Getting to grips with your new breast pump can feel like a bit of a tech challenge at first. Between the different suction levels, modes, and speeds, it is easy to feel overwhelmed! However, understanding how breast pumping suction actually works is a game-changer. It makes your sessions much more comfortable and helps you express as much milk as possible for your little one.
How Do We Actually Measure Breast Pump Suction?
The strength of a breast pump is measured in millimetres of mercury (mmHg). This tells you how much vacuum pressure the motor is creating. Most pumps let you change these levels to find what feels right for you. For instance, portable wearable pumps usually range from 200 to 300 mmHg. If you are looking for more power, hospital-grade wearable pumps can reach up to 300-350 mmHg. Being able to adjust this means you can customise the experience to your own body's needs.
SEA Mummy Tip: In Singapore, many mummies use their CDA (Child Development Account) funds to purchase hospital-grade pumps at approved baby fairs. Check if your chosen model is eligible to maximise your Baby Bonus benefits!
Why Does "Stronger Suction" Not Always Mean More Milk?
A common myth is that turning the suction up to the max will get you more milk faster. In reality, settings that are too high can actually pinch your breast tissue and block your milk ducts. This can slow down your flow instead of speeding it up. High suction can also cause pain, which prevents your body from relaxing—a key factor in releasing milk.
Medical studies suggest that the "Maximum Comfort Vacuum" (MCV) is the "sweet spot". This is the highest setting that still feels comfortable for you. When you are relaxed and pain-free, your milk volume and flow are naturally optimised. Comfort should always come before power.
What Is Your Personal Ideal Pumping Suction Level?
The "best" level is completely unique to you. It might even change depending on the time of day or how tired you feel. To find your own Maximum Comfort Vacuum (MCV), follow these simple steps:
Start on the lowest possible setting when you turn the pump on.
Slowly turn the suction up until it starts to feel slightly "pinch-y" or uncomfortable.
Immediately drop it back down one level to where it feels firm but perfectly comfortable.
A good setting helps your milk flow without causing any soreness. For mummies in Malaysia and Singapore who often pump while working from home, using a nursing pillow can also help you sit up straight and stay relaxed, which prevents backaches during your 20-minute sessions.
SEA Mummy Tip: If you are pumping in a cold office in Raffles Place or KL Sentral, the air-con can inhibit your letdown. Try using a warm shawl or a warm drink to help your body relax into the session.
What Are the Different Settings on a Modern Breast Pump?
Most devices have two main adjustments: how hard it pulls (suction) and how fast it pulls (speed). These are designed to copy the way a real baby nurses, which happens in two stages:
Stimulation Phase (Massage Mode): This mimics the fast, light sucks a baby makes at the start to "wake up" the milk. Electric breast pumps use high speed and low suction here. On models like the Momcozy M9 or M5, this is the default mode to help you start gently.
Expression Phase: Once your milk starts flowing (the letdown), the baby slows down and takes deeper sucks. The pump mimics this with slower speeds and higher suction.
Mixed Mode: Some pumps offer a cycle that toggles between both to keep the milk flowing while keeping your nipples comfortable.
The Momcozy M5 is a great choice for SEA mummies, offering stimulation, expression, and mixed modes with 9 levels of suction reaching up to 280 mmHg.
For even more control, the Momcozy M9 connects to an app. This allows you to fine-tune your settings from your phone—perfect for discreet pumping during a Zoom call or while commuting on the MRT.
The "letdown" is when your milk begins to spray or flow steadily. To trigger this, you need fast, flutter-like movements. Using a high-speed but low-suction setting is the best way to encourage your milk to drop.
Quick Steps for a Faster Letdown:
Select "Stimulation Mode". This starts with fast, light pulses.
Stay on this mode until you see milk droplets start to fill the collector, which usually takes about 2 minutes.
The Momcozy M5 automatically starts on Level 1 Stimulation, so you don't have to worry about a sudden "shock" to your system when you first turn it on.
Which Settings Work Best for the "Expression" Stage?
Once the milk is flowing, you want to empty the breast efficiently. This requires a deeper pull.
Switch to "Expression Mode". This slows down the rhythm and increases the suction depth.
If your pump doesn't have a specific mode, manually lower the speed and increase the suction slightly.
