What Size Breast Pump Flanges to Get: A Comprehensive Guide

When it comes to breastfeeding, using a breast pump can be a game-changer for many mothers. However, one of the most overlooked yet critical aspects of pumping is selecting the right flange size. The flange, the part of the breast pump that fits over the nipple and areola, plays a significant role in comfort and efficiency. Choosing the wrong size can lead to discomfort, reduced milk output, and even damage to breast tissue. So, what size breast pump flanges to get? Let’s dive into everything you need to know to make the right choice.

Why Flange Size Matters

The flange size directly impacts your pumping experience. A flange that’s too small can compress the nipple, causing pain and restricting milk flow. On the other hand, a flange that’s too large can pull too much of the areola into the tunnel, leading to discomfort and inefficient milk removal. The right size ensures that your nipple moves freely within the tunnel without rubbing against the sides, allowing for optimal milk expression and comfort.

How to Measure Your Nipple for the Right Flange Size

Measuring your nipple is the first step in determining the correct flange size. Here’s how to do it:

1. Use a ruler or a measuring tape to measure the diameter of your nipple. Measure only the nipple, not the areola.
2. Add 2-3 millimeters to the diameter to determine the appropriate flange size. For example, if your nipple measures 15 millimeters, a flange size of 17-18 millimeters would be ideal.
3. Repeat the process for both nipples, as they may not be the same size.

Keep in mind that your nipple size may change over time, especially during the early weeks of breastfeeding. It’s a good idea to re-measure periodically to ensure you’re still using the correct size.

Common Flange Sizes and Their Uses

Breast pump flanges typically come in a range of sizes, from small to large. Here’s a breakdown of common sizes and who they’re best suited for:

• Small (21mm): Ideal for mothers with smaller nipples, typically around 19mm in diameter.
• Medium (24mm): The most common size, suitable for nipples around 21-22mm in diameter.
• Large (27mm): Best for mothers with larger nipples, around 24-25mm in diameter.
• Extra Large (30mm+): Designed for those with very large nipples or those who experience significant swelling during pumping.

If your nipple size falls between standard sizes, it’s generally recommended to choose the next size up for comfort.

Signs You’re Using the Wrong Flange Size

Using the wrong flange size can lead to a host of issues. Here are some signs that your current flange may not be the right fit:

• Pain or discomfort: If pumping is painful, especially around the nipple, your flange may be too small.
• Reduced milk output: Inefficient milk removal can be a sign that the flange is too large or too small.
• Nipple swelling or redness: This can indicate that the flange is causing friction or compression.
• Areola being pulled into the tunnel: If a significant portion of your areola is being drawn into the flange, it’s likely too large.

If you’re experiencing any of these issues, it’s worth re-measuring your nipples and trying a different flange size.

Tips for Finding the Perfect Fit

Finding the right flange size may require some trial and error. Here are some tips to help you along the way:

• Start with the standard size: Most breast pumps come with a medium-sized flange (24mm). This is a good starting point, but don’t hesitate to adjust if needed.
• Consult a lactation consultant: A professional can help you measure your nipples and recommend the best flange size for your needs.
• Use silicone inserts: If you’re between sizes or find standard flanges uncomfortable, silicone inserts can help customize the fit.
• Monitor your comfort and output: Pay attention to how you feel during and after pumping, as well as your milk output. These are good indicators of whether your flange size is working for you.

How to Adjust Your Pumping Technique for Better Results

Even with the right flange size, your pumping technique can impact your comfort and efficiency. Here are some tips to optimize your pumping sessions:

• Ensure a proper seal: The flange should fit snugly against your breast to create a vacuum. If there’s a gap, milk may not be effectively removed.
• Use lubrication: Applying a small amount of nipple cream or coconut oil to the flange can reduce friction and make pumping more comfortable.
• Adjust the suction level: Start with a lower suction level and gradually increase it to a comfortable setting. High suction doesn’t always mean better milk removal.
• Take breaks: If you’re pumping for extended periods, take short breaks to relieve pressure and prevent discomfort.

When to Replace Your Flanges

Flanges can wear out over time, especially with frequent use. Here are some signs that it’s time to replace them:

• Cracks or damage: Any visible damage to the flange can affect its performance and hygiene.
• Loss of suction: If you notice a decrease in suction, it could be due to worn-out flanges.
• Change in nipple size: If your nipple size has changed due to pregnancy, breastfeeding, or other factors, you may need a new flange size.

Replacing your flanges regularly ensures that you continue to have a comfortable and efficient pumping experience.

Custom Flanges: Are They Worth It?

For some mothers, standard flange sizes may not provide the perfect fit. Custom flanges, which are tailored to your exact nipple measurements, can be a great solution. While they may be more expensive, they offer a precise fit that can enhance comfort and milk output. If you’ve struggled to find a standard flange that works for you, custom flanges may be worth considering.

Final Thoughts on Choosing the Right Flange Size

Selecting the right breast pump flange size is essential for a comfortable and effective pumping experience. By measuring your nipples, understanding common sizes, and paying attention to signs of discomfort, you can find the perfect fit. Don’t be afraid to experiment with different sizes or seek professional advice if needed. Remember, the right flange size can make all the difference in your breastfeeding journey.
