Introduction
You’re sitting on the sofa, your sweet baby finally latched and nursing contentedly on the left side. Suddenly, you feel that familiar, prickly tingle of a let-down. You look down and realize your right breast is leaking right through your nursing pad and onto your shirt. In that moment, many parents think the same thing: “I wish I could save every drop of that!”
Enter the silicone suction starter—most commonly known by the brand name Haakaa. It’s the darling of the breastfeeding world, often touted as a "must-have" for any new parent. It’s simple, cord-free, and seems to magically collect milk while you go about your business. But as you start seeing your milk stash grow, a common question arises: Does using a Haakaa actually increase your milk supply, or is it just catching what would have leaked anyway?
Understanding the nuances of how these devices affect your body is crucial. While breastfeeding is a natural process, it doesn’t always come naturally, and the tools we use can significantly impact our journey. In this post, we’re going to dive deep into the mechanics of milk production, explore whether a silicone collector can truly boost your supply, and discuss how to use it safely to avoid common pitfalls like oversupply or nipple discomfort. Our goal at Milky Mama is to empower you with the knowledge you need to navigate your breastfeeding journey with confidence, because we believe every drop counts—and your well-being matters too.
The Science of Milk Production: Supply and Demand
Before we can answer whether a silicone collector increases supply, we have to look at how our bodies actually make milk. We often say that breasts were literally created to feed human babies, but the "factory" inside them is highly responsive to external signals.
Milk production is primarily a system of supply and demand. When a baby latches or a pump is used, it sends a hormonal signal to your brain to release oxytocin and prolactin. Oxytocin triggers the "let-down reflex," causing the small muscles around the milk-making cells to contract and push milk into the ducts. Prolactin is the hormone responsible for telling your body to make more milk for the next time.
The most important rule to remember is: The more milk you remove, the more milk your body will make.
Your breasts have "receptors" that monitor how full or empty they are. When the breast is empty, the milk-making cells work at top speed. When the breast is full, a protein called Feedback Inhibitor of Lactation (FIL) builds up, signaling the body to slow down production. Because a silicone collector removes milk from the breast, it inherently interacts with this feedback loop.
How a Silicone Collector Works: Passive vs. Active
There is a lot of debate in the lactation community about whether a Haakaa-style device is a "pump" or a "collector." To understand the impact on your supply, we need to look at the physics of how it stays on your body.
A standard breast shell or ladybug-style collector sits inside your bra and catches leaks passively. There is no suction involved. However, the traditional Haakaa is a one-piece silicone vessel that you squeeze to create a vacuum before placing it on your breast.
That vacuum is the key. It isn't just "catching" milk; it is using constant, gentle suction to draw milk out of the ducts. Even though it doesn't have a motor or require you to manually pump a handle over and over, that suction is an external force removing milk that might have otherwise stayed in the breast.
Is it a pump?
Technically, yes. Because it uses a vacuum to extract milk, it functions as a silicone manual pump. This means that if you are using it frequently, you are technically "demanding" more milk from your body than your baby is drinking at that moment.
Does a Haakaa Increase Milk Supply?
The short answer is: Yes, it can.
For many parents, this is exactly what they want. If you are looking to slightly increase your production or build a modest freezer stash without the hassle of an electric pump, a silicone collector can be a wonderful tool. By removing that extra ounce or two during a nursing session, you are signaling to your body that your baby (or the "simulated" baby) needs more milk. Over a few days or weeks of consistent use, your body will likely respond by increasing its daily output.
However, because it is so easy to use, it is also easy to over-stimulate the breast. We often see parents who use the device at every single feeding, day and night. While it’s exciting to see those bags of "liquid gold" stacking up in the freezer, it’s important to monitor how your body is reacting.
The Power of the Let-down
When you nurse your baby on one side, the let-down reflex happens in both breasts simultaneously. This is why you leak on the opposite side. When you attach a suction device to the leaking side, you are taking advantage of that natural hormonal surge to remove milk with very little effort.
If you find yourself needing a boost but want to stick to natural support, we often recommend pairing your efforts with nourishing options. For example, enjoying our Emergency Brownies or a refreshing glass of Pumpin Punch™ can provide the nutritional support your body needs while you are increasing demand.
The Risks of Using a Silicone Collector Too Frequently
While we love tools that make life easier, "more" isn't always "better" when it comes to milk supply. Using a silicone pump too often can lead to a few challenges that we see frequently in our virtual lactation consultations.
