Have you ever found yourself sitting in a quiet nursery at 3 AM, staring at the plastic parts of your breast pump and wondering if you are doing enough? If you have ever questioned whether your body is producing "enough" or if your baby is truly satisfied, please know that you are not alone. These feelings are some of the most common experiences in early parenthood. We often hear from parents who are concerned that their supply isn’t meeting their baby’s needs, and the first question they usually ask is: "Can you pump to increase milk supply?"
The short answer is a resounding yes. Pumping is one of the most effective tools we have to signal the body to produce more milk. However, while the concept is simple—removing more milk tells your body to make more milk—the practice can sometimes feel overwhelming. There is a lot of nuance to how, when, and why you should pump to boost your production.
In this post, we are going to dive deep into the science of lactation, explore the "supply and demand" nature of our bodies, and provide you with practical, evidence-based strategies to use your pump as a tool for growth. We will cover everything from the mechanics of a "milk order" to advanced techniques like power pumping, and we’ll discuss how to support your body through nutrition and professional guidance. Our goal is to empower you with the knowledge that while breastfeeding is natural, it doesn’t always come naturally—and that is perfectly okay. You are doing an amazing job, and we are here to support you every step of the way.
To answer the question of how pumping increases supply, we first have to understand how our bodies actually make milk. It is helpful to think of your breasts not as storage tanks, but as 24-hour milk-making factories.
In the very early days after birth, your milk supply is largely driven by hormones. The delivery of the placenta triggers a drop in progesterone and a rise in prolactin, which tells your body to begin the transition from colostrum to mature milk. However, after the first week or two, the process shifts from being hormone-driven to being "autocrine" or "removal-driven."
The most important rule of lactation is the law of supply and demand. Every time milk is removed from the breast—whether by your baby nursing or by a breast pump—your body receives a signal. This signal says, "The milk we made is gone; we need to make more to replace it."
When the breasts are full, a protein called Feedback Inhibitor of Lactation (FIL) builds up. This protein essentially acts as a "stop" sign, telling the milk-making cells to slow down because there is nowhere for new milk to go. When you pump or nurse, you remove that milk and the FIL along with it. This removes the "stop" sign and allows your body to ramp up production again.
Two main hormones keep the factory running:
By using a pump, you are essentially "putting in a milk order" for the future. Even if you only see a few drops during a session, you are still sending that vital signal to your brain that more milk is required.
There are several scenarios where a nursing parent might need to use a pump to supplement the work their baby is doing at the breast.
While many parents worry about supply, true medical low supply is less common than perceived low supply. However, it does happen. If a baby has a shallow latch or a tongue tie, they may not be able to remove milk efficiently. This leaves milk in the breast, which, as we discussed, tells the body to slow down. In these cases, virtual lactation consultations can be a lifesaver to help identify the root cause while you use a pump to keep your supply up.
For many, the pump is a bridge between home and the workplace. If you are preparing to return to work, you may want to start pumping once a day after your morning feed to build a small freezer stash. This also helps your body get used to the stimulation of the pump before you are relying on it for every feed.
When babies go through growth spurts, they often "cluster feed," meaning they want to nurse every hour or even more frequently. This is their natural way of increasing your supply. If your baby is fussy or you are feeling overwhelmed, adding a pumping session can mimic this cluster feeding and help your body catch up to your baby's new needs.
If you have decided to use a pump to boost your production, consistency is your best friend. Here is how to set yourself up for success.
Before you even turn the pump on, we need to talk about flanges. The flange (the plastic shield that touches your breast) is not one-size-fits-all. If your flange is too large, it may pull too much areola into the tunnel, causing pain and ineffective milk removal. If it is too small, it can rub against your nipple, causing damage.
An ill-fitting flange can actually decrease the amount of milk you are able to express because your body won't let down effectively if you are in pain. Your nipple should move freely in the tunnel without excess rubbing. Fun fact: your nipple size can change over your breastfeeding journey, so it is a good idea to re-check your fit every few months.
If you are looking to increase supply, using a double electric breast pump is usually more effective than a single pump. Research shows that double pumping (expressing from both breasts at the same time) can lead to a higher prolactin response and more total milk removal. It also saves you a significant amount of time!
Don't just let the machine do all the work. "Hands-on pumping" involves massaging and compressing your breast tissue while the pump is running. This helps to reach the milk-making glands that the pump's suction might not fully stimulate on its own. Many parents find they can increase their output by 20% or more simply by adding breast massage to their routine.
When you are trying to increase supply, frequency is often more important than the duration of the session. It is usually more effective to pump for 15 minutes six times a day than to pump for 45 minutes twice a day.
One of the most effective ways to use a pump to increase supply is a method called power pumping. This technique is designed to mimic a baby’s cluster feeding behavior by repeatedly emptying the breasts over a short period.
To try power pumping, set aside one hour a day. You don't need to do this for every session—just once a day is usually enough to see results over time.
During the "rest" periods, you can drink some water, have a snack, or just relax. Some parents find it helpful to put a sock over the collection bottles so they aren't stressed by watching the milk drip. Remember, this is about the stimulation, not necessarily the amount of milk you see in the bottle during that hour. You are "ordering" more milk for tomorrow.
While the pump is the mechanical tool for supply, your body needs the right fuel to manufacture that milk. Breasts were literally created to feed human babies, but they require a lot of energy to do so!
Breast milk is about 88% water. If you are dehydrated, your body will prioritize your own vital functions over milk production. We recommend keeping a water bottle nearby at all times. If plain water feels boring, our Lactation LeMOOnade™ or Pumpin Punch™ are excellent ways to stay hydrated while also getting a little extra lactation support.
