Why the Right Flange Matters: Enhancing Your Pumping Experience

Breastfeeding is a deeply personal and important journey for many mothers. For those who rely on breast pumps, whether occasionally or as a primary method of milk expression, the right tools can make all the difference. Among these tools, the breast pump flange plays a pivotal role. Often overlooked, this simple component is crucial to ensuring a comfortable and efficient pumping experience. Using the correct flange size and type not only enhances comfort but also maximizes milk output, making your pumping sessions more effective and less stressful.

1. What Are Breast Pump Flanges, and Why Are They Important?

A breast pump flange, also known as a breast shield, is the funnel-shaped part of the pump that fits over your nipple and areola. Its primary role is to create a seal around your breast, allowing the pump to create suction that expresses milk. The flange’s size and fit are crucial because an improper fit can lead to discomfort, reduced milk output, and even damage to breast tissue. A well-fitting flange, on the other hand, can make pumping more comfortable and efficient, helping you maintain or even increase your milk supply​.

2. How Can Using the Wrong Flange Size or Type Affect Your Pumping Experience?

Using a flange that doesn’t fit properly can cause several issues. If the flange is too small, your nipple might rub against the sides of the tunnel, leading to pain, soreness, and even skin damage. A too-large flange might pull in too much of your areola, which can cause discomfort and reduce the effectiveness of the pump, leading to lower milk production. In some cases, an ill-fitting flange can also lead to clogged milk ducts, which can be painful and potentially lead to mastitis, an infection of the breast tissue.

3. What Are the Signs That You're Using the Wrong Flange?

Recognizing the signs of an incorrect flange fit is key to improving your pumping experience. Common indicators include:

  • Nipple pain or soreness during and after pumping.

  • Redness or discoloration around the nipple area.

  • Nipple rubbing against the sides of the flange tunnel.

  • Excessive areola tissue being drawn into the flange.

  • Breasts still feeling full even after a pumping session

If you experience any of these symptoms, it may be time to reassess your flange size or consult with a lactation expert, like The Milk Effect.

4. How Do You Choose the Right Flange for Your Needs?

Choosing the right flange size starts with accurately measuring your nipple. To do this, measure the diameter of your nipple at its base before pumping. In most cases, it is better to add 0-2 millimeters to this measurement to determine your ideal flange size. Now adding 0-2 millimeters is not ideal for everyone so it is better to get help instead of trying to figure it out on your own. It’s important to note that your flange size may change over time, especially postpartum, so reassess regularly. If you’re still unsure about your size, The Milk Effect offers nipple sizing and recommendations

5. What Are the Different Types of Flanges Available, and Who Are They Best Suited For?

Breast pump flanges come in various types and materials, each suited for different needs:

  • Standard Plastic Flanges: Common in most pump kits, these work for many users but might lack flexibility.

  • Silicone Flanges: Offer a softer, more flexible fit, ideal for sensitive skin.

  • Custom-Fit Flanges: Available in a variety of sizes to match specific nipple measurements, providing a more personalized fit.

  • Angled Flanges: Designed to reduce strain on the back and shoulders, these are great for frequent pumpers​

6. Who Should You Consult if You're Having Trouble Finding the Right Flange?

If you’re struggling to find the right flange size or experiencing ongoing discomfort, it’s advisable to consult an International Board Certified Lactation Consultant (IBCLC). These professionals can help you determine the best flange size for your needs, troubleshoot any issues, and provide support to ensure your pumping journey is as smooth as possible.
