Sitting down with a breast pump for the first time can feel like being handed a complex piece of machinery without an instruction manual. You might find yourself staring at the bottles, wondering if you should stop after five minutes or keep going for thirty. It is a common source of anxiety for many parents. You want to make sure your baby has enough milk, but you also do not want to spend your entire day tethered to a wall outlet.
At Milky Mama, we know that every drop of liquid gold represents your hard work and dedication. We were founded by Krystal Duhaney, a Registered Nurse and International Board Certified Lactation Consultant, to ensure you have the clinical expertise and emotional support needed to reach your feeding goals. If you want personalized help beyond this guide, our Certified Lactation Consultant Breastfeeding Help page is a good place to start. This guide will help you understand exactly how long you should spend in each pumping session based on your unique needs. Whether you are returning to work or exclusively pumping, we want to help you find a rhythm that feels sustainable.
The answer to how long you should pump depends on your goals, your baby’s age, and how your body responds to the pump. Finding the right balance between time and frequency is the key to maintaining a healthy milk supply while protecting your physical and mental well-being.
For most people, a standard pumping session should last between 15 and 20 minutes. This timeframe is usually sufficient to stimulate a let-down and remove the majority of the milk stored in the breasts. A let-down is the physiological reflex that causes milk to flow from the small sacs in your breasts into the milk ducts.
If you are using a double electric breast pump, you are pumping both sides at once, which makes this 20-minute window very efficient. If you are using a manual or single electric pump, you will need to spend 15 to 20 minutes on each side. This means a single-sided session could take nearly 40 minutes total. Efficiency is one reason many lactation professionals recommend double pumping for anyone who needs to express milk frequently.
Your body needs time to receive the signal that it is time to release milk. The first few minutes of pumping often involve faster, lighter suctions that mimic a baby’s initial hungry nibbles. Once the milk starts flowing, the pump usually switches to a deeper, slower rhythm.
Most of the milk is typically removed in the first ten minutes. However, those last few minutes are crucial for signaling your body to keep up production. Pumping for a few minutes after the milk flow has slowed to a trickle tells your brain that more milk is needed for the next "feed." This demand-and-supply cycle is the foundation of a healthy lactation journey.
It is important to remember that the clock is not the only thing that matters. The "quality" of your session involves how well the pump is removing milk. If you pump for 30 minutes but have the suction set so low that nothing is coming out, the time spent is not helpful. Conversely, if you pump for 10 minutes and feel completely soft and drained, you may not need to force yourself to hit the 20-minute mark every single time.
Key Takeaway: For a typical session, aim for 15 to 20 minutes with a double electric pump. Focus on how your breasts feel rather than just the number on the timer.
Your reason for pumping significantly changes how long and how often you should use your device. A parent who is only pumping once a day to have an extra bottle on hand has different needs than a parent who is exclusively pumping. If that sounds like you, our How to Increase Milk Supply with Exclusive Pumping guide may help you fine-tune your routine.
If you are exclusively pumping, your pump is your baby’s primary way of getting milk. In the early weeks (the first 12 weeks postpartum), you should aim to pump 8 to 12 times in a 24-hour period. Each of these sessions should last about 15 to 20 minutes.
Consistency is vital during this stage because your milk supply is still being established. You are essentially mimicking the feeding patterns of a newborn. As your baby grows and your supply regulates, you may be able to slowly decrease the frequency of your sessions while maintaining the 20-minute duration.
When you are away from your baby, the goal is to replace the feedings you are missing. If your baby typically eats every three hours, you should try to pump every three hours. Most working parents find that three sessions of 15 to 20 minutes during an eight-hour shift help them keep their supply steady.
If you find that you are not getting enough milk for the next day's bottles, you might consider extending your sessions by five minutes. However, focus more on the frequency of the sessions rather than making one session last for an hour. Frequent, shorter removals are better for supply than one long removal.
If you are nursing your baby and just want to save a little extra milk, you do not need to pump for long. Many parents find success by pumping for 10 to 15 minutes after the first morning nursing session. This is typically when milk volume is at its highest.
If you are only looking for an ounce or two a day, a short session is perfect. You do not want to over-pump and create a massive oversupply, which can lead to discomfort and issues like mastitis (an inflammation of the breast tissue).
If you are concerned about your supply, you might be tempted to sit at the pump for an hour. This is generally not recommended. Instead, you can try "power pumping," which we will discuss in more detail later. For a standard session aimed at increasing supply, 20 to 25 minutes is usually the limit. You want to pump until the milk stops flowing, then continue for about two minutes of "dry pumping" to signal for more production.
To understand why 15 to 20 minutes is the standard, it helps to know what is happening inside your body. Milk production is a continuous process, but milk removal happens in "waves."
Many parents assume they only have one let-down per session. In reality, you can have multiple let-downs. You might see a big spray of milk in the first five minutes, then a lull where only drops appear, and then another "rush" at the 12-minute mark.
If you stop as soon as the first rush ends, you might be leaving significant amounts of milk behind. This is why staying on the pump for a full 15 to 20 minutes is helpful. It allows your body to potentially trigger a second or even third let-down, which often contains milk with a higher fat content.
You may hear people say they need to pump until they are "empty." In truth, your breasts are never truly empty. They are like a river, not a lake—the milk is constantly being produced. However, you can reach a point of "drainage" where the flow slows significantly and your breasts feel soft.
This softness is a signal to your body to speed up production. When the breasts are full, the body receives a signal to slow down. By pumping for a consistent 15 to 20 minutes to reach that softened state, you keep the "milk factory" running at peak efficiency.
While it might seem like more time equals more milk, there is a point of diminishing returns. Pumping for too long can actually be counterproductive.
Most lactation experts recommend not exceeding 30 minutes in a single session. Pumping for 40, 50, or 60 minutes straight can lead to several problems:
If you find that you have to pump for 40 minutes just to get a few ounces, the issue is likely not the time. It might be your pump settings, your flange size, or your hydration levels.
You should feel comfortable ending your session when:
If you are looking to boost your supply, you might have heard of a technique called power pumping. This is a specific strategy designed to mimic a baby’s cluster feeding. Cluster feeding is when a baby wants to nurse very frequently for a few hours to tell the body to ramp up production. You can also read more about this approach in our How Long Should I Pump to Increase My Milk Supply? guide.
Instead of one long, grueling session, power pumping breaks the time into segments. A typical power pumping hour looks like this:
This total hour of "on and off" stimulation is much more effective than pumping for 60 minutes straight. It provides repeated signals to your body to release prolactin, the hormone responsible for milk production. You usually only need to do this once a day for three to seven days to see an increase in your supply.
If you want to make your 15 to 20 minutes as productive as possible, there are several things you can do to support your body. Milk removal is not just about the machine; it is a hormonal process.
Stress is the enemy of the let-down reflex. If you are hunched over, worrying about the clock, or feeling cold, your body may struggle to release milk.
Using your hands to gently massage your breasts while you pump can significantly increase the amount of milk you remove. This technique, often called "hands-on pumping," helps move milk from the back of the breast toward the nipple. It also helps you identify any firm areas that might need a little extra attention to prevent clogged ducts.
If your pumping sessions are taking forever, your equipment might be the culprit.
Pumping is hard work for your body. You are burning extra calories and losing fluids every time you sit down to express milk. To support your production and ensure your sessions are effective, you must stay hydrated and well-nourished.
Many parents find that specific ingredients help support their lactation goals. Oats, brewer's yeast, and flaxseed are classic choices. We offer a variety of ways to incorporate these into your routine. Our Pumpin Punch™ is a delicious way to stay hydrated while enjoying ingredients that support lactation. For a quick snack between sessions, our Emergency Brownies are a favorite among our community. They are designed to be a convenient, tasty treat that fits into your busy schedule.

