Introduction

If you have spent any time in breastfeeding circles or on social media, you have likely seen the simple, silicone device known as the Haakaa. It is often praised for its ability to catch "liquid gold" that would otherwise be lost in a nursing pad. Many new parents wonder if this handy tool is just for catching leaks or if it can do more. A common question we hear is whether using a Haakaa will actually increase your milk supply.

At Milky Mama, we know that understanding your body and your tools is the first step toward a confident breastfeeding journey. If you want hands-on help while you sort through your feeding goals, our Breastfeeding Help and Virtual Consultations page is a good place to start. This post will explore how the Haakaa works, its impact on your milk production, and how to use it safely. We will also discuss the differences between passive collection and active pumping. Our goal is to help you navigate your lactation goals with clarity and ease.

Understanding the relationship between milk removal and milk production is essential for every breastfeeding parent. While the Haakaa is a simple tool, it can have a significant impact on your lactation journey.

How the Haakaa Works

The Haakaa is a one-piece silicone breast pump that uses suction to draw milk from the breast. Unlike an electric pump, it does not have a motor or moving parts. Unlike a traditional manual pump, it does not require you to repeatedly squeeze a handle to maintain suction. Instead, it uses a continuous vacuum to encourage milk flow.

When you apply the Haakaa to your breast, you squeeze the base to create a vacuum. When you release the base, the device stays attached to your breast and pulls gently on the nipple and areola. This suction is often enough to trigger or take advantage of the let-down reflex.

The let-down reflex, or the milk ejection reflex, is a hormonal response. When your baby latches or when you begin pumping, your brain releases oxytocin. This hormone causes the small muscles around the milk-producing cells in your breasts to contract. This contraction pushes the milk into the ducts and toward the nipple.

For many parents, the let-down reflex happens in both breasts at the same time. If you are nursing on the left side, your right side will likely let down as well. The Haakaa is designed to be placed on the non-nursing side to catch the milk that is released during this time.

The Connection Between Milk Removal and Supply

To answer whether the Haakaa will increase your supply, we must first look at the "supply and demand" principle. This is the golden rule of lactation. Your breasts are not just storage tanks; they are milk-producing factories. Your body creates milk based on how much milk is removed.

When milk is removed from the breast, whether by a baby, an electric pump, or a Haakaa, it signals your body to make more. If the breast is kept empty, the factory stays busy. If the breast remains full, a protein called Feedback Inhibitor of Lactation (FIL) builds up. This protein tells your body to slow down production.

Because the Haakaa uses suction to remove milk, it is more than just a passive "drip catcher." A simple shell or cup that sits in your bra catches leaks without suction. The Haakaa, however, actively draws milk out. This removal of milk tells your body that there is a demand for that extra volume.

If you use the Haakaa consistently at every feeding, your body will likely respond by increasing its overall output. For many parents, this is a helpful way to build a freezer stash without the time commitment of a full pumping session. However, it is important to be intentional about how often you use it.

Will the Haakaa Increase Supply for Everyone?

While the Haakaa can increase supply, the results vary from person to person. Every body is different, and several factors influence how you might respond to this type of suction.

Some parents have a very sensitive let-down reflex. They may find that the Haakaa fills up quickly and significantly boosts their supply. Other parents may find that they only get a few drops. This does not necessarily mean they have a low supply; it simply means their body responds differently to the gentle, continuous suction of the silicone pump.

The Haakaa is generally not considered an effective tool for a parent dealing with a significant low milk supply. In those cases, active stimulation from a baby's latch or a hospital-grade electric pump is usually required. For a deeper comparison of output and stimulation, you may find our post on Pumping vs. Breastfeeding output differences helpful. The Haakaa is a supportive tool, but it does not provide the same rhythmic stimulation as an active pump or a nursing infant.

If you are looking for a boost in your supply, we often recommend looking at your overall routine. This includes frequent nursing, staying hydrated with drinks like our Pumpin' Punch lactation drink mix, and ensuring you are getting adequate nutrition. The Haakaa can be a part of that routine, but it is rarely the only solution for increasing supply.

The Risk of Oversupply

Because the Haakaa is so easy to use, it is easy to overdo it. If you use the silicone pump at every single feeding session, you are effectively telling your body you are feeding more than one baby. This can lead to a condition known as oversupply.

Oversupply might sound like a "good problem" to have, but it can be quite challenging. For the parent, oversupply often leads to frequent engorgement. Engorgement occurs when the breasts become painfully full and hard. This can increase the risk of blocked milk ducts and mastitis, which is a painful inflammation of the breast tissue.

For the baby, an oversupply can lead to a very fast let-down. If the milk is spraying or flowing too quickly, the baby may gag, choke, or pull off the breast during feeds. This can make feeding sessions stressful for both of you.

