"Every other massager makes you choose which boob to treat. Why?? They both hurt. Two pads at once was the whole reason I bought MamaWarm."
Tasha O., pair advocate
"I'm not a crier. I cried. The first time I felt cared FOR since the baby came."
Reagan O., first use
Skipped the ER trip
Woke up at 2am with what felt like a softball shoved inside my left breast. I was 100% convinced I was headed to urgent care by morning. Threw these on, fell back asleep, and the lump was gone by 6. I literally cried.
The 2am savior I didn't know I needed
Anyone else been microwaving a rice sock every two hours at night?? Done with that. These live on my nightstand now. Reach over, slide them in my bra, go back to sleep. I am a new woman.
Saved my pumping journey
i was two clogs away from quitting EP at week 10. ordered these out of pure desperation at like 3am. i'm now at 6 months and still going. the clog from hell that used to take me 3 days to clear is gone in like 15 min now. wish i'd had them from the start
Bye Frida 👋
My Frida died after 6 charges. SIX. I was so angry I almost gave up on massagers entirely. Bought MamaWarm as a last resort and the battery actually lasts a full pumping session. Plus there are TWO of them. Why is everyone else selling these one at a time??
I can finally hear myself think
The Momcozy I used to use sounded like a small motorcycle. I pump at work in a literal coat closet (yes really, with the yellow vests) and was constantly paranoid the office could hear it. These are SO quiet I had to check if they were even on the first time. Zoom call safe. Office safe. Sleeping baby safe.
First week back at work
Went back to my hybrid job at 12 weeks and got my first clog within 4 days. Of course. I'd already heard horror stories from other moms in my office. Ordered these the night it started, used them through my morning pump, clog out in about 10 minutes. Output went up too which I wasn't expecting.
Cleared a hot wedge in minutes
That deep hot wedge feeling, IYKYK. I always panicked because I could feel mastitis coming next. With these I can feel the milk start moving in like 6-8 minutes. It's not magic, it's just gentle constant warmth that finally lets your body do what it wants to do.
History of mastitis, never going back
Got mastitis twice with my first. Hospitalized once. The fear of going through that again almost made me not breastfeed my second. My IBCLC told me to invest in a proper hands-free heat pad and not microwave anything. These have been on my body more than my husband has lol. No clogs this round. None.
My husband finally gets it
He's been telling me to 'just give her formula' for weeks. The night I unboxed these he watched me put them in my bra and start pumping with both hands free and just said '...oh.' That was the moment he stopped asking. 😂
Recommended by my LC
My lactation consultant told me to throw out my Frida (literally) because of the new clinical guidelines about not 'digging' at clogs. She recommended MamaWarm specifically because of the flat pad and gentle warmth. I'm not a research-paper mom but I trust her, and these have been a total reset for me.
Best registry add I made
I'm a planner and I added these to my registry because of one Reddit thread that scared me into prevention mode. So so glad I did. Used them from day 2 in the hospital. I've heard the engorgement stories and I haven't had a single one.
Gift for my sister-in-law
My SIL just had her second and was struggling. I sent these because I'd seen them on TikTok and the IBCLC review on bemybreastfriend convinced me. She FaceTimed me crying happy tears two days later. Buying a second pair for my best friend's shower next month.
Day 4 postpartum engorgement = handled
The milk-coming-in engorgement day is no joke. My boobs became actual boulders. Hot, hard, full to the point of crying. Put these on with the heat, sat on the couch nursing, and within an hour I could feel my chest soften. I genuinely think they saved my latch.
EP mom after NICU
My daughter was in the NICU for 11 days and I exclusively pumped from day one without ever really getting to nurse. The clogs were CONSTANT. These have shortened my sessions from 30 minutes to about 18, and I haven't had a clog in over 5 weeks now. The heat is real heat, not lukewarm like other ones.
Quiet on a work Zoom
Took a meeting with my boss with these running under my shirt. He had no idea. The Momcozy I used to use? He would've definitely known. Worth every penny for the dignity alone.
