Introduction

If you have spent any time in breastfeeding circles or scrolled through parenting social media lately, you have likely seen the simple, one-piece silicone device known as the Haakaa. It is often called a "passive pump" or a "milk collector." For many nursing parents, this tool feels like a bit of magic. It catches the milk that would otherwise leak into a nursing pad while you feed your baby on the opposite side.

Because it is so easy to use, many parents wonder about its impact on their overall production. A common question we hear at Milky Mama is: will Haakaa increase milk supply? The short answer is that it can, but it depends entirely on how you use it. Understanding the way this tool interacts with your body is essential for meeting your feeding goals without accidentally creating new challenges.

This post will cover the science of how silicone pumps work, the potential for increasing supply, and how to use one safely. We want to help you feel empowered and knowledgeable as you navigate your lactation journey. Our goal is to ensure that every drop counts while keeping your well-being a top priority.

How a Silicone Pump Works

To understand if a Haakaa will increase milk supply, we first need to look at how it functions. Unlike a traditional manual pump that requires constant rhythmic squeezing or an electric pump that uses a motor, the Haakaa uses continuous suction. When you squeeze the base and apply it to your breast, it creates a vacuum.

This vacuum does more than just hold the device in place. It gently pulls on the nipple and areola. When your baby starts nursing on the other side, your body triggers the let-down reflex. This is a hormonal response where oxytocin causes the tiny muscles in your breasts to contract and push milk into the ducts.

While the let-down reflex happens in both breasts simultaneously, the Haakaa uses that suction to draw the milk out of the non-nursing side. It is often described as "passive," but because there is active suction involved, it is more of a gentle pump than a simple collection cup. This distinction is important because any time you remove milk from the breast, you are sending a message to your body.

Will Haakaa Increase Milk Supply?

For many parents, using a Haakaa can indeed increase milk supply. This happens because of the fundamental rule of lactation: supply and demand. Your body is constantly calibrating how much milk to make based on how much is being removed. If you use a silicone pump at every feeding, your body perceives a higher demand than what your baby is actually drinking.

When you remove extra milk during a session, your breasts are emptied more thoroughly. Empty breasts work faster to produce more milk. Over time, your body may adjust to this "extra" demand by increasing its daily output. For a parent who is worried about a slight dip in supply, this can be a helpful, low-stress way to provide extra stimulation.

However, it is important to remember that this increase is not guaranteed for everyone. Some parents find that the gentle suction of a silicone pump is only enough to catch the initial let-down and does not significantly change their overall production. Others may find that their bodies are very sensitive to the extra stimulation and see a noticeable jump in supply within a few days of consistent use.

Key Takeaway: Because a Haakaa removes milk through suction, it provides extra stimulation that can signal your body to produce more milk over time.

Understanding the Supply and Demand Principle

Breast milk production is a complex biological process, but it follows a relatively simple economic model. When a baby nurses or a pump is used, the stimulation sends signals to the brain to release prolactin and oxytocin. Prolactin is the hormone responsible for making the milk, while oxytocin handles the delivery.

If the "demand" (milk removal) is high, the "supply" (milk production) usually follows suit. By using a Haakaa while nursing, you are essentially telling your body that you have a very hungry baby—or even two babies. If you consistently remove 1 or 2 ounces of extra milk during each feed, your body will try to keep up with that 10 to 15-ounce daily "bonus" demand.

This is why we often suggest being intentional with how often you use the device. If you are happy with your current supply and simply want to catch a few leaks, you might not need to use the suction feature at full strength. If you are looking for a boost, using it more frequently may help support your goals.

Potential Risks of Using a Haakaa Too Often

While an increase in supply sounds like a dream for many, there is such a thing as having too much milk. This condition is known as oversupply or hyperlactation. If you use a silicone pump too aggressively, you may accidentally tip the scales.

The Risk of Oversupply

Oversupply can lead to several uncomfortable issues for both you and your baby. When the breasts are constantly overfilled, you are at a higher risk for clogged ducts and mastitis. Mastitis is an inflammation of the breast tissue that can sometimes lead to infection. It is often painful and can make you feel very ill.

For the baby, an oversupply often means a very fast let-down. If the milk is spraying or flowing too quickly, the baby may gulp, gag, or pull off the breast in frustration. This can lead to the baby swallowing excess air, resulting in a gassy, fussy infant.

The Foremilk and Hindmilk Balance

There is also a concern regarding the composition of the milk removed by a Haakaa. Foremilk is the milk available at the start of a feed; it is generally higher in lactose and lower in fat. Hindmilk comes later in the feed and is creamier and higher in fat.

Because a silicone pump often only catches the first part of the let-down, the milk collected may be primarily foremilk. If you use the Haakaa to remove a large amount of milk before the baby switches sides, the baby might miss out on some of that easy-to-access, high-fat milk. If a baby gets too much foremilk and not enough hindmilk, they might experience "lactose overload," which can cause green, frothy stools and general discomfort.

Nipple Sensitivity and Pain

Leaving a silicone pump on with high suction for the entire duration of a feed can also cause nipple soreness or vasospasms. A vasospasm happens when the blood vessels in the nipple constrict, often causing a sharp, burning pain and the nipple turning white or purple. If you feel any pain while using the device, it is important to break the suction and readjust.

Using a Haakaa to Build a Milk Stash

One of the most popular ways to use a silicone pump is to build a "freezer stash" without the need for a separate, intense pumping session. This is a fantastic middle ground for parents who want to have extra milk on hand for an occasional bottle or for returning to work.

To use the Haakaa as a stash builder without causing a massive oversupply, many lactation professionals recommend limiting its use to once or twice a day. The morning is often the best time, as milk volume is typically highest after a night of rest. By catching the let-down during just your first one or two feeds of the day, you can slowly accumulate a few ounces at a time.