Key Takeaway: The Haakaa is a powerful tool. Using it too frequently can signal your body to produce more milk than your baby needs, potentially leading to oversupply and discomfort.

Foremilk and Hindmilk Balance

Another consideration when using the Haakaa to increase supply is the balance of milk types. Breast milk changes during a feeding session.

Foremilk: This is the milk available at the start of a feed. It is usually thinner and higher in lactose (milk sugar).
Hindmilk: This is the milk that comes later in the feed as the breast is drained. It is higher in fat and calories.

The Haakaa primarily collects the foremilk that is released during the initial let-down. If you are using the Haakaa to collect milk and then feeding that milk to your baby later, it may be lower in fat than milk removed by a baby or an electric pump.

If a baby receives a large volume of foremilk and not enough hindmilk, they may experience "foremilk/hindmilk imbalance." This can cause the baby to have green, frothy stools and become gassy or fussy. If you collect milk with a Haakaa throughout the day, we recommend pooling the milk together. This helps ensure a better balance of fat and nutrients in the final bottles.

How to Use a Haakaa to Support Your Supply Safely

If you want to use the Haakaa to gently support your supply or build a small stash, it is best to have a plan. You do not have to use it at every feed to see results.

Limit Your Sessions

Start by using the Haakaa once or twice a day. Many parents find the most success during the first feed of the morning. Milk supply is often highest in the early hours of the day. Using it once in the morning can help you collect a few ounces for your stash without triggering a massive oversupply.

Monitor Your Body

Pay attention to how your breasts feel. If you start feeling constantly engorged or start developing "clogs" (tender lumps in the breast), you may need to scale back. For more in-depth reading on those symptoms, our guide to clogged ducts and mastitis can help. Your body should feel comfortable. Breastfeeding is a natural process, but it should not be a painful one.

Adjust the Suction

You can control how much milk the Haakaa draws out by how much you squeeze it. For a gentle "catch" of leaking milk, use a light squeeze. For more active removal to increase supply, you can use a firmer squeeze or even "fold back" the flange before applying it to get a stronger vacuum.

Action List for Haakaa Success:

Choose 1-2 specific feeds a day to use the device.
Check your nipple position to ensure it is centered and not rubbing.
Clean and sterilize the device according to the manufacturer's instructions.
Combine your collected milk with milk from other sessions to balance fat content.

When the Haakaa Is Not Enough

While the Haakaa can help some parents, it is not a replacement for professional support or higher-level tools if you are struggling. If you are concerned that your baby is not getting enough milk, or if you are experiencing pain, please reach out to a professional.

At Milky Mama, we offer virtual lactation consultations. A certified lactation consultant can look at your specific situation. They can help you determine if your supply is truly low or if you just need a few adjustments to your routine. Sometimes, small changes in position or latch can make a huge difference.

If you are using the Haakaa because you are worried about your supply, remember that you are doing an amazing job. Stress can actually impact your let-down reflex. Taking a moment to breathe, hydrate, and enjoy a nourishing treat can do wonders for your well-being and your milk flow.

Managing Nipple Comfort

Because the Haakaa uses continuous suction, some parents find it can be hard on their nipples. Unlike a baby or an electric pump, there is no "rest" phase in the suction. It is a constant pull.

If you experience nipple pain, try reducing the suction. You can do this by squeezing the base less firmly. You should also ensure your nipple is not touching the sides of the "neck" of the device. If the nipple is rubbing, it can cause skin irritation or even vasospasms. A vasospasm is when the blood vessels in the nipple constrict, often causing the nipple to turn white and feel very painful.

If you have sensitive skin, you might prefer using a different type of collector. Some collectors sit inside the bra and use very little suction. These are often better for those who only want to catch true leaks without stimulating the breast for more milk.

Building a Stash Without the Stress

Many parents want to increase their supply because they are worried about returning to work or being away from their baby. The Haakaa is a popular way to build a "passive" stash. This means you are collecting milk while doing something you were already doing—feeding your baby.

However, you do not need hundreds of ounces in your freezer to be successful. Most babies only need enough milk for the hours you are away. If you can collect an ounce or two a day with your Haakaa, that adds up over time.

If you find that the Haakaa is not giving you the volume you need, you might consider adding a gentle herbal supplement. Our Lady Leche lactation supplement and Pumping Queen herbal supplement are designed to support milk production as part of a broader routine. We believe in providing support that feels empowering and fits into your lifestyle.

Common Misconceptions

There are a few myths about the Haakaa and milk supply that we should clear up.