Battery is the real deal
I read so many one-star reviews of other massagers that died after a couple weeks. These have been on heavy rotation for 3 months and still hold a full charge. I charge them every other day at most.
Both sides at the same time, finally
Cannot stress this enough. Every other massager makes you choose which boob to treat. Why?? They both hurt. They're both attached to my body. Two pads at once was the whole reason I bought MamaWarm and it has not disappointed.
Pumping in the parking lot at Target
Mom of 3, no time for a real pump break ever. I pump in my car between school pickup and dance class. Slid these in my bra, drove the carpool, didn't miss a single ounce. They are SO discreet under a regular shirt.
Brought them on a work trip
Three days in Chicago for a conference and I dreaded what pumping in hotel rooms would do to my supply. These came with me, ran on the plane (yes really, under a sweater), and I came home with my supply intact and zero clogs.
Same clog, same spot, every Tuesday. Until now.
I had a recurring clog in the SAME spot for like 8 weeks. Every Tuesday after my long shift it would flare. I'd tried sunflower lecithin, dangle pumping, the whole circus. Started using these preventatively before my Tuesday shift. Three Tuesdays clean.
The razor-blades-through-my-shoulder pain is GONE
Did anyone else get the nerve pain that shoots from your back over your shoulder through your nipple?? No?? Just me?? Anyway it's gone. I think the constant gentle warmth is keeping things moving before it builds up.
Worth every penny
Felt the price at first. $99 felt steep when I'd already spent $130 on two failed Momcozys. Then I did the math. One pair, both sides, no batteries dying in 6 weeks. Easiest decision in hindsight.
Letdown comes way faster
I never get a strong letdown on my pump. I'd be 8 minutes in before anything started. With these on during my pump, I'm getting letdown in like 2-3 minutes. My sessions are noticeably shorter.
I actually slept
Slept four hours in a row last night. FOUR. Because I wasn't waking up every two hours to microwave something. If you're reading this at 2am, just order them.
After abscess recovery, gentle enough
I had a breast abscess at 9 weeks postpartum that required hospitalization. Terrified to ever use a vibrating product again. My doctor said the new guidelines are all about GENTLE warmth (not aggressive vibration) and approved these. They're so gentle they feel like nothing. But they work. Six weeks clog-free.
Replaced my entire cabbage routine
I cannot tell you how done I am with wilted hot cabbage in my bra. The smell. Walking around with leaves falling out of my shirt. These do what cabbage does but better, and my house no longer smells like coleslaw.
Didn't need sunflower lecithin once
Was taking sunflower lecithin every day 'just in case.' Stopped when these arrived. Haven't had a clog. Saved myself $20/month on supplements I don't actually need anymore.
Great product, charger could be better
Love them. Truly. Knocking off one star because the charging cable is a little short and I wish there was a travel case included for the price. But the product itself does what it says.
Discreet on Zoom
Marketing manager, WFH mom, on camera all day. I wear these under a regular cardigan for back-to-back meetings. Nobody sees them, nobody hears them, and my supply hasn't dropped since I started.
Teacher in a 30-min pump window
I teach 4th grade and have ONE 30-minute pump window between specials. Used to barely get 3oz. Now I'm getting almost 5 because letdown happens so much faster with the heat going. Highly recommend for any teacher mom.
ICU nurse, 12-hour shifts
You don't always get to pump on schedule in healthcare. I'd come home with rock-hard boulders every shift. These have been a lifesaver. I put them on the second I get to my car and by the time I'm home I'm comfortable enough to nurse my baby.
Marble feeling, gone in 7 minutes
Felt that little marble under the skin that always turns into a full clog by morning. Threw these on while watching TV. Seven minutes later I could not feel the marble anymore. I'm so relieved.
Twins mom, doing my best
Twin mom here, tandem nursing + pumping, basically a milk factory. The clogs were destroying me. Having TWO pads instead of one is the only reason I'm still breastfeeding both girls at 4 months. Both sides at once is the only way I have time for this.
