Wondering if BabyBuddha flange inserts work with 24mm flanges? This guide explains compatibility, fit tips, and how to get the most comfortable pumping experience.

If you're using a BabyBuddha pump with 24mm flanges, you might be wondering whether flange inserts can help you achieve a better fit. The short answer is yes—many BabyBuddha flange inserts are designed to work with 24mm flanges, but the key is choosing the right insert size and ensuring it sits securely.

In this guide, we'll explain how flange inserts work, which sizes are compatible with 24mm flanges, and how to get the most comfortable and effective pumping session. Whether you're new to pumping or looking to fine-tune your setup, this practical advice will help you make an informed choice.

How Flange Inserts Work with 24mm Flanges

Flange inserts are silicone or plastic adapters that reduce the internal diameter of a flange, allowing a smaller nipple to fit more snugly. When placed inside a 24mm flange, an insert effectively creates a smaller tunnel, which can improve comfort, milk flow, and overall pumping efficiency.

For BabyBuddha pumps, inserts are typically available in sizes like 13mm, 15mm, and 17mm. These are designed to fit standard 24mm flanges, so you can use them with your BabyBuddha wearable or primary pump. The insert should sit flush against the flange wall, creating a smooth surface for your nipple to move without friction.

It's important to note that not all inserts are universal. Always check compatibility with your specific flange model. BabyBuddha's own inserts are tailored to their 24mm flanges, ensuring a secure fit and consistent performance.

  • Measure your nipple diameter to find the right insert size; it should be about 1-2mm larger than your nipple at rest.
  • Ensure the insert is fully seated in the flange—no gaps or wobbling—before pumping.

Choosing the Right Insert Size for 24mm Flanges

The most common insert sizes for 24mm flanges are 13mm, 15mm, and 17mm. To choose the right one, measure your nipple diameter (excluding the areola) when it's at rest. Add 1-2mm for comfort and to allow for slight swelling during pumping.

For example, if your nipple measures 12mm, a 13mm insert would be a good match. If you're between sizes, it's often better to go slightly larger to avoid pinching. You can also try different sizes to see which feels most comfortable and yields the best milk output.

BabyBuddha offers a range of inserts, including the Flange Inserts – 13mm (2-pack) and Flange Inserts – 15mm (2-pack), which are specifically designed for their 24mm flanges. These inserts are easy to insert and remove, making them a convenient option for daily use.

  • Start with the size that matches your measurement, then adjust based on comfort and output.
  • If you experience nipple pain or rubbing, try a larger insert size.

Step-by-Step: Using Inserts with Your BabyBuddha Flanges

Using a flange insert is simple, but proper placement is key. First, ensure your flange and insert are clean and dry. Then, gently press the insert into the flange tunnel, starting from the back and working toward the front. The insert should sit evenly, with no folds or bulges.

Once in place, attach the flange to your BabyBuddha pump as usual. Check that the insert doesn't shift during pumping—if it does, it may be the wrong size or not seated properly. Remove and reinsert if needed.

After pumping, remove the insert and clean it thoroughly with warm, soapy water. Regular care extends the life of your inserts and keeps them hygienic.

  • Keep spare inserts on hand—they're small and easy to misplace.
  • If you use multiple pumps, consider buying a bundle of inserts for convenience.

Compatibility with BabyBuddha Wearable and Primary Pumps

BabyBuddha flange inserts are designed to work with both the BabyBuddha® 3.0 Primary Portable Breast Pump with EasyFit Kit and the BabyBuddha Wearable Breast Pump. In both cases, the 24mm flanges are the standard size, and inserts can be used to customize the fit.

For the wearable pump, inserts fit into the expression cups, which use 24mm flanges. The same sizing principles apply, but you'll want to ensure the insert doesn't interfere with the cup's seal or the pump's suction.

If you're unsure about compatibility, check the product description or contact BabyBuddha support. Using the correct insert ensures optimal suction and comfort, so it's worth the extra verification.

  • For wearable pumps, test the insert with the cup lid on to ensure a proper seal.
  • Some users find that a 17mm insert works best for wearable pumps due to the angle of the cup.

Tips for Maximizing Comfort and Milk Output

A proper fit is the most important factor in comfortable, efficient pumping. Inserts help, but you should also pay attention to your pump's suction levels and session duration. Start on a low suction setting and gradually increase until you find what's comfortable.

If you experience discomfort or reduced output, reassess your insert size. It's also worth checking that the insert is not worn or damaged—replacing inserts regularly can prevent issues.

Many parents find that using a lubricant like coconut oil on the insert can reduce friction and improve comfort. Just be sure to clean thoroughly afterward.

  • Replace inserts every few months or if they show signs of wear.
  • Keep a spare set of inserts in your pumping bag for emergencies.

BabyBuddha flange inserts are fully compatible with 24mm flanges, offering a simple way to achieve a custom fit for better comfort and milk output. By choosing the right size and following proper insertion and care steps, you can make your pumping experience more comfortable and efficient. Whether you're using a wearable or primary pump, inserts are a practical investment in your pumping journey.