Always stay within your Maximum Comfort Vacuum. If it hurts, turn it down!
With the M9 model, you have 15 different levels to choose from, making it very easy to find the exact strength that works for your body.
Is It Better to Use Preset Modes or Manual Control?
Both have their perks depending on how busy your day is!
The Convenience of Automatic Settings
The Momcozy M5 and M9 come with standard modes like Stimulation and Expression. However, the M9 app takes it further with specialised patterns:
Milk Boost™ Pattern: A 30-minute automated session designed to help boost your supply (perfect for mummies worried about returning to work).
Milk Relief™ Pattern: A shorter 18-minute session to quickly ease engorgement without over-stimulating.
The Flexibility of Manual Adjustments
Pros: You can adapt to how your body feels each day. If you have a blocked duct or are feeling sensitive, you can keep the suction extra low.
Cons: It requires you to keep track of the time and switch modes yourself, which can be tricky if you are multi-tasking.
The best approach for most SEA mummies is the M9's "MyFlow™" feature. You can create your own perfect 20-minute pattern once, save it in the app, and just press "Start" every time after that!
Common Questions from SG & MY Mummies
Can I pump discreetly while at the office or in a shopping mall?
Absolutely. The M9 and M5 are lightweight (as light as a small apple!) and run very quietly (under 50dB). You can easily wear them under your blouse while working at your desk or sitting in a nursing room at Takashimaya or Pavilion.
How do I keep the pump from slipping?
A good pumping bra is essential. In our humid weather, look for breathable cotton or moisture-wicking fabrics. Make sure the bra is snug enough to hold the pump firmly against your skin to keep the suction seal tight.
The M9 has a 30-minute safety shut-off. If you are doing "power pumping" to increase your supply, just turn it back on for your next interval.
Is it possible to track how much I express?
Yes, the Momcozy App allows you to log your milk volume. This is great for keeping an eye on your stash and ensuring you have enough for the nanny or infant care.
What is the best way to avoid spills?
When you finish, lean forward slightly before breaking the seal with your finger. Keep the container upright until you transfer the milk into a storage bag or bottle.
Can I use the pump while it is plugged into the charger?
No, for your safety, these pumps won't operate while charging. Make sure to charge them after your last session of the night so they are ready for the morning.
How do I clean my pump in a communal office kitchen?
The parts are easy to pull apart. Rinse them with cool water first to remove proteins, then use warm soapy water. Many mummies keep a dedicated "pumping kit" bag to keep everything hygienic.
What should I do if pumping feels painful?
Pain is a sign that something is wrong. Usually, the suction is too high, or your flange (the funnel part) is the wrong size. In Singapore, you can consult a lactation expert if the pain continues.
Why is the nipple position so important?
If your nipple isn't centred, it will rub against the sides, causing "friction burn" and reducing your milk flow. Always double-check your alignment before you hit the start button.
How long should I pump for?
Usually 15 to 20 minutes is enough. If nothing is happening after 5 minutes, take a break, drink some water, and try again later.
What if my breasts feel different every day?
That is normal! Factors like our spicy local food, stress at work, or how much water you've had can affect sensitivity. Just adjust your suction level to match how you feel in the moment.
How much milk can the collector hold?
It holds about 120ml. If you are a "super-producer", keep an eye on it so it doesn't overflow!
Is it safe to pump while doing housework or lying down?
We don't recommend lying down as it can cause leaks. While you can move around the house, avoid anything too strenuous that might break the suction seal.
Are there any Singapore-specific maternity benefits for pumping?
Under the MOM (Ministry of Manpower) guidelines, most employers are encouraged to provide nursing breaks. Also, check if your corporate insurance covers lactation consultations!
What if I am a Malaysian mummy working in SG?
Ensure you have a reliable power bank for the commute! If you are covered by SOCSO (PERKESO) in Malaysia, check your specific scheme for any wellness or maternity benefits that might apply.
The Final Word
Mastering your breast pump doesn't have to be a headache. The most important thing to remember is that comfort is king. You don't need to use the highest suction to get the best results. By finding your "Maximum Comfort Vacuum" and using the right modes, you can make pumping a stress-free part of your day. Take it one session at a time—you're doing a great job, Mummy!
