by poor infant weight gain, a decrease in wet diapers, or a significant and sustained drop in pumping output that does not recover after rest.
In most cases, yes, milk supply can be increased again through a process called relactation or by simply increasing the frequency of milk removal. By nursing more often, using techniques like power pumping, and ensuring you are hydrated and nourished, you can signal your body to ramp up production. It may take a few days or even a week to see the results, so consistency is key.
Foods known as galactagogues, such as oats, brewer's yeast, and flaxseed, are often used to support milk production. These ingredients provide essential minerals and B-vitamins that support maternal wellness and lactation. We incorporate these into many of our products to make it easy and delicious for parents to get the nutritional support they need while breastfeeding.
