Why Medela Pump In Style Flanges Are Necessary
From my experience, using the Medela Pump In Style flanges has made a huge difference in my breastfeeding journey. The flanges create a comfortable and secure seal around my breasts, which helps maximize milk flow and reduce any discomfort during pumping sessions. Without the right fit, pumping can feel frustrating and even painful, but these flanges fit perfectly and make the whole process much smoother.
I also noticed that having the correct flange size prevents nipple damage and irritation, which is so important when you’re pumping frequently. The Medela Pump In Style flanges are designed specifically for compatibility with the pump, ensuring efficiency and comfort. For me, this meant less stress and more milk, which is exactly what I needed to keep going. Overall, the right flanges are essential because they protect my comfort and help me get the most out of every pumping session.
My Buying Guides on Medela Pump In Style Flanges
When I first started using the Medela Pump In Style breast pump, I quickly realized how important the right flanges are for comfort and efficiency. Finding the perfect fit made a huge difference in my pumping experience, so I want to share what I’ve learned to help you choose the best Medela Pump In Style flanges for your needs.
Why Flange Size Matters to Me
The flange is the part that fits over the nipple and breast, and its size can affect both comfort and milk flow. I discovered that using the wrong size flange caused discomfort and sometimes even reduced my milk output. Medela offers flanges in various sizes, typically ranging from 21mm to 36mm. I recommend measuring your nipple diameter carefully to find the best match. If your flange is too small, it can pinch or cause soreness; if too large, it might not create the right suction.
Types of Medela Pump In Style Flanges
While the basic design remains consistent for the Pump In Style model, Medela offers different flange styles and materials:
- Standard Flanges: These are the classic hard plastic flanges that come with most kits. They’re durable and easy to clean.
- SoftFit Flanges: I found these softer silicone options gentler on my skin, especially during longer pumping sessions.
Think about what feels more comfortable for you, especially if you have sensitive skin or experience nipple soreness.
How to Choose the Right Size
To find your flange size, I measured the diameter of my nipple (not including the areola) in millimeters. You can do this by:
- Using a ruler or measuring tape.
- Measuring right after a feeding when your nipple is at its natural size.
- Comparing your measurement to Medela’s size chart.
If you’re between sizes, I found it helpful to try both sizes to see which felt better during pumping.
Comfort and Fit Tips from My Experience
- Always check for redness or discomfort after pumping; it’s a sign your flange might not fit well.
- Using a nipple cream can reduce irritation.
- Make sure the flange creates a good seal without causing pain.
- Consider trying different flange styles if you experience persistent discomfort.
Cleaning and Maintenance
I keep my flanges clean by washing them with warm, soapy water after each use and occasionally sterilizing them. Proper cleaning helps maintain hygiene and extends the life of the flanges. Avoid using harsh chemicals that can degrade the material.
Where to Buy and What to Expect Price-Wise
I purchased my replacement flanges from reputable online retailers and local baby stores. Prices vary depending on size and type, but expect to pay around $15 to $25 for a set. It’s worth investing in good-quality flanges to ensure comfort and efficiency.
Final Thoughts
Choosing the right Medela Pump In Style flanges made a big difference in my pumping routine. Taking the time to measure and try different sizes and types helped me avoid discomfort and pump more effectively. I hope my guide helps you find your perfect fit and makes your pumping experience a little easier!
