The Haakaa Ladybug is a passive milk collector that sits inside your bra and catches breast milk that would otherwise leak into a nursing pad. Unlike the original Haakaa pump, it doesn’t actively pull milk out. It simply collects what your body releases naturally during letdowns or between feeds. Here’s how to use it properly so you save every drop safely.
How to Apply the Ladybug
Start by pushing the small silicone plug into the outlet hole at the top of the Ladybug. This seals the collector so milk stays inside instead of leaking out the spout. Once the plug is secure, center the opening over your nipple and gently press down on the back of the dome-shaped body. Press it against your breast and release to create a light suction that holds it in place.
That suction is gentle and optional. It’s there to keep the Ladybug from shifting around, not to extract milk. Always wear the Ladybug inside a bra. Without one, it won’t stay put. A snug nursing bra works best because it keeps the collector flush against your breast and prevents tipping.
How It Differs From the Original Haakaa
If you’ve used the standard Haakaa silicone pump, you’ll notice the Ladybug feels quite different. The original Haakaa creates strong suction that actively draws milk out, functioning more like a manual pump. The Ladybug creates little to no active suction. It catches what would normally drip out during a letdown on the opposite breast, or what leaks between nursing sessions.
The tradeoff is comfort and convenience. The Ladybug is lower-profile, sits flat inside a bra, and can’t get kicked off by a squirmy baby. Many parents prefer it for nighttime feeds for exactly that reason: you can nurse on one side, collect from the other, and not worry about a pump toppling over in bed. During the day, when you’re more alert and can hold things in place, the original Haakaa may collect more milk because of its stronger suction. The Ladybug won’t dramatically increase your output, but it will capture milk you’d otherwise lose to a nursing pad.
Choosing the Right Size
The Ladybug comes in three capacities: 40 ml, 75 ml, and 150 ml (about 1.3 oz, 2.5 oz, and 5 oz). The right size depends on how much you typically leak. If you’re only catching light drips between feeds, the 40 ml version is compact and barely noticeable in your bra. If you have a strong letdown on the opposite side while nursing, the 75 ml or 150 ml gives you enough room to avoid overflow. A smaller collector is more discreet, but if it fills up and you don’t notice, you’ll end up with milk in your bra anyway.
How Long You Can Wear It
Haakaa recommends wearing the Ladybug for no longer than 4 hours at a time. Breast milk sitting against your warm skin for longer than that can become unsafe for your baby. If you want to wear it for a longer stretch, empty the collected milk into a bottle or storage bag every 2 to 3 hours and refrigerate or freeze it promptly.
This matters especially at night. If you put the Ladybug on before bed and sleep for 6 or 7 hours, the milk inside has been sitting at body temperature too long. That milk is not safe to feed to your baby. If you plan to use it overnight, set an alarm to empty it partway through, or accept that the overnight collection will need to be discarded. Any milk collected within the 4-hour window should follow standard breast milk storage guidelines: it can sit at room temperature for up to 4 hours after removal, go in the fridge for several days, or be frozen for longer storage.
Cleaning and Sterilizing
After each use, wash the Ladybug in hot, soapy water. Use a slightly rough sponge to gently scrub all surfaces, including the inside of the dome and around the plug and outlet. Rinse thoroughly. Though the silicone is dishwasher safe, hand washing is the recommended approach because it’s easier to inspect all the small parts for residue.
To sterilize, boil the Ladybug in water for 2 to 3 minutes. A steam sterilizer also works if you follow that device’s instructions. Two things to avoid: bleach-based cleaning products and UV sterilizers. Bleach can damage silicone, and UV light can shorten the product’s lifespan. Sterilizing tablets are also off the table for the same reason.
Tips for Getting the Most Out of It
The Ladybug works best when you wear it on the non-nursing side during a feed. Your letdown reflex triggers on both breasts simultaneously, so while your baby nurses on one side, the other side releases milk that the Ladybug catches passively. Over the course of a day, these small amounts add up. Some parents collect an extra ounce or two daily just from letdown they would have lost.
If the Ladybug keeps slipping or you’re not collecting much, check that your bra is snug enough to hold it in place. A loose bra lets the collector shift away from your nipple, and any gap means milk ends up on your skin instead of in the collector. You can also try applying it right before you start nursing on the other side, so it’s already in position when your letdown hits.
Between feeds, some people wear the Ladybug as a leak catcher throughout the day, replacing disposable nursing pads entirely. This works well in the early weeks when leaking is frequent. Just remember the 4-hour rule: empty it regularly and transfer the milk to proper storage if you want to save it.
