15 Pumping Tips for Breastfeeding Moms

15 Pumping Tips for Breastfeeding Moms

Whether you’re pumping ‘round the clock, sneaking in a session at work, or setting an alarm for 2 a.m. to keep your supply steady, the mission is the same: keep that liquid gold flowing. Unfortunately, breastfeeding education is already scarce—and pumping guidance is even harder to find. That’s why we’ve gathered our breast—er, best—tips to make every pumping session more productive (and maybe even a little easier).


1. Determine your flange size

When it comes to breast shields, size really does matter. The right flange will make pumping more comfortable, help you express more milk, and optimize your pump’s performance. Most pumps come with a 24mm flange, but that’s just a starting point—measure your nipples and consult a flange sizing guide (like this one from Bodily) to find your best fit. Pro tip: Nipples can change size during postpartum and over the course of lactation, so re-measure every few months.


2. Get to know your pump settings

Most pumps mimic baby’s feeding rhythm with two modes:

  • Stimulation: Short, quick bursts to trigger letdown—just like when baby starts a feed.

  • Expression: Slower, deeper pulls for milk transfer after letdown.

You can switch back to stimulation anytime during a session to encourage another letdown (and more milk). Pro tip: Hands-on pumping—gently massaging and compressing your breasts during expression—can help boost output.


3. Know how to work a manual pump

Electric pumps are great—until the power’s out, the motor dies, or you’re on the go without an outlet. A manual pump like the Medela Harmony (for active pumping) or a Haakaa (for passive milk collection) can be a lifesaver. Learn how to use one before you actually need it.


4. Wear a hands-free pumping bra

A well-fitting pumping bra frees up your hands so you can work, eat, scroll, or massage your breasts while pumping. It can also help keep flanges in the correct position, which will improve comfort and output.


5. Find a cover you love for pumping in public

If you plan to pump on the go—whether that’s in your car, on a plane, or during a quick coffee run—a good nursing or pumping cover can make all the difference. Look for one that’s breathable, offers full coverage without feeling stifling, and is easy to throw on one-handed. Bonus points if it doubles as a scarf or car seat cover for baby. Feeling comfortable and confident while pumping in public can help you relax, which in turn can encourage better milk flow.


6. Create a pumping routine

Your body loves consistency. Pumping around the same times each day can help regulate supply and make sessions more efficient. If possible, mimic your baby’s feeding schedule to keep your body in sync.


7. Warm up before you pump

Applying a warm compress or taking a quick shower before a session can help stimulate letdown and improve milk flow. This is especially helpful for morning pumps or if you tend to feel “slow to start.”


8. Tap into your senses
If you’re away from baby, looking at photos or watching videos can help trigger letdown. Hearing their coos and seeing their smile releases oxytocin—the hormone that helps milk flow.
Pro tip: Keep a blanket, hat, or onesie that smells like baby nearby. Scent is one of the most powerful letdown cues.


9. Stay hydrated and nourished

Milk production takes a lot of water and calories. Keep a large water bottle within reach during pumping sessions, and have easy snacks on hand (here are a few of our favorites)


10. Make it comfortable

Your environment matters—find a comfortable seat, keep your shoulders relaxed, and set up a cozy pumping corner if you’re at home. If you're out and prefer to be covered, choose one that's breathable and offers the coverage you want. A calm, comfortable setting can help your body release more milk.


11. Track your sessions
Use an app or simple notebook to track pumping times, durations, and milk output. This helps you spot patterns, make adjustments, and troubleshoot dips in supply.


12. Replace your pump parts

Pump parts don’t last forever. Over time, valves lose elasticity, membranes wear down, and suction drops. Check your pump’s manual for replacement timelines, and watch for early signs like longer sessions, weaker suction, or squeaky noises. Karrie Locher’s guide is a great reference.


13. Be prepared to store your milk

Once you’re finished pumping, you’ll need to store your breast milk safely. This post breaks down everything you need to know about that. If you pump overnight, keeping a breastmilk chiller like this one on your nightstand can save you a 2am kitchen trip. A cute mini fridge by your bed is totally acceptable, too!


14. Freeze in baby-sized portions

Nothing stings like thawing a 6-ounce bag only to have baby drink half. It may take some trial and error, but figure out their typical serving size (it will change over time) and freeze in those amounts. Pro tip: Freeze milk flat in labeled storage bags—it’ll save freezer space and make thawing faster.


15. Don’t compare
Pumps aren’t babies, and the number of ounces in your bottle doesn’t always reflect your true supply. Direct nursing is more efficient, and some bodies simply respond differently to a pump. Focus on baby’s cues—if they’re growing and content, you’re making enough.