Sometimes, despite your best efforts, your pumping time does not seem to align with your output. Here is how to handle a few common scenarios.
If this is happening, first check your pump parts. If the parts are fine, you might be struggling with your let-down. Try to relax, use heat, and look at photos of your baby. If you are recently postpartum, remember that it takes time for the milk to "come in" fully. If your baby is older and this is a new change, it might be due to stress, a change in your cycle, or a need for more calories and hydration.
Some people have a very high capacity or a slower flow. If you are still seeing a steady stream of milk at the 20-minute mark, it is okay to keep going for another 5 to 10 minutes. However, try to avoid going past 30 minutes regularly. If you always have a lot of milk left, you might need to check your pump's suction strength or try more hands-on massage during the session.
It is completely normal for your breasts to behave like "sisters, not twins." One side may produce more milk or release it faster than the other. If one side is done at 12 minutes and the other is still going at 20, you can turn off the suction on the finished side (if your pump allows) or just let it continue with the "dry" stimulation while the other side finishes.
Key Takeaway: Flexibility is important. While 15 to 20 minutes is the goal, your body may occasionally need a little more or a little less time. Listen to your physical cues over the timer.
Pumping can feel like a chore, but it is also a powerful tool that gives you freedom and flexibility. Whether you use that 20 minutes to catch up on emails, scroll through photos of your little one, or simply sit in silence with a snack, try to view it as a dedicated time for you and your baby's health.
Remember that your worth as a parent is not measured in ounces. Whether you pump half an ounce or eight ounces, you are doing an incredible job providing for your child. Every drop counts. If you find yourself struggling, do not hesitate to reach out for support. Our team and the Milky Mama community are always here to offer a virtual hug and evidence-based advice.

Determining how long you should pump for breastfeeding is a journey of discovery. For most, the magic number is 15 to 20 minutes per session. This allows for multiple let-downs and ensures the breasts are well-drained to signal continued production. Remember to avoid the "marathon" sessions of 30+ minutes to protect your nipple health, and use techniques like power pumping only when you need a specific boost.

If you are exclusively pumping for a newborn, aim for 8 to 12 sessions in a 24-hour period to mimic a baby’s feeding pattern. If you are nursing and just pumping to build a stash, one or two sessions a day is usually plenty. For those at work, try to pump every 3 hours or whenever your baby would normally eat. If you want more help tailoring that schedule, the Practical Tips for How to Increase Milk Supply While Pumping guide is a helpful next read.
If you are in a rush, a 10-minute session is better than skipping a session entirely. While you might not get as much milk or trigger a second let-down, you are still providing the necessary stimulation to your body to keep producing milk. However, try not to make 10-minute sessions your regular habit if you are trying to maintain a full supply.
You should pump until the milk flow has slowed down to a very slow drip, which usually takes about 15 to 20 minutes. You do not need to wait until the breast is "bone dry," as milk is always being produced. Continuing for about two minutes after the flow slows is a great way to signal your body to make more for next time.
Pumping every hour is usually too taxing on your body and your nipples. Instead of pumping every hour, many lactation consultants recommend "power pumping" once a day. This mimics cluster feeding by using a specific 60-minute cycle of pumping and resting, which is more effective and less likely to cause tissue damage than hourly pumping.