1. Developing an Oversupply
Oversupply sounds like a "good" problem to have, but it can be quite taxing on both you and your baby. When your body makes significantly more milk than your baby needs, you may experience:
- Constant breast engorgement and discomfort.
- Frequent clogged ducts.
- An increased risk of mastitis.
- A forceful let-down that makes baby gag, choke, or pull off the breast.
If you notice that you are constantly feeling "full" even after nursing, or if your baby is struggling to manage the flow, it might be time to scale back on the suction.
2. The Foremilk/Hindmilk Imbalance
Milk changes composition during a feeding. The milk at the beginning (foremilk) is typically higher in lactose and thinner, while the milk toward the end (hindmilk) is higher in fat. Because a silicone collector often only catches the first part of the let-down, the milk collected is often very high in lactose.
If a baby is fed large amounts of this "collector milk" via bottle, or if they are getting mostly foremilk because the "extra" was removed before they switched sides, it can lead to green, frothy stools and gassiness.
3. Nipple Sensitivity and Vasospasms
The suction on a silicone pump is constant. Unlike an electric pump that has a rhythmic "suck-release" cycle, or a baby who pauses to swallow and breathe, the Haakaa pulls continuously. For some parents, this constant tension can cause nipple pain or even vasospasms (where the blood flow is restricted, causing the nipple to turn white and feel painful).
4. Impact on Baby's Weight Gain
In some cases, if the collector is used on the "second" side before the baby gets a chance to nurse there, it can remove the easiest-to-access milk. If your baby is a "sleepy" eater, they may get frustrated by the slower flow that remains and fall asleep before they’ve had a full meal. This is a scenario we watch closely, as it can occasionally lead to slower weight gain if not managed correctly.
Practical Scenarios: When to Use (and When to Pause)
To help you decide how a silicone collector fits into your life, let’s look at a couple of real-world scenarios.
Scenario A: The "Just in Case" Stash Maya is returning to work in two months. She doesn’t want to spend hours hooked up to an electric pump right now, but she wants to have a small stash of milk for her baby’s first week at daycare.
- The Strategy: Maya uses her silicone collector during her first morning feed only. This is when milk supply is naturally at its highest. She collects about 2 ounces, which she freezes. By doing this only once a day, she builds her stash slowly without causing a massive oversupply.
Scenario B: Relieving Engorgement Sarah’s baby has started sleeping a longer stretch at night. Sarah wakes up at 4 AM feeling extremely full and uncomfortable, but her baby is still fast asleep.
- The Strategy: Instead of doing a full pumping session, Sarah attaches the silicone collector with light suction just to take the "pressure" off. She removes just enough milk to feel comfortable, which helps her get back to sleep without telling her body to produce a massive surplus at that hour.
Scenario C: Managing a Forceful Let-down Tasha has a very strong let-down, and her baby often coughs and sputters when the milk first starts flowing.
- The Strategy: Tasha uses the silicone collector for just 1-2 minutes before she latches her baby. This catches the most forceful part of the flow, making it easier for her baby to latch and swallow comfortably once the "firehose" effect has calmed down.
Tips for Using Your Silicone Collector Safely
If you’ve decided that a silicone pump is right for your journey, here are our top tips for using it effectively:
- Watch the Suction: You don't need to fold the flange back and squeeze the base to the max every time. Sometimes a gentle squeeze is all you need to stay attached. If it hurts, break the seal and try again with less suction.
- Limit the Frequency: If you aren't trying to aggressively increase supply, try using it just 1-3 times per day rather than at every feed.
- Alternate Sides: If your baby usually eats from both sides, be careful about using the collector on the second side. You might want to let the baby finish the first side, start them on the second side, and then use the collector on the first side to catch any remaining milk.
- Stay Hydrated: Whenever you are removing extra milk, you need to replenish your fluids. Our Milky Melon™ or Lactation LeMOOnade™ are excellent ways to stay hydrated while supporting your lactation goals.
- Check Your Baby's Cues: Always prioritize the baby at the breast. If your baby seems fussy, hungry, or isn't gaining weight as expected, it’s a good idea to put the collector away for a few days and focus on direct nursing.
Supporting Your Supply Naturally
Whether you use a silicone collector or not, supporting your body’s ability to produce milk is a holistic process. At Milky Mama, we believe in a "whole-body" approach to breastfeeding.
Nutrition and Supplements
Your body works hard to create milk. Providing it with the right herbs and nutrients can make a world of difference. Many of our "Milky Mamas" find that adding a supplement like Lady Leche™ or Pumping Queen™ helps them maintain a consistent supply, even during stressful times or growth spurts.
