Breast pumping can be a vital part of your breastfeeding journey, helping you express milk for your baby while maintaining flexibility. But one of the most important factors to consider for a successful pumping experience is the fit of your breast pump flanges. A proper flange fit not only maximizes milk output but also ensures comfort and prevents potential damage to your breast tissue. In this blog, we'll take a deep dive into what breast pump flanges are, how they should fit, and how to measure for the correct size.

What Are Breast Pump Flanges?

Definition and Purpose

A breast pump flange is the part of the pump that fits over your nipple and areola to help extract milk. It creates a vacuum-like seal that allows the pump to draw milk from your breasts. Flanges come in various sizes to accommodate different nipple shapes and sizes, ensuring that the pump works effectively and comfortably.

Different Types of Flanges

There are several types of flanges designed to meet different needs and preferences:

• Standard Flanges: These are the most common and fit most breast shapes and sizes. They typically come in standard sizes, such as 24mm or 28mm.
• Wide-Base Flanges: Designed for women with larger or wider nipples, these flanges provide a better fit by offering a wider base.
• Soft Silicone Flanges: Made with flexible silicone, these flanges offer more comfort and a better seal by conforming to the shape of your breast.
• Adjustable Flanges: Some pumps, such as the MomMed electric breast pumps, include adjustable flanges with sizing tools like a measurement card, allowing you to customize the fit to suit your needs.

Why Proper Fit Matters

A proper flange fit is essential for efficient milk expression, as an ill-fitting flange can cause discomfort, inefficient milk extraction, and even long-term damage to your breast tissue. Too small of a flange may cause nipple pinching or chafing, while a flange that is too large can result in inefficient suction and less milk being pumped.

How Should Breast Pump Flanges Fit?

Nipple Placement

The first step to ensuring a proper flange fit is correct nipple placement. When you position the flange, your nipple should be centered in the tunnel (the part of the flange that fits over your nipple). If your nipple is too far to the side, the flange may not create the right suction, and the milk flow will be limited.

The goal is to make sure that the nipple is able to move freely in the flange tunnel without rubbing against the sides. This helps achieve a consistent and effective suction that will maximize milk production.

Areola Inclusion

While your nipple should be the primary focus of the flange, a small amount of the areola should also be included in the flange. Ideally, about 1 to 2 inches of the areola should be inside the flange. If too much of the areola is inside, it can result in discomfort and poor suction. On the other hand, if too little of the areola is included, the pump may not be able to create a good seal, making it harder to extract milk efficiently.

Suction Comfort

The suction created by the flange should feel firm but not painful. If you experience pain while pumping, it could be a sign that the flange is too small, too large, or improperly positioned. Adjusting the flange or switching to a different size can often solve this issue. It's important to find a flange that feels comfortable while still providing enough suction to express milk effectively.

How to Measure for the Correct Flange Size

Step-by-Step Measurement Guide

To ensure you have the correct flange size, it’s important to measure your nipple properly. Here’s a simple guide to help you find your ideal flange size:

1. Measure Your Nipple Diameter: Use a soft measuring tape or ruler to measure the diameter of your nipple at the widest point while keeping the tape snug but not tight.

2. Check for Areola Size: Take note of the size of your areola, as it will help determine how much of the areola should be included in the flange. The goal is to get a flange that fits comfortably around the nipple and some of the areola.

3. Choose the Right Size: Most modern breast pumps, like the MomMed wearable breast pumps, offer a range of flange sizes. If you're unsure of your size, use the measurement tools provided by the pump. Generally, a 24mm flange fits the majority of women, but it's essential to find the one that works for you.

Using Flange Sizing Tools

Many modern breast pumps, including wearable models, come with flange sizing tools to help you measure your nipple diameter accurately. These tools take the guesswork out of choosing the right size, ensuring you use the most effective flange for your body. Some pumps provide charts or guidelines to match your measurement to the available flange sizes.

Customizing Fit

If you find that standard flanges don’t work, consider a pump like the MomMed S21 Wearable Electric Pump, which features customizable flange sizes. This adjustable system allows you to swap flanges for a better fit as your needs change, especially during engorgement or postpartum adjustments. The S21 breast pump ensures a secure fit that enhances comfort and improves milk extraction.

