A $13 piece of silicone shouldn't be this life-changing. But when you realize how much milk you've been losing to nursing pads and burp cloths, a Haakaa starts to feel less like a purchase and more like a rescue operation for your freezer stash.
Whether you're exclusively pumping, combo feeding, or juggling a pump bag and a diaper bag on your way out the door — this is the Haakaa walkthrough you actually need. Attachment technique, model comparison, the Epsom salt clogged duct trick, and a colostrum collection section that most guides skip entirely.
What Is a Haakaa (and How Is It Different from an Electric Pump)?
One piece of silicone. No batteries, no cords, no flanges to assemble. You squeeze the Haakaa, flip the rim onto your breast, let go, and suction does the rest.
Calling it a “pump” is misleading, though. Your Spectra S1 or Medela Pump In Style actively extracts milk with rhythmic suction cycles. A Haakaa just catches what's already flowing — your letdown reflex does the real work. Think collection cup with a slight assist, not pump.
Why that matters: when you nurse or pump one side, the opposite breast lets down too. Oxytocin triggers both simultaneously. Without a collector, that milk soaks into a nursing pad. With a Haakaa on, you capture 1–3 extra ounces per session — milk that was leaving your body anyway.
Over a week, that's a freezer stash building itself while you sit on the couch half-watching a show you won't remember the plot of tomorrow.
The Haakaa came out of New Zealand and became a cult favorite because it's $12–15 and virtually indestructible. No parts to lose in the dishwasher. No motor to die at 3 AM.
Which Haakaa Should You Get? (Original vs Ladybug vs Gen 3)
The original Haakaa is all most people need. But the lineup has grown, so here's the short version.
Haakaa Original (Gen 1/Gen 2) — 100ml or 150ml. One piece of silicone, a flared rim, done. The 150ml is the more popular size. Cheap, effective, zero learning curve.
Haakaa Gen 3— wider suction base so it actually stands upright (parents of grabby babies, this one's for you), a silicone plug to cap the top, and an anti-colic nipple attachment. A few dollars more than the original.
Haakaa Ladybug — entirely different shape. Low-profile, sits inside your bra like the Elvie Curve. Holds 75ml and catches passive leaking all day, not just during letdowns. Less collection per use, but discreet enough for the office.
Ladybug vs Elvie Curve: the Curve holds more (4 oz vs 2.5 oz), fits more body types, and costs 2–3x as much (~$50 vs ~$20). Both are passive collectors.
Starting out? Get the original 150ml. Add a Ladybug later if you need something for on-the-go.
How to Attach a Haakaa: Step by Step
A poorly attached Haakaa slides off, collects nothing, and deposits 2 oz of milk directly onto your shirt. The seal is everything.
The squeeze-flip-release method:
- Hold the Haakaa upside down with the flange (wide rim) facing up and the bulb at the top.
- Squeeze the bulb firmly with one hand to push out most of the air. Keep squeezing.
- Flip the flange back — fold the rim outward, almost inside-out. This gives you better access to position it.
- Center over your nipple and press against your breast. Your nipple should sit in the neck of the Haakaa, not smashed against the side.
- Release the squeeze slowly. The suction pulls the Haakaa onto your breast and draws your nipple into the neck.
- Flip the flange back up so it sits flat against your skin, creating a full seal all the way around.
- Squeeze the bulb once moreif you want slightly stronger suction — but don't overdo it. Too much suction causes discomfort or pulls in areolar tissue.
Two things that trip people up: nipple cream (especially lanolin) weakens the seal — pat dry first. And angle the Haakaa slightly downward so gravity pulls milk into the bulb instead of pooling at the flange.
If suction feels painfully strong, break the seal with a finger at the rim and reattach with a gentler squeeze. You're not trying to vacuum-seal yourself.
How to Use a Haakaa While Nursing or Pumping
Most common setup: Haakaa on the opposite breast while baby nurses. Your baby triggers a bilateral letdown — both sides release simultaneously — so the Haakaa catches what your non-nursing side produces.
