Choosing the best wearable breast pump for low milk supply can be a game-changer for moms striving to maintain or boost their milk production while juggling busy schedules. Wearable breast pumps offer hands-free convenience, discreet designs, and portability, allowing multitasking without sacrificing efficiency. This guide compiles top picks, detailed pros and cons, real-world testing insights, a buying guide, and a comparison table to help moms make informed decisions.
Why Wearable Breast Pumps Matter for Low Milk Supply
Wearable breast pumps are a “handy option” for on-the-go pumpers, caregivers who need to pump while chasing after older kids, and parents with demanding jobs who can’t count on regular pumping breaks. For moms with low milk supply, a wearable can be strong enough if the supply is established, but those still building supply may need a stronger motor, often found in traditional pumps. Breast milk works in an “on-demand” fashion: Your body produces more milk as needed. It’s best to establish your supply early instead of trying to increase your supply later. If possible, nurse your baby frequently postpartum to establish your supply. To increase supply, you can pump between nursing sessions.
Top Wearable Breast Pumps for Low Milk Supply
1. Elvie Pump
The Elvie Pump is a bag-free wearable pump. You eliminate the need for a flimsy and difficult-to-clean bag. Instead, the pump is connected to a bottle. This makes it much easier to distribute the milk into baby bottles. Plus, it’s easier to clean. Also, the entire unit is wearable, so you can pop it on under your clothes and go about your other tasks. Whether you’re on the go, working, or just doing jobs around the house — the Elvie Pump doesn’t get in the way. In fact, you can pump anywhere you want and nobody will even notice.
- Pros: Wearable under standard nursing bras, nearly silent, hands-free and tube-free, app for tracking sessions and milk output.
- Cons: Quite big, so for petite moms, it can be noticeable. Some customers say that it hurt their nipples, as the suction was strong. The app is the only way to see how long you’ve been pumping, so you need your phone nearby always. The charge sometimes didn’t last a whole day.
2. Willow Go Wearable Breast Pump
I felt very comfortable moving around and washing bottles, brushing my teeth, or making dinner with it on. The Willow Go is a powerful pump, a more-affordable alternative to our top pick, but it’s slightly larger, and it’s more complicated to set up and take apart. The parts feel cheaper to the touch, and there’s no app. But this affordable pump has powerful suction and a comfortable, if awkward-looking, fit. I felt I could do almost anything while wearing it, including lie down, bend over to pick up my baby, or empty the dishwasher. There are two ways to pump with the Willow: directly into Willow’s proprietary pump bags or into their reusable milk containers.
- Pros: Strong suction up to 300 mmHg, leak-proof design, allows freedom of movement, app for controlling settings and tracking output.
- Cons: Too loud for work calls, frequent leaking out the top, no wall charger included, parts must dry completely for a good seal.
3. Momcozy S12 Pro Wearable Breast Pump
The Momcozy S12 Pro is a small, discreet pumping unit that sits entirely inside your bra for a wearable solution. It is lightweight and requires no wires or outlets to work. With a double-sealed flange made from suction-sealed materials, it’s designed so that it doesn’t spill or leak, and the stronger suction seal allows for more efficient pumping, as our parent tester, Gethyn, found. “I would often have difficulty positioning my wired electric pump to be able to get a continuous flow of milk, but the suction on this ensures a strong and regular pump.” Mums loved how the Momcozy S12 Pro gave them a much more affordable alternative to other wearable breast pumps on the market, such as the Elvie.
- Pros: Affordable at under $150, hospital-grade suction at 300 mmHg, double-sealed flange for comfort, three modes and nine intensity levels.
- Cons: Can leak or lose suction if poorly positioned, motor slightly noisier, battery life doesn’t always match the promised 180 minutes.

4. Lansinoh Discreet Duo Wearable Pump
The Lansinoh Discreet Duo is a compact and efficient double electric breast pump designed to fit seamlessly into busy moms’ lives. Its portable, discreet design allows you to pump while going about your daily activities. This pump features nine levels of suction and four pumping modes, delivering a powerful suction strength of up to 260 mmHg to maximize milk expression. It includes leak-resistant six-ounce reusable breastmilk collection cups and comes with two flange sizes (21 mm and 24 mm). The LED display screen ensures easy reading, even during nighttime feeds. Not only was this one of the most comfortable breast pumps I’ve ever used, with no discomfort even on the higher power settings, it also yielded the same amount of milk I get from my standard electric breast pump!
- Pros: Comfortable even at higher settings, often covered by insurance, stable design prevents spills, lightweight at 170g.
- Cons: Less suction power than competitors (260 mmHg), flange sizing can be tricky, not as discreet under tight clothing.

5. BabyBuddha Portable Breast Pump 2.0
In May 2025, BabyBuddha introduced the BabyBuddha Portable Breast Pump 2.0. This pump has the same unique pull patterns (and sleek, lightweight design), but it now features a new “Soft Stimulation Mode” with six settings, offering a slightly lower suction range. Because of these updates, our tester said it’s her favorite pump so far—comfortable, improves supply, portable, and relatively quiet. Though the BabyBuddha pump is more portable than our other picks in this guide, the 1-pound BabyBuddha is not a true wearable pump since it requires the use of a pumping bra to hold its traditionally shaped flanges in place, while its control unit and tubing hang from the neck via a lanyard.
- Pros: 21 levels of suction/control, high yield, lightweight at 1 pound, soft stimulation mode for comfort.
- Cons: Not a true wearable (requires pumping bra), louder at 42 dB, suction can be too strong during letdown phase.