If you’re specifically looking to enrich the quality of your milk or support flow, Dairy Duchess™ and Pump Hero™ are fan favorites designed with specific lactation goals in mind.
Note: These products are not intended to diagnose, treat, cure, or prevent any disease. Always consult with your healthcare provider or a lactation professional before starting new supplements.
Emotional Support and Community
Breastfeeding can feel lonely, especially at 3 AM. But you aren't alone! Joining a community like The Official Milky Mama Lactation Support Group on Facebook can give you a place to ask questions, share your wins, and get advice from others who have been exactly where you are.
We also encourage you to follow us on Instagram for daily tips, encouragement, and a reminder that you are doing an amazing job.
When to Call in a Professional
If you are struggling with supply—whether it’s too much or too little—please don't hesitate to reach out for help. Breastfeeding is a learned skill for both you and your baby. If you experience persistent pain, frequent clogs, or concerns about your baby’s growth, a virtual lactation consultation can provide personalized, evidence-based guidance.
Our IBCLCs can help you troubleshoot your use of the Haakaa, check your baby's latch, and create a custom plan that fits your family's needs. If you’re just starting out and want to build a strong foundation, our Breastfeeding 101 class is a great place to start.
Storing Your Collected Milk
If you are successfully using a silicone collector to build a stash, you’ll want to make sure you’re storing that "liquid gold" properly.
- Cool Before Combining: If you collect milk at 10 AM and again at 2 PM, make sure the fresh milk is cooled in the fridge before adding it to the older milk.
- Label Everything: Use the "first in, first out" rule. Always label your storage bags with the date and the number of ounces.
- Small Portions: Store milk in 2-4 ounce increments. This prevents waste, as you can always thaw more, but you can't re-freeze milk once the baby has started drinking from the bottle.
- Know the Guidelines: Generally, freshly expressed milk can stay at room temperature for about 4 hours, in the fridge for 4 days, and in the freezer for 6-12 months.

Inclusion and Representation in Breastfeeding
At Milky Mama, we believe that representation matters. Historically, Black breastfeeding moms have faced unique barriers to support and lower rates of breastfeeding due to systemic issues and a lack of culturally competent care.
We are proud to be a Black-owned business that centers the needs of all breastfeeding families. Whether you are nursing, pumping, using a silicone collector, or doing a combination of everything, you deserve to see yourself reflected in the education you receive. We are here to provide a safe, non-judgmental space for every parent, regardless of their background or feeding choices. Remember, your journey is unique, and you are the best expert on your baby.
The Bottom Line
Does a Haakaa increase milk supply? It certainly can, thanks to the principle of supply and demand. By removing extra milk via gentle vacuum suction, you are sending a signal to your body to keep the "factory" running at a higher capacity.
However, like any tool, it works best when used with intention. If you want a slight boost or a small freezer stash, it’s a game-changer. If you find yourself heading toward oversupply or experiencing discomfort, it’s okay to scale back.
Breastfeeding is a marathon, not a sprint. It’s about finding the rhythm that works for you and your little one. Whether you’re using a silicone pump, enjoying our Oatmeal Chocolate Chip Cookies, or just taking it one feed at a time, know that you are doing something incredible for your baby.
Every drop counts, but your peace of mind counts just as much.
FAQ
1. Can I use a silicone collector if I don't leak on the other side?
Yes! Many parents who don't naturally leak still find that the gentle suction of a silicone pump helps them express milk during a let-down. While it may not collect as much as someone with a very active leak, it can still be an effective way to gather an extra half-ounce or ounce during a feed.
2. Is it okay to use the Haakaa at every feeding?
While you can, it may lead to an oversupply for many people. If you start to feel constantly engorged or notice your baby is struggling with a very fast flow, try reducing use to just a few times a day. Every body is different, so monitor your own comfort and your baby's reaction.
3. Does the milk from a silicone collector have enough fat?
The milk collected is often "foremilk," which is thinner and higher in lactose. However, if you are also nursing your baby directly, they are getting the high-fat hindmilk from the breast they are latched onto. If you are worried, you can gently massage your breast while using the collector to help move the fat globules forward, or mix the collected milk with milk from a full pumping session.
4. Can using a silicone pump cause clogged ducts?
In some cases, yes. If the suction isn't strong enough to fully empty certain ducts, or if it creates an oversupply that your baby can't keep up with, milk can back up and cause a clog. If you feel a lump or a sore spot, stop using the suction and focus on heat, gentle massage, and having the baby nurse on that side.
