What Is Power Pumping?

Published: March 26, 2026

Power pumping is a popular strategy to increase your milk supply that mimics baby’s frequent feedings during a growth spurt or cluster feeding phase. Our pediatric pros explain how power pumping works and how to fit it into your schedule.

Key Points

✔ Power pumping can boost your milk supply

Power pumping sends a strong signal to your body to produce more milk just like a baby does when they are frequently feeding or cluster feeding. 

✔ Power pumping is a short-term strategy

Most parents try power pumping once a day for 3 to 7 days, and if supply improves, they return to their regular schedule. 

✔ Your well-being matters just as much as your milk supply

Power pumping can be physically and emotionally demanding. If power pumping increases stress, exhaustion, or pain, there are other ways to boost your milk supply. 

How Power Pumping Works

Power pumping involves pumping in short intervals for an hour or so, with rests in between each pump, and continuing this pattern for a few days. The repeated pumping signals to the brain that “baby needs more milk” and the body typically responds by producing more over time. 

A common power pumping pattern looks like this:

Power pumping happens in addition to your regular pumping or nursing sessions, and the goal isn’t to get more milk in the moment —it’s to more fully empty the breasts, and to send a signal to your brain that you need to increase milk production. The frequency of power pumping mimics cluster feeding, when a baby feeds frequently over a short period of time. 

Why Power Pumping Works

Milk production works on a supply-and-demand system. Each time your breasts are emptied, your brain releases a hormone telling your breasts to make more milk. The more frequently milk is removed, the more milk the body is signaled to make. That means if your milk supply is low, or you’re trying to increase your milk supply, power pumping can be the signal your body needs to increase production. 

Power pumping typically works because it:

This extra stimulation typically helps the body recalibrate and increase overall milk production within a few days.

When to Try Power Pumping

Power pumping can be helpful when supply is genuinely low—or when the body needs a stronger signal to increase production. Parents often try power pumping when:

Power pumping is not always necessary, and it is just one of several ways to increase your milk supply. We do not recommend power pumping if you are feeling physically or emotionally exhausted, stressed or anxious about your milk output, or if your nipples are sore from pumping or nursing. Power pumping can potentially worsen these feelings. 

To decide if power pumping is right for you, ask yourself: 

Power pumping is not a failure-proof solution, and choosing not to do it—or stopping—is not giving up. If you’re unsure whether power pumping is necessary or effective for you, a lactation consultant can help assess supply and make a personalized plan.

How to Power Pump

Step 1: Plan for it 

Power pumping is usually effective when it happens consistently for a few days. You’ll need around an hour each day to power pump. You don’t need to power pump at the same time each day, but doing so can help to establish a routine. 

Step 2: Set up 

Settle into a chair or spot where you will feel comfortable for the hour that you’ll spend pumping. Keep supplies nearby, like your water bottle, favorite snacks, phone/remote, charger, and lubrication for the flange. Make sure you are using the correct flange size for your nipples. If possible, use a comfortable double electric pump for efficiency and ease on your hands.

Step 3: Begin pumping

Begin pumping. Pump for 10 to 20 minutes, then rest for 10 minutes and begin again. Repeat once or twice, then end the power pumping session for the day and safely store breast milk for later.

Continue power pumping once a day for 3 to 7 days, then return to your regular pumping schedule. 

Tips for Success

Power Pumping Schedule 

We recommend replacing one of your regular pumping sessions with power pumping. The best times of day to power pump are typically in the early morning (when there is more prolactin in your breast milk), after nursing, and before bed when you are feeling relaxed. Many parents choose to power pump when baby is reliably settled, such as after their morning nap.

If baby nurses shortly after a power pump, your body will still produce milk. Frequent stimulation—not “saving” milk—leads to an increase in your milk supply.

How to Tell If Power Pumping Is Working

You will know power pumping is working if your breasts feel lighter after pumping and you notice an increase in your total daily milk output. You may also notice that you need to pump less frequently to get the same output—a sign your body is producing more milk.  

You do not need to see large volumes of breast milk at each interval when power pumping. The benefit comes from the signal that pumping sends to your body, not the immediate output. 

When to Continue and When to Stop Power Pumping

Alternatives to Power Pumping

If power pumping isn’t working for you, there are other strategies to try, like more skin-to-skin time with baby or adding just one extra pumping session each day rather than power pumping for a whole hour. Often, small adjustments made consistently can be just as effective—and far more sustainable. Learn more about how to increase your milk supply.

Frequently Asked Questions

What is the best time to power pump?

This will depend on your schedule but aim for a stretch between feedings when you expect baby to take a longer nap, or between other pumping sessions. For some, the first thing in the morning when milk production is high and your breasts are ready to be emptied works well, for others before bed when baby is asleep and won’t likely be coming to the breast immediately after is best. 

Is it better to pump in the morning or evening?

Because it can be quite challenging to fit in a power pumping session between other pumping sessions or your usual breastfeeding sessions, it is best to add a power pumping session whenever it works for your day. That said, you might be able to collect more milk in the morning due to naturally higher prolactin levels at that time of day and potentially a longer stretch between pumping or nursing sessions through the night.    

How can I fit power pumping into my routine? 

Because power pumping is meant to be a short term strategy (for no more than a week or two) you may need to shift around your typical pumping or nursing routines a bit or vary the times of day when you do a power pumping session to accommodate when baby actually eats (vs when you expected baby to eat). Sometimes it is possible to simply replace a single pumping session with a power pumping session, which can be your new routine during the power pumping trial. 

What’s the reason to stop power pumping if it’s working? 

Power pumping can be very effective for some and if it is working for you, you may wonder when or why to stop. While there is no firm rule that you must stop after a certain number of days, once your milk supply has increased and is matching the volume you need, continuing to power pump can potentially lead to oversupply or nipple damage from so much stimulation. Power pumping is also intensive and can be exhausting, so once supply is up, it’s ideal to go back to usual pumping to see if this is sufficient to sustain your supply. 

Does power pumping always work? 

No, power pumping does not work for every parent. Low milk supply can be caused by a number of issues, some of which cannot be fixed by more pumping or attempts to empty your breasts. This is why we suggest doing a short trial of a few days and discontinuing power pumping if you are not seeing any difference in your supply.  

Is power pumping worth it? 

Power pumping can be very effective for some people, helping them get their supply up and meet their goals. For others, even if it is effective, the impact from the effort it takes to add in power pumping can outweigh the benefits. Only you can decide if power pumping is worth the extra time, energy, and effort it takes.