Tongue tie, then EP
Couldn't get a latch because of his tie. Switched to EP at week 3 and the clogs started immediately. These have made the difference between 'I can do this for a year' and 'I can't do this for another week.' Bless.
MIL was skeptical, now she's a believer
My MIL kept asking why I was spending money on 'fancy things' when she used a hot washcloth in 1987. I let her watch me clear a clog in 9 minutes hands-free while I held the baby. She has been quiet since. 🤐
Output went up 2oz per session
This was unexpected but I'm tracking it: my pump output went up by about 2oz per session on average since I started using these during pumping. I think it's the letdown happening faster + my supply not crashing because I'm not constantly stressed about clogs.
Sliding fit in my pumping bra
I have larger breasts (38G nursing) and these still fit comfortably in my Sublime pumping bra. Was worried they'd be too small. They're not. They're actually really well designed for the curve.
Fit my regular nursing bra
On the other end: I'm a B cup and worried the opposite, that they'd be too big. They aren't. They sit flush. I wear them with my regular bravado nursing bra and they're invisible under a t-shirt.
Honest review: takes time to charge fully
This is mostly a 5-star but full charge takes about 2.5 hours which means I have to remember to plug them in. I just keep them plugged in by the nursery chair now. Product itself is excellent.
Wish it ran 90 minutes instead of 60
Battery lasts a full pump session no problem. But I'd love a longer cycle for the deep engorgement days. Otherwise no complaints. This is the only massager I've kept.
My nursing baby doesn't even notice
I sometimes wear them while my daughter nurses on the other side. She has never once been disturbed by the vibration or the warmth. With my old Momcozy she'd literally pull off and look around because of the sound.
Older sister gifted me these, bless her
My sister had her babies 8 years ago and said she wished she'd had these. Sent me a pair as a 'you're going to need this' surprise. She was right. They were on my body within 6 hours of coming home from the hospital.
My doula recommended them
My postpartum doula put these in my postpartum care plan as 'non-negotiable' prevention equipment. She'd seen too many of her clients spiral into mastitis and ER visits. I'm now in month 3 and clog-free. She knew.
Reddit r/breastfeeding recommended
saw these mentioned in like 4 threads in one week. figured if r/breastfeeding agrees on anything that strongly it has to be real. it's real. order them.
The heat is actually WARM
I tried two cheap Amazon ones before this. They claimed 'heat' but it was like… room temperature at best. MamaWarm actually warms up. You can feel it. That makes the entire difference.
Not a sex-toy-shaped buzzy thing
Look, I tried the 'use a vibrator on it' trick from a forum once. I will not be doing that again. These are designed for the actual anatomy and they are way more effective and way less weird.
Hospital LC recommended over Frida
My hospital lactation consultant specifically told me to avoid the Frida one with the hook end because of the new mastitis guidelines (something about not 'digging' at clogs anymore). She showed me MamaWarm in her cart. That was good enough for me.
Worked through a 6-hour flight
Flew cross-country with the baby at 4 months. Got a clog at hour 3. Slid these in my nursing bra under my hoodie, ran them for two cycles, walked off the plane clog-free. Flight attendants had no idea.
Grandmother bought these for the baby shower
My grandma is 79 and she said 'I wish we had something like this when I had your mother.' She gifted them at my shower. Made me cry then. Has made me grateful every day since.
Going in every postpartum gift basket I make
I make postpartum care baskets for friends having babies. Used to include cabbage leaves, hydrogel pads, lanolin, hot socks. Now MamaWarm is the headline item and I scale back on the rest. Best gift you can give a new mom IMO.
Cried using them the first time
I'm not a crier. I cried. I'd been in so much pain for so long and just sitting on my couch with warm gentle pads working both sides at the same time… it was the first time I felt cared FOR since the baby came. I know that sounds dramatic. I don't care.
Honest mid-review
3 stars because while it does work, the price tag stings and I wish it came with a carrying case. Effectiveness is real. Just feels like at $99 there should be more in the box.
Tried the cheap Amazon set first, regretted it
Bought the $49 NCVI set first because I'm cheap. Battery died in 18 minutes. Returned them. Spent the extra on these and it's not even comparable. Quality difference is enormous.