Testing Scenarios and Performance Insights
We tested the top 10 breast pumps from Spectra, Medela, Baby Buddha, Elvie, and more to find the most efficient and comfortable options. Our exhaustive and detailed testing process provides you with the critical information needed to make a well-informed decision. We meticulously examined various metrics and completed more than 25 individual tests per breast pump. With test results and breastfeeding mom input, we score and rank products to award our top picks.
Real-World Testing Feedback
- Elvie Pump: One of our lactating moms said, “I loved this pump, it was comfortable and pumped so quickly I was done in half the time as other pumps.” However, our tester Veronica noted, “I wasn’t rushing to pump again after being engorged.” The Elvie Stride, a related model, only expressed 0.12 oz/min in tests, indicating lower efficiency for some users.
- Willow Go: Our tester loved the easy-to-read LCD screen on this pump. They appreciated that they could look down at any moment and know which mode was selected, the current suction level, and how long they’d been pumping. The Imani i2, a similar wearable, was unique for its leak-proof design, which meant testers could go about their day without worrying about spillage.
- Momcozy S12 Pro: Mum Jess commented, “90% of the time, it’s great. Sometimes it does lose suction, and I have to hold it again, but this is only if I move too much and dislodge it.” Another tester, Gethyn, found the suction ensured a strong and regular pump, unlike wired electric pumps.
- Lansinoh Discreet Duo: Testers noted this pump was intuitive and had customizable settings, but was also tricky to put on your breasts and had a disappointing battery life. Assembling the Lansinoh Discreet Duo was straightforward, but some wearable pumps can be fiddly since you need to line them up just right to ensure they’re properly sealed to avoid leaks.
- BabyBuddha 2.0: Our tester states, “I found the Buddha latched well, with fewer adjustments for the best performance.” It also has a relatively wallet-friendly price. However, our lactating moms found the suction power too strong during the letdown phase, which can be uncomfortable for sensitive breasts or nipples.
Buying Guide for Wearable Breast Pumps
Before you randomly pick a breast pump based on a friend’s recommendation, remember that you both might be looking for very different things. We’re all on different paths in life, with different bodies, different babies, and different sets of goals and obstacles. Here’s how to choose the right wearable breast pump for low milk supply:
- Suction Strength: People that are trying to boost their milk supply may need a hospital-grade pump that sucks faster and at a higher frequency, whereas others fare well with a standard pump. Suction is usually measured in “mmHg” and ranges from around 220 to 350, which is the highest level available.
- Flange Fit: The size of the flanges makes a huge difference. Finding the right fit for a wearable pump may be trickier since the pump is hidden inside the bra, making adjustments more difficult. “Flange sizing is more challenging because you can’t see anything,” says Tolman.
- Battery Life: We want our portable pumps to be the ¡®just right’ level of convenience. This means making sure the length of the battery life is sufficient for the time that person may need to pump during the day, and that parts are easy to wash and replace.
- Portability and Discreteness: A wearable pump can work really well for moms who need something discreet. If you’ll be pumping in public view, opting for something that’s practically invisible may be worth the price.
- Insurance Coverage: In January 2025, Lansinoh announced the DiscreetDuo. It’s advertised as being the first-ever wearable breast pump available for free—meaning without upgrade fees—through most insurance plans, including Medicaid. Before you deliver, call your insurance company to ask for guidance on getting a covered breast pump.

Frequently Asked Questions
Are wearable breast pumps effective for low milk supply?
Yes, hands-free breast pumps are effective, but results may vary from person to person. Many models are designed with advanced technology to mimic a baby’s natural sucking pattern, promoting efficient milk expression. For moms with low milk supply or those still establishing their supply, a wearable can be strong enough, but a traditional pump with a stronger motor may be more effective.
Can I use a wearable pump as my primary pump?
Wearable pumps are best suited for moms who need flexibility in their routines—the main benefit they offer is portability and convenience. “One of my favorite uses for a wearable pump is if a mom is struggling to keep up her pumping schedule. A wearable pump can be a nice supplement to help fill in the gaps,” says Tolman. However, they may not offer the same level of suction or milk output as larger, traditional pumps.
How do I ensure a proper fit with a wearable pump?
The size of the flanges makes a huge difference. Working with a lactation consultant can help you know for sure if your breast pump fits well, and online resources, such as YouTube instructions or manufacturer websites, can be helpful, too. Some pumps are easier to determine fit than others, though. “If you’re trying to get a good fit and see how the pump is operating on you, [many] wearable pumps don’t allow you to see the nipple move when the pump is operating,” says Luczywo.
What should I do if my wearable pump leaks?
Getting the right seal between nipple and pump can be tricky. Practice sealing the flange around the milk receptacle before you first pump. For example, with the Momcozy pump, once Coco found a quick and reliable way to pull the lip over the edge of the cup, she never had an issue again. Ensure parts are completely dry between sessions to maintain a good seal.
Conclusion
Wearable breast pumps like the Elvie Pump, Willow Go, Momcozy S12 Pro, Lansinoh Discreet Duo, and BabyBuddha 2.0 offer moms with low milk supply the flexibility to pump discreetly while managing daily tasks. Each model has unique strengths, from the Elvie’s silent operation to the Momcozy’s budget-friendly price. By considering suction strength, flange fit, battery life, and insurance coverage, moms can find the perfect pump to support their breastfeeding journey.