Producing milk can burn an extra 300 to 500 calories a day. This is not the time for restrictive dieting! Focus on whole foods, healthy fats, and complex carbohydrates. Oats, flaxseeds, and brewer's yeast are traditional "galactagogues" (foods that may help increase supply).
If you are looking for a convenient and delicious way to incorporate these ingredients, our Emergency Brownies are a fan favorite for a reason. They are packed with ingredients designed to support nursing parents. We also offer a variety of oatmeal lactation cookies that make for the perfect middle-of-the-night pumping snack.
For some parents, herbal supplements can provide an extra boost. When choosing a supplement, it is important to look for high-quality, professional formulations. We offer several targeted options, such as:

Pumping isn't always a smooth ride. If you are struggling, here are a few common issues and how to handle them.
First, check your pump parts. Valves and membranes are made of silicone and can wear out over time, leading to a loss of suction. If you pump frequently, these parts may need to be replaced every 4 to 8 weeks.
Second, consider your stress levels. If you are tense, your oxytocin may be inhibited, making it hard for your milk to "let down." Try using a warm compress on your breasts for a few minutes before pumping, or look at a video of your baby while you pump.
Soft breasts are actually a sign that your supply has regulated, not that it is gone! In the early weeks, engorgement is common as your body overproduces while it figures out how much your baby needs. Eventually, your body gets more efficient. It stops making "extra" and starts making exactly what is removed. A soft breast is a fast-working breast!
Pumping should never be painful. If it hurts, stop. Check your flange size and ensure your vacuum settings aren't turned up too high. More suction does NOT equal more milk; in fact, it can cause nipple damage that actually hinders production. The "sweet spot" is the highest vacuum setting that is still comfortable for you.
We cannot emphasize this enough: your well-being matters. Breastfeeding and pumping are physically and emotionally demanding. It is okay to ask for help, and it is okay to feel tired.
If you have tried increasing your pumping frequency and are still concerned about your supply, please reach out to a professional. Our online breastfeeding classes are a great way to learn the basics, and a virtual lactation consultation can provide personalized support tailored to your unique body and baby.
You don't have to do this alone. Connecting with other parents who are on the same journey can provide emotional validation and practical tips. We invite you to join The Official Milky Mama Lactation Support Group on Facebook, where you can find a community of supportive, knowledgeable families who understand exactly what you are going through.
Every drop counts. Whether you are providing a full supply, supplementing, or just starting your journey, you are doing something incredible for your baby. Breastfeeding is a relationship, and like any relationship, it has its ups and downs. If you have a bad pumping day, take a deep breath, have a Salted Caramel Cookie, and try again tomorrow. Your worth as a parent is not measured in ounces.
To help you visualize how this works, let's look at a few common scenarios where pumping can make a difference.
Baby Maya is six days old and very sleepy. She falls asleep after nursing for only five minutes on one side. Her mom, Sarah, is worried that her breasts aren't being emptied. The Pumping Plan: Sarah can use a pump for 10-15 minutes after Maya’s short feeds. This ensures her breasts are being stimulated enough to establish a strong supply while Maya works on being more alert during feeds.
Marcus is four months old, and his mom, Elena, noticed that she is getting two ounces less during her work pumping sessions than she was last month. She is feeling stressed and her cycle has just returned. The Pumping Plan: Elena adds one power pumping session in the evening after Marcus goes to bed for five days. She also makes sure to drink a Milky Melon™ drink during her lunch break to stay hydrated and uses Dairy Duchess™ to support her production during her period.
Baby Leo is struggling with a shallow latch, making nursing painful for his mom, Jasmine. They are working with an IBCLC to improve the latch. The Pumping Plan: To protect her supply while they fix the latch, Jasmine "triple feeds." She nurses Leo for a set amount of time, gives him a bottle of expressed milk (using paced bottle feeding), and then pumps for 15 minutes. This is hard work, but it is a short-term strategy to ensure her milk supply is waiting for Leo once his latch improves.

"Breastfeeding is a journey, not a destination. Whether you pump for one month or two years, every drop you provide is a gift of health and love to your baby."
Most parents will begin to see a change in their supply within 3 to 5 days of consistent pumping. However, it can take up to a week for some. The key is to stay consistent with your schedule and not get discouraged if the bottles don't look fuller immediately. Your body is receiving the message, but it takes time to ramp up the "factory" production.
Yes, it is possible to create a "hyper-supply" if you pump excessively when it isn't needed. While having "extra" milk sounds like a good thing, a significant oversupply can lead to issues like frequent engorgement, plugged ducts, mastitis, and a baby who struggles with a very fast let-down. If you are producing enough for your baby and a small daily reserve, you generally don't need to add extra pumping sessions.
No! A pump is never as efficient at removing milk as a healthy, well-latching baby. Many parents have a "normal" supply but find they don't respond well to the plastic and suction of a machine. If your baby is gaining weight well and having plenty of wet and dirty diapers, don't let a low pumping yield convince you that your supply is low.
While a double electric pump is the "gold standard" for increasing supply because it stimulates both breasts and uses a consistent rhythmic suction, manual pumps can still be effective. Some parents find they actually get a better let-down with a manual pump because they have more control over the rhythm. If you are using a manual pump, you will just need to be diligent about switching sides frequently to ensure both breasts get enough stimulation.
Can you pump to increase milk supply? Absolutely. Whether you are navigating a temporary dip, preparing for work, or simply wanting to ensure your baby has every drop they need, the pump is a valuable ally in your breastfeeding journey. By understanding the science of removal, optimizing your schedule, and nourishing your body with the right foods and supplements, you can take control of your lactation goals.
Remember, you are doing an incredible job. Breastfeeding is one of the most selfless acts of parenthood, but it shouldn't have to be a lonely or confusing one. If you are looking for more support, we invite you to explore our Breastfeeding 101 class or browse our collection of lactation treats.