During nursing: Latch baby on one side, attach the Haakaa to the other with squeeze-flip-release, and leave it. Most moms collect 1–3 oz, sometimes more during morning feeds when supply peaks. Your only job is to stop your baby from kicking it off. (They will try. They will eventually succeed.)
During electric pumping: Single-pumping with a portable like the Elvie Stride or BabyBuddha? Haakaa on the other side catches the sympathetic letdown — a way to increase your milk output without doubling pump time.
One thing to keep straight: the Haakaa doesn't replace active pumping for supply maintenance. It catches overflow — it doesn't send the “empty the breast” signal that a pump or baby does. The feedback inhibitor of lactation (FIL), a protein that regulates production, responds to how thoroughly the breast is drained. Passive collection doesn't trigger the same “make more” response.
How Long Should You Leave the Haakaa On?
Ten to fifteen minutes, or until milk stops flowing — whichever comes first.
Most letdowns last 2–5 minutes, but a second letdown often follows several minutes later. La Leche League notes that multiple letdowns per session are normal — leaving the Haakaa on for the full feed captures both waves.
No harm in leaving it on longer. But once the milk stops, you're just wearing a silicone suction cup for no reason — and giving your baby time to discover it's a fun thing to grab and launch across the room.
For clogged duct use, timing is different — see the Epsom salt section below.
Using a Haakaa as an Exclusive Pumper
If you're exclusively pumping, the Haakaa won't replace your electric pump — but it fills in the gaps between sessions in a way nothing else does.
Between pump sessions:random letdowns happen. (Your body hears a baby cry on TV and decides it's go time.) Attach the Haakaa and catch what comes. Half an ounce here and there adds up to 2–4 extra oz per day without any additional time connected to your pump.
During single-side pumping: Haakaa on the non-pumping breast. Works well if your exclusive pumping schedule includes single-pump sessions to give yourself a break from double pumping.
For freezer stash building:this is where the Haakaa earns cult status. Use it every feed or pump session for the first 6–8 weeks, freeze everything collected, and you'll have a solid backup before you return to work. One mom in a breastfeeding community reported collecting 100+ ounces in her first 3.5 months — all from a Haakaa during regular nursing sessions, no extra pump time.
“I was getting maybe 1.5–2 oz per session, three times a day. Didn't feel like much at the time. Then I counted and realized I'd banked over 130 oz in a month without a single extra pump session.”
— paraphrased from r/breastfeeding
If you're also working on supply, combine Haakaa collecting with a power pumping schedule. The power pumping signals your body to produce more; the Haakaa captures the overflow.
How to Use a Haakaa for Clogged Ducts (Epsom Salt Method)
Fill a Haakaa one-third full with warm (not hot) water and 1–2 tablespoons of Epsom salt, then attach it over the clogged area. Warmth, magnesium sulfate, and gentle suction work together to draw out the clog.
- Warm water in the Haakaa — comfortable bath temperature, not scalding.
- Add 1–2 tablespoons of Epsom salt. Swirl to dissolve.
- Lean forward and attach over the affected breast, centering on the clogged area.
- Leave it on 10–20 minutes. You may see milk strands, fatty clumps, or small clots release into the water. (Satisfying but gross — very on brand for postpartum life.)
- Remove, discard the salty water, then nurse or pump to fully drain.
Throw out any milk from an Epsom salt soak.The salt isn't safe for baby.
“Third clog in two weeks and I was ready to cry. Did the Haakaa Epsom salt thing as a last resort before calling my LC. Watched a thick stringy plug float out into the water. The relief was instant.”
— paraphrased from r/ExclusivelyPumping
Many lactation consultants recommend this as a first-line home approach. The Academy of Breastfeeding Medicine's 2022 mastitis protocol shifted away from aggressive deep massage toward gentler interventions — making the Haakaa soak more aligned with current guidance. That said, some newer IBCLC voices argue that clogs are inflammation, not literal plugs, and that additional suction may aggravate things. If this method doesn't help after two tries, stop and call your provider rather than escalating.