Myth 1: It only catches what would have leaked anyway. As we discussed, the suction means it is removing more milk than a simple leak. This is why it can lead to an increase in supply.

Myth 2: It is as effective as an electric pump. For most people, it is not. An electric pump uses a rhythmic cycle that mimics a baby’s nursing. This is much more effective at stimulating the hormones needed for long-term milk production.

Myth 3: You have to use it at every feed. Absolutely not. In fact, for many, using it at every feed is a recipe for oversupply and discomfort.

Myth 4: It works for every person. Some parents find they get almost nothing with a Haakaa, even with a great supply. This is often just a matter of how their tissue reacts to a vacuum versus a rhythmic pump.

The Importance of Professional Guidance

If you are trying to change your milk supply, it is always a good idea to talk to a professional. Whether you want to increase it or manage an oversupply, an International Board Certified Lactation Consultant (IBCLC) is your best resource.

Our founder, Krystal Duhaney, is an RN, BSN, and IBCLC. Everything we do at Milky Mama is rooted in clinical expertise. If you want guided education beyond one-on-one support, our online courses can also be a helpful next step. If you find that the Haakaa is causing issues like mastitis or if your baby is struggling with a fast flow, don't hesitate to seek help.

Signs Your Supply is Increasing

As you use the Haakaa, how will you know if your supply is actually going up? Here are a few signs:

You get more milk in the Haakaa over time. If you started with half an ounce and are now getting two ounces, your body has responded to the demand.
Your breasts feel fuller. You may notice more fullness between feeds.
More frequent leaking. You might find you are leaking on the "off" side even when you aren't using the collector.
Changes in baby's behavior. Your baby might seem satisfied sooner, or they might struggle with a faster flow.

If you see these signs and you are happy with the results, you can continue your routine. If it becomes "too much," simply reduce the number of times you use the device each day.

Using the Haakaa for Engorgement

Sometimes the goal isn't just to increase supply, but to find relief. In the early days when your milk first "comes in," your breasts can feel very heavy and painful. This is engorgement.

Using the Haakaa for a few minutes before a feed can help soften the breast. This makes it easier for your baby to get a good latch. When the breast is too hard, the nipple can become flat, making it difficult for the baby to take enough tissue into their mouth.

Be careful not to over-drain the breast during these times, as you don't want to tell your body to make even more milk. Use it just enough to feel comfortable.

Key Takeaway: The Haakaa is a versatile tool for relief, but use it sparingly during engorgement to avoid signaling your body to produce an even larger volume of milk.

Final Thoughts on Supply Management

Managing your milk supply is a balancing act. It is about meeting your baby's needs while keeping yourself comfortable and healthy. The Haakaa can be a wonderful part of that balance when used mindfully.

If you decide to use a Haakaa to increase your supply, remember to be patient with your body. It can take a few days of consistent demand for your supply to shift. While you wait, focus on your wellness. Drink plenty of water, eat nourishing meals, and remember that every drop you collect is a testament to your hard work.

If you like having ready-to-go options on busy days, our lactation snacks collection is a simple way to keep support close at hand. We are here to support you every step of the way. Whether you are using a Haakaa, an electric pump, or nursing exclusively, your journey is unique and valid.

Conclusion

The Haakaa can indeed increase milk supply for many parents because it uses suction to remove milk, thereby signaling the body to produce more. However, it is important to use it with intention to avoid the risks of oversupply and nipple discomfort. By limiting its use and monitoring your body's cues, you can successfully build a stash or boost your output.

The Haakaa uses passive suction to remove milk, which can increase supply.
Using it too often can lead to oversupply, engorgement, and mastitis.
It is most effective when used once or twice a day, especially in the morning.
Balanced nutrition and hydration are key partners to using any lactation tool.

FAQ

Does the Haakaa work for everyone to increase supply?

No, the Haakaa does not work for everyone. Some parents find that their let-down reflex does not respond well to the continuous, gentle suction of a silicone pump. While it is a great tool for many, it is not a guaranteed way to increase milk production for every body.

Can using the Haakaa cause mastitis?

Yes, if used excessively, the Haakaa can lead to oversupply, which increases the risk of mastitis. When the breasts are constantly overstimulated to produce more milk than needed, it can lead to milk stasis or blocked ducts. For extra help when you are dealing with these issues, revisit our Breastfeeding Help and Virtual Consultations page. Always monitor your breast health and scale back if you feel frequent lumps or pain.

Should I use the Haakaa at every feeding session?

Generally, we do not recommend using the Haakaa at every feeding session unless you are specifically directed to do so by a lactation consultant. For most parents, using it once or twice a day is enough to build a stash without causing an uncomfortable oversupply. Overusing it can make your body think it needs to produce milk for multiple babies.
