5 Common Pumping Mistakes and How to Avoid Them

Pumping can be a lifesaver for breastfeeding moms—providing flexibility, a backup supply, and peace of mind. But let’s face it: pumping isn’t always intuitive, and it’s easy to make mistakes that can lead to frustration, discomfort, or even a dip in milk supply. These 5 common pumping mistakes are something we see time and time again with moms.

The good news? These common pitfalls are completely avoidable with a little knowledge and preparation. Whether you’re an exclusive pumper or just looking to build a freezer stash, these five tips will help you make the most of your pumping routine and avoid the most common mistakes.

Mistake 1: Using the Wrong Pump

Not all pumps are created equal, and choosing the wrong one for your needs can lead to frustration, low milk output, and wasted time.

• Why It Matters: A pump that doesn’t align with your breastfeeding goals or lifestyle can make pumping harder than it needs to be. For example, a hospital-grade pump is ideal for exclusive pumpers, while a wearable pump like the Willow may be better for on-the-go moms.
• How to Avoid It:
  • Assess Your Needs: Think about how often you’ll pump and where you’ll use your pump (at home, at work, or on the go).
  • Do Your Research: Look for reviews and recommendations on pumps that fit your situation.
  • Consult an IBCLC: Lactation consultants can guide you in selecting the best pump for your body and your goals.

Mistake 2: Using the Wrong Flange Size

The flange—the part of the pump that fits over your breast—is often overlooked but plays a huge role in pumping comfort and efficiency. This is the most common pumping mistake we see with our clients.

• Why It Matters:
  • A flange that’s too small can cause pain and restrict milk flow, while a flange that’s too large may reduce suction and leave milk behind.
• How to Avoid It:
  • Measure Your Nipple Diameter: Use a ruler or nipple measuring tool to find the diameter of your nipple (not the areola) in millimeters. Match this measurement to the pump manufacturer’s flange size guide.
  • Reassess Over Time: Your nipple size may change over the course of your breastfeeding journey, so it’s important to reevaluate your flange size periodically.
  • Use Inserts: If your size falls between standard flange options, use silicone inserts for a custom fit.

Mistake 3: Inconsistent Pumping Schedule

Pumping sporadically or skipping sessions can confuse your body and reduce your milk supply over time.

• Why It Matters:
  • Milk production operates on a supply-and-demand system. Irregular pumping tells your body that less milk is needed, which can lead to a dip in supply.
• How to Avoid It:
  • Stick to a Schedule: Aim to pump every 2–3 hours if you’re exclusively pumping or as often as your baby typically feeds.
  • Set Reminders: Use alarms or a pumping app to stay consistent, especially during busy days.
  • Power Pump if Needed: If you miss a session or notice a drop in supply, try power pumping (10 minutes on, 10 minutes off for an hour) to stimulate milk production.

Mistake 4: Not Replacing Pump Parts

Worn-out pump parts can decrease suction and efficiency, making pumping sessions less productive.

• Why It Matters:
  • Over time, parts like membranes, valves, and tubing lose their integrity, which can reduce milk flow and prolong pumping sessions.
• How to Avoid It:
  • Know Replacement Guidelines: Check your pump’s manual for recommendations, but as a general rule:
    • Replace membranes and valves every 1–3 months.
    • Replace tubing every 6 months or if it shows signs of wear.
  • Inspect Regularly: Look for cracks, discoloration, or changes in suction.
  • Keep Spares on Hand: Stock up on replacement parts so you’re not caught off guard.

Mistake 5: Skipping Hand Expression

Many moms rely solely on the pump to remove milk, but adding hand expression can significantly improve milk output.

• Why It Matters:
  • Hand expression helps fully empty the breasts, which can increase supply and prevent clogged ducts or engorgement.
• How to Avoid It:
  • Combine Pumping with Hand Expression:
    • Before pumping: Gently massage your breasts to stimulate letdown.
    • During pumping: Use your hands to compress and massage areas that feel firm.
    • After pumping: Spend a few minutes hand-expressing to remove any remaining milk.

Bonus Tips for Pumping Success

• Create a Comfortable Setup:
  • Choose a space with a supportive chair, a hands-free pumping bra, and essentials like water, snacks, and a phone charger.
• Stay Hydrated and Nourished:
  • Your body needs extra fluids and calories to produce milk, so don’t skimp on hydration or nutrition.
• Don’t Compare Output:
  • Milk output varies between moms, so focus on what works for you and your baby rather than comparing yourself to others.

What next?

Pumping doesn’t have to be a source of frustration. By avoiding these common mistakes and following simple, effective strategies, you can make pumping more comfortable, productive, and rewarding. Every ounce of milk you pump is a gift for your baby—and a testament to your dedication as a mom.