If the clog doesn't resolve within 24–48 hours, or you develop fever, spreading redness, or flu-like symptoms — those are mastitis signs, not just a stubborn clog. Contact your healthcare provider. You might also find relief from cabbage leaves for engorgement while waiting for it to clear.
Can You Use a Haakaa to Collect Colostrum?
Yes — and it's one of the most underrated uses.
Prenatal colostrum harvesting(starting around 37 weeks with your provider's OK) means expressing small amounts of colostrum before birth and freezing it in syringes — a backup if latching is difficult or baby needs supplementation early. A 2023 feasibility study found 72% of participants who learned antenatal hand expression practiced it successfully at home.
The Haakaa's gentle suction encourages flow without the aggressive extraction of an electric pump (not recommended prenatally). Some moms find it pulls colostrum more efficiently than hand expression alone, though results vary. Collect into the Haakaa, then syringe-transfer into freezer-safe storage.
Postpartum(first 2–3 days): Haakaa on the opposite breast while baby nurses. Volumes are small — colostrum comes in drops, not streams — but every milliliter matters when your newborn's stomach is the size of a cherry.
On a newborn pumping schedule? The Haakaa lets you collect extra colostrum without adding pump sessions during those already-overwhelming first days.
One caution: nipple stimulation before 37 weeks can trigger contractions. A Cochrane review confirmed breast stimulation can induce uterine activity. Always clear prenatal harvesting with your OB or midwife. After 37 weeks, risk is generally minimal for uncomplicated pregnancies.
Haakaa vs Elvie Curve vs Ladybug: Quick Comparison
Three passive collectors, three different jobs.
| Feature | Haakaa Original (150ml) | Haakaa Ladybug | Elvie Curve |
|---|---|---|---|
| Type | Suction milk collector | Wearable passive collector | Wearable passive collector |
| Capacity | 5 oz (150ml) | 2.5 oz (75ml) | 4 oz (120ml) |
| Wearable under clothes? | No — protrudes | Yes | Yes |
| Active suction? | Mild (squeeze-created) | No (catches leaking) | No (catches leaking) |
| Best for | Catching letdown, clogged duct soaks, stash building | All-day leak catching, discreet wear | Larger-capacity leak catching |
| Price range | $12–15 | $18–22 | $45–55 |
| Dishwasher safe? | Yes | Yes | Yes |
Haakaa Original collects the most per session thanks to active suction, but it sticks out and isn't wearable. Ladybug and Elvie Curve are for discreet all-day collection — the Curve holds more but costs 2–3x as much.
Start with the Haakaa Original for home sessions. Add a wearable for returning to work. For deeper comparisons, see our Elvie Stride review and best wearable breast pumps guide.
When Your Haakaa Keeps Falling Off (and Other Fixes)
The Haakaa falling off is the number one complaint. Almost always fixable.
Wet or oily skin. Lanolin, lotion, post-shower moisture — all seal killers. Pat completely dry. If you just applied nipple balm, wipe the areola with a dry cloth first.
Not enough air squeezed out. Compress the bulb harder than you think you need to. More air out = stronger suction.
Baby kicks it off.A rite of passage for every nursing pair. Hold the base while feeding, position baby's feet away from the Haakaa side, or tuck a receiving blanket around it. The Gen 3's wider base helps — slightly.
Flange not fully unfolded. Make sure the rim lies flat all the way around. Any folded-under section creates an air gap, and air gaps mean the Haakaa drops into your lap — taking 2 oz of milk with it. (Ask me how I know.)
Old silicone.After 6–8 months of daily use and boiling, silicone loses grip. If technique is solid but suction isn't, it's probably the Haakaa, not you. Replace it — at $12–15, it's cheaper than the milk you'll lose to one more spill.
Size mismatch.Haakaa makes one flange size. If you have a very large or very small areola, the fit may never feel secure. A bra-based collector like the Elvie Curve or Ladybug might work better since it doesn't rely on external suction.