If you find that you are collecting more milk than you need, you can simply reduce the frequency. This allows you to stay in control of your production. At Milky Mama, we believe that every drop counts, and building a stash should feel like a relief, not another chore on your to-do list.

How to Use Your Silicone Pump Correctly

To get the best results and ensure you are supporting your supply safely, following a proper technique is key.

  1. Sterilize before first use: Always start with a clean device. Follow the manufacturer's instructions for boiling or steaming.
  2. Fold back the flange: Many people find that folding the wide "petals" of the pump back makes it easier to center on the nipple.
  3. Squeeze the base: The more you squeeze the bottom of the pump, the stronger the suction will be. Start with a gentle squeeze.
  4. Center and release: Place the opening over your nipple, ensuring it is centered so there is no rubbing or pinching. Unfold the flange onto your breast and release the squeeze.
  5. Check the flow: You should see milk begin to drip or spray into the container once your let-down occurs.
  6. Adjust as needed: If the suction feels too strong, squeeze the base slightly to let a little air in, or remove it and start over with a lighter squeeze.

Next Steps for Success:

  • Start by using the pump once a day to see how your body responds.
  • Monitor your baby's behavior to ensure they aren't frustrated by changes in flow.
  • Keep an eye out for signs of oversupply, like constant engorgement or frequent clogs.
  • Store your collected milk in small increments (2–4 ounces) to prevent waste.

When to Consult a Professional

While silicone pumps are generally safe and easy to use, they are not a replacement for clinical support if you are experiencing significant supply issues. If you are worried about a low milk supply, a Haakaa may not provide enough stimulation on its own to solve the problem. In those cases, working with a lactation consultant is the best path forward.

A professional can help you evaluate your baby's latch and ensure that milk is being transferred effectively. They can also help you determine if herbal support might be right for you. For many parents, supplements like our Lady Leche or Pumping Queen can offer the targeted support needed to maintain a healthy supply. These products are formulated by Krystal Duhaney, an IBCLC who understands the delicate balance of lactation.

If you find that you have developed a painful lump that won't go away, or if you have a fever and flu-like symptoms, please reach out to your healthcare provider. These can be signs of mastitis, which requires professional attention.

When you need personalized help with latch, pumping, or supply concerns, you can book a breastfeeding consultation for individualized guidance.

Dietary Support for Your Supply

While tools like the Haakaa provide physical stimulation, your body also needs the right nutrients to produce milk. Hydration is the most important factor. Drinking plenty of water and including electrolyte-rich drinks can make a world of difference. Our Lactation LeMOOnade or Pumpin Punch are great options for staying hydrated while supporting your supply with lactation-friendly ingredients.

In addition to hydration, consuming specific foods known as galactagogues can be helpful. These are substances that may help support milk production. Oats, brewer's yeast, and flaxseed are classic examples. If you are looking for a tasty way to include these in your diet, our Emergency Lactation Brownies are a favorite among our community. They are designed to be a convenient, delicious treat that fits perfectly into a busy parent's schedule.

Remember, no tool or supplement is a magic wand. They work best when combined with frequent milk removal and a healthy, supportive environment. You are doing a hard job, and it is okay to use the tools available to make it a little easier.

Action Plan: Balancing Supply and Collection

If you want to use a Haakaa without causing issues, follow this simple strategy:

  • Week 1: Use the collector once a day during the morning feed. Focus on getting a comfortable fit.
  • Observe: Watch for any changes. Are you feeling more engorged? Is the baby satisfied?
  • Adjust: If you feel you need more milk, increase to two sessions a day. If you feel too full, back off to every other day.
  • Support: Pair your efforts with nourishing snacks and plenty of fluids to keep your body fueled.

"Your breastfeeding journey is unique. Whether you collect half an ounce or five ounces, your effort is what matters most for your baby."

Conclusion

The question of whether a Haakaa will increase milk supply depends on your individual body and how frequently you use the device. Because it uses suction to remove milk, it does act as a gentle stimulator of the supply-and-demand system. For many, it is a wonderful tool to build a small stash or provide a slight boost in production. However, using it too often can lead to oversupply and other complications, so it is best used with intention and care.

  • Silicone pumps use suction, which can stimulate extra milk production.
  • Using the device too frequently may lead to oversupply or foremilk/hindmilk imbalances.
  • For most parents, using it once or twice a day is a safe way to build a freezer stash.
  • Always prioritize your comfort and your baby's feeding needs over the amount of milk collected.

FAQ

Does the Haakaa work if I don't leak on the other side?

Yes, many parents who do not experience leaking still find success with a silicone pump because it uses suction to draw milk out. While leaking is a sign of a strong let-down, the vacuum created by the device can often trigger milk flow even in those who typically stay dry on the non-nursing side.

Can I use a Haakaa instead of an electric pump?

It depends on your goals; a Haakaa is excellent for catching extra milk or relieving mild engorgement, but it usually cannot replace an electric pump for someone who is exclusively pumping or needs to maintain a full supply while away from their baby. Electric pumps provide the rhythmic, multi-phase stimulation needed to fully empty the breasts and maintain long-term production.

How much milk should I expect to get with a Haakaa?

Output varies significantly from person to person, with some parents collecting only a few drops while others may get 2 to 4 ounces per session. Most people find they collect the most milk during the first morning feed, and it is normal for the amount to decrease as the day goes on and your supply naturally dips.

Will using the Haakaa take milk away from my baby?

If your baby is nursing on one side and you are using the Haakaa on the other, your baby will still get plenty of milk when you switch them to the second side because breasts are constantly producing milk. However, if you have a lower supply or your baby is struggling to gain weight, you should consult an IBCLC before using a collector to ensure the baby is getting the high-fat milk they need first.