Common Challenges with Flange Fitting

Finding the right flange size isn’t always straightforward, and several factors can affect how well your flange fits over time. Here are some common challenges you may encounter:

Breast Changes Over Time

Your breasts will naturally change during the course of breastfeeding, and these changes can impact how your flange fits. In the early stages of breastfeeding, hormonal fluctuations, changes in milk supply, and breast engorgement can cause your breasts to become larger, firmer, or more sensitive. As your milk supply stabilizes, your breasts may shrink slightly in size. These fluctuations may cause the flange that initially fit well to feel too tight or too loose later on. Regularly measuring your nipple and considering your breast's current size can help you adjust and find the best-fitting flange.

Pumping Pain or Nipple Trauma

Pumping pain or nipple trauma is often a clear sign that your flange doesn’t fit correctly. If your flange is too small, it can pinch, rub, or chafe your nipple, leading to soreness, redness, or even cracks. On the other hand, a flange that is too large can cause inefficient suction or excessive friction, which can also result in irritation. If you experience discomfort while pumping, it's essential to stop and reassess your flange size. Always check for signs of nipple trauma such as redness, swelling, or cracks, and experiment with different sizes until you find one that fits comfortably without causing pain.

Engorgement or Swelling

Engorgement can occur when your breasts become overly full with milk, often due to a missed pumping session or an oversupply. Swollen, firm breasts can make it difficult to achieve a proper seal with your pump, and you may find that your flange size needs adjustment. When you are engorged, your breasts may be larger and firmer, so using a slightly larger flange may help accommodate the increased volume and alleviate discomfort. Failing to adjust the flange size during engorgement can lead to further discomfort and improper milk extraction, so be mindful of your breast condition when pumping.

Tips for Ensuring a Good Fit

Ensuring your breast pump flange fits properly is key to a comfortable and effective pumping experience. Here are some tips to help you achieve the best fit:

Start with the Correct Size

It’s essential to begin with the correct flange size. A flange that is too small can cause pinching, soreness, or even damage to your nipple tissue, while a flange that is too large may lead to inefficient milk extraction and discomfort. Always measure your nipple size carefully before using a pump, and choose the size that closely matches your measurements. If you experience pain or difficulty while pumping, consider adjusting the flange size to see if a different fit helps.

Experiment with Different Sizes

Finding the perfect flange size can be a process of trial and error. If the initial size you choose doesn’t feel right, try experimenting with other options. Many breast pumps offer a range of flange sizes, so don't hesitate to switch sizes to find the one that works best for you. It may take some time to discover the optimal fit, but it's worth the effort to ensure your comfort and maximize milk output.

Consider Silicone Flanges

For added comfort, silicone flanges are a great alternative to traditional plastic ones. These flanges offer a softer, more flexible fit, which can reduce friction and irritation during pumping. Silicone can also provide better suction, making it an excellent option for those who find plastic flanges too rigid or uncomfortable. If you experience discomfort with standard flanges, silicone may be a worthwhile option to explore.

Replace Worn Flanges

Over time, flanges can wear out with regular use. Signs of wear include cracks, discoloration, or loss of elasticity. A worn flange may not form a proper seal, which can affect suction and make pumping less efficient. To maintain optimal performance, it's important to replace your flanges when they begin to show signs of damage. Regularly inspecting your flanges and replacing them as needed will help ensure that you get the best results from your pump.

Conclusion

Finding the right flange fit is crucial for a comfortable and efficient pumping experience. The correct size not only improves milk extraction but also helps minimize discomfort and protect your breast tissue. Taking the time to measure properly, experiment with different sizes, and use the appropriate tools will ensure you achieve the perfect fit. For instance, using a breast pump like the MomMed S21 wearable breast pump, which offers customizable flanges, can make it easier to tailor the fit to your unique needs. If you ever experience pain or notice any changes in your breast tissue, it's important to consult with your healthcare provider. Your health and comfort should always be your top priority throughout your breastfeeding journey.
