Figuring out how to use your breast pump can feel like learning a new gadget. The suction settings, the modes, the speeds—it’s a lot! But here’s the good news: understanding how pumping suction works can make the whole process smoother and more comfortable. Plus, it can help you get the most out of each session.
How is Breast Pump Suction Measured?
Breast pump suction is measured in millimeters of mercury (mmHg), a unit that represents the level of vacuum pressure the pump generates. Most breast pumps offer a range of suction levels, allowing users to adjust the intensity based on comfort and efficiency. For example, personal pumps typically provide suction levels between 200-300 mmHg, while hospital-grade pumps can go up to 300-350 mmHg. This variability ensures that users can tailor the suction to suit their individual needs and comfort preferences.
Does Higher Suction Mean More Milk or Increased Milk Flow?
Contrary to popular belief, higher suction does not necessarily equate to more milk or faster milk flow. Using suction that is too high can compress breast tissue and milk ducts, which may actually reduce milk flow by restricting the passage of milk. Excessive suction can also cause discomfort or pain, leading to a less effective pumping session.
Studies have shown that pumping at the Maximum Comfort Vacuum (MCV)—the highest suction level that remains comfortable—optimizes milk flow and milk volume. The key is finding a balance where suction stimulates milk ejection without causing discomfort. Comfort over maximum suction is essential for effective pumping.
What Is the Best Breastfeeding Suction Level for You?
The best pumping suction level is the one that aligns with your Maximum Comfort Vacuum (MCV). This level varies between individuals and can even change day-to-day or between pumping sessions. To find your MCV:
- Start with the pump at its lowest suction setting.
- Gradually increase the suction until it feels slightly uncomfortable.
- Lower the suction slightly to where it feels comfortable but effective.
A well-chosen suction level will stimulate milk ejection reflexes and maintain milk flow without causing pain or tissue compression.
What Are All of the Settings for a Breast Pump?
Breast pumps typically offer two adjustable settings: suction strength and speed. These settings are designed to mimic a baby’s natural nursing patterns, which consist of two main phases:
- Stimulation Phase (or Massage Mode). A baby begins feeding with quick, shallow sucks to stimulate milk flow. Breast pumps replicate this with high-speed, low-suction settings. On the Momcozy M9, stimulation mode is the default when the pump is turned on, starting with low suction for comfort.
- Expression Phase. Once milk begins to flow, a baby transitions to slower, deeper sucks for efficient milk extraction. This is mirrored in pumps by lower speed and higher suction settings. The Momcozy M9 allows for precise adjustments in this mode, offering 15 suction levels to suit individual needs.
- Mixed Mode (if available). Combines stimulation and expression phases for efficient milk extraction and comfort.
Advanced pumps like the Momcozy M9 also provide app-controlled customization, allowing users to personalize their experience. This includes adjusting modes and suction levels via the Momcozy App for optimal efficiency and comfort.
What Is the Best Breast Pump Setting for Letdown?
The letdown phase, also known as the stimulation phase, is crucial for triggering milk flow. To achieve letdown, you should use high-speed, low-suction settings. These settings mimic a baby’s quick, shallow sucking when they first latch on, which naturally stimulates the milk ejection reflex.
Steps for Finding the Best Letdown Setting:
- Start with the pump in stimulation mode (if available) or at a low suction level and a relatively fast speed. Stimulation mode, such as on the Momcozy M9, typically operates with lower suction but faster speed.
- Gradually increase the speed until milk begins to flow, typically within 1-2 minutes. Always monitor suction comfort levels to ensure they remain within your personal tolerance. Avoid exceeding what feels comfortable.
When using a pump like the Momcozy M9, it starts in Stimulation Mode with Suction Level 1 by default. You can adjust the suction level manually to find the setting that feels most comfortable.
What Is the Best Breast Pump Setting for Expression?
During the expression phase, the goal is to maximize milk extraction efficiently and comfortably. This phase mimics a baby’s slower, deeper sucking once milk flow is established. For effective expression:
- Switch to Expression Mode after milk starts flowing. Most electric breast pumps, such as the Momcozy M9, include an Expression Mode, which is typically characterized by stronger suction but slower speed to simulate deep, efficient sucking.
- If your pump does not have an Expression Mode but allows speed adjustments, you can manually lower the speed to mimic this phase. However, some pumps, such as the Momcozy M9, do not allow speed adjustments and instead focus on adjusting suction strength and modes.
- Gradually increase the suction strength to the highest comfortable level (Maximum Comfort Vacuum) for optimal milk flow.
The Momcozy M9 offers an Expression Mode specifically designed for this phase, with 15 suction levels to help users find their ideal settings.
Is It Better to Use Automatic Settings or Manual Settings?
Both automatic and manual settings have their advantages, and the choice depends on the user’s preferences and pumping needs:
Automatic Settings
The Momcozy M9 offers 3 Regular Pumping Modes—Stimulation, Expression, and Mixed—which can be controlled directly on the pump or via the app. In addition to these modes, the pump includes two advanced Pumping Patterns that are App Controlled only:
- Milk Boost™ Pattern: A pre-programmed 30-minute session designed to increase milk supply, with preset speed and suction level changes throughout the session for optimal efficiency. No manual adjustments are needed during pumping.
- Milk Relief™ Pattern: A pre-programmed 18-minute session tailored to ease fullness, offering gentle yet effective milk extraction with preset speed and suction level adjustments throughout.
For users who prefer greater customization, the Momcozy M9 app allows full control over individual settings. Users can manually adjust:
- The duration and suction levels for Stimulation, Expression, and Mixed modes.
- Combine these adjustments into a custom pattern, which can be saved as Personalized Preferences in the app for future use. Once saved, this custom pattern eliminates the need to manually adjust modes or suction levels during subsequent sessions.
Manual Settings
- Pros: Allows for full customization, which is helpful for adapting to daily changes in sensitivity or milk flow. Users can fine-tune suction strength and select the most suitable mode to align with their comfort and effectiveness.
- Cons: Requires more attention and adjustment, which might not be ideal for busy users.
The Momcozy M9 combines the best of both worlds. It offers pre-programmed settings for quick adjustments while allowing manual customization through the app. For example, the app’s MyFlow™ enables users to create a personalized pattern, combining stimulation and expression phases for an optimal and tailored pumping session.