Pumping bra + MamaWarm = my entire life
I literally have a uniform: hands-free pumping bra, MamaWarm in place, AirPods in, baby in the bouncer. I work, I pump, I parent, all hands free. The two pads at once is the only thing that makes this actually work.
Made it to my 1-year nursing goal
I just made it to 12 months. I genuinely didn't think I would. These got me through three clogs that could've ended my journey early and one near-mastitis scare around month 8. Worth every penny.
Used MamaWarm? Help another mom decide.

● THE BRAND
American moms are doing alone what eight women in every other culture used to do together. No paid leave. No village. No one to bring a warm cloth in the middle of the night. We can't bring the village back, but we could build the smallest possible piece of it. Something warm, quiet, and hands-free that sits in your bed at 2 a.m. instead of you walking to a microwave.

The Single variant ships with 1 pad and 1 cable.
Do not use while charging.
● QUESTIONS
It has multiple heat levels. On the highest setting, the warmth is steady and strong enough to handle a serious clog. For really severe initial-week engorgement, some moms also use ice between sessions. That's exactly what ABM Protocol #36 recommends: ice for swelling, warmth for letdown.
The pads are made to fit inside standard nursing and pumping bras across a wide range of sizes. Check the size guidance on the product page for your specific situation.
Yes. Exclusive pumpers are actually the largest group of MamaWarm users. The pads are designed to use before, during, or after a pump session. They help with letdown, drainage, and the clogs that hit exclusive pumpers more often than nursing moms (because pump output rarely matches what a baby actually needs that day). You can wear them inside any pumping bra, including wearable pumps like Elvie and Willow.
Three differences. First, MamaWarm is sold as a pair, where Momcozy and Frida are sold one at a time. Second, MamaWarm's motor runs 60–90 minutes per charge versus 15–30 minutes for the cheaper options. Third, MamaWarm's design is aligned with the 2022 ABM Protocol #36 (gentle, no hooks or aggressive vibration). Frida's hooked end is now clinically contraindicated. The price reflects that, but so does the difference in what you'll be using at 2 a.m. six months from now.
Per ABM Protocol #36, use ice and ibuprofen first. Rest. If you have a fever, redness, or severe pain, call your doctor. MamaWarm is for the recovery, the prevention, and the next one. Not the emergency tonight.
Yes. A lot of moms buy MamaWarm specifically after their first round of mastitis, as part of their prevention plan. But please note: it is not a treatment for active mastitis. If you have a fever and signs of active infection, call your doctor and start antibiotics. MamaWarm is for comfort, letdown, clog clearance, and ongoing prevention. Not a substitute for medical care when you're actively sick.
Five ways. It's hands-free. It does both sides at once. It's silent. You don't need a microwave or a kitchen trip. And the heat stays warm. It doesn't drop off after 11 minutes. The mechanism is different too. Steady heat plus gentle vibration is doing two things at once, where a washcloth only does one.
It's gentle enough that most babies don't notice at all. In fact, a lot of moms say it actually helps with letdown while nursing. Which means more milk for the baby in less time.
Yes. The heat is body-safe and well-controlled. It stays within the range that traditional postpartum heat therapy has used for centuries, and within the range that ABM Protocol #36 recommends for letdown support.
Plubsy backs MamaWarm with a 60-day money-back guarantee. If it doesn't change your experience in 60 days, send it back. We pay the return shipping. No questions.
Yes. MamaWarm is also available as a single unit at $59 on the product page. The pair is what most moms buy, because you have two breasts and clogs don't take turns. But if you want to try just one first, the single option is there.
Honest answer: we're always low on stock and selling out weekly. Standard shipping is typically 5 to 14 business days, depending on inventory levels and your location. Expedited shipping is available at checkout for $9.99 with the same dependency on stock. We'll email tracking the moment your order leaves the facility.
Two MamaWarm warming massage pads (one for each breast) and two USB charging cables. The Single variant ships with one pad and one cable.
