Willow Sizing Insert Set: How to Measure Your Nipple for the Perfect Fit

Getting the right fit for your breast pump is crucial for both comfort and milk output. If you're using a Willow wearable pump, the Willow Sizing Insert Set can help you achieve a personalized fit. This guide will walk you through how to measure your nipple accurately and select the correct flange size.

Whether you're a first-time pumper or have been pumping for a while, understanding your measurements can make a significant difference. A proper fit prevents discomfort, maximizes milk expression, and reduces the risk of clogged ducts. Let's dive into the details.

Why Nipple Measurement Matters for Willow Pumps

The flange size is the funnel-shaped part of the pump that fits over your nipple. If the flange is too small, it can cause friction and pain; if too large, it may not create an effective seal, leading to reduced milk output. For Willow pumps, which are worn inside your bra, an accurate fit is even more important because the pump relies on a secure seal to collect milk efficiently.

Many women assume that one size fits all, but nipple sizes vary widely and can change over time due to factors like pregnancy, breastfeeding, or pumping frequency. Measuring your nipple regularly ensures you're using the correct size, which can improve your pumping experience and help you reach your breastfeeding goals.

• Prevents nipple pain and damage
• Improves milk flow and output
• Reduces the risk of clogged ducts and mastitis
• Enhances overall comfort during pumping

Step-by-Step Guide to Measuring Your Nipple

To measure your nipple for a Willow pump, you'll need a ruler or a measuring tape with millimeter markings. It's best to measure before pumping or feeding, as your nipple may be slightly larger after stimulation. Here's how to do it:

First, gently stimulate your nipple to become erect, as this is the size it will be during pumping. Then, measure the diameter at the base of the nipple, excluding the areola. Use the ruler to get the measurement in millimeters. Repeat this process a few times to ensure accuracy, as your nipple size can fluctuate slightly.

Once you have your measurement, refer to the Willow sizing chart to determine the appropriate flange size. The Willow Sizing Insert Set includes multiple sizes, allowing you to switch between them as needed. Remember that you may need a different size for each breast, so measure both.

• Measure when your nipple is erect for the most accurate reading
• Use a ruler with millimeter markings for precision
• Measure both breasts, as sizes can differ
• Re-measure periodically, especially after significant weight changes or breastfeeding milestones

Using the Willow Sizing Insert Set

The Willow Sizing Insert Set is designed to help you customize the fit of your Willow pump. It typically includes a variety of insert sizes that fit into the pump's flange to reduce the opening, ensuring a snug but comfortable fit. This is especially useful if your nipple size falls between standard flange sizes.

To use the inserts, simply choose the size that matches your measurement and place it inside the flange before pumping. Make sure it sits securely and creates a smooth surface. The inserts are easy to clean and can be used with your regular pump parts. If you're unsure which size to choose, the set may come with a sizing card or you can consult the Willow website for guidance.

For those who prefer a more comprehensive solution, consider the Willow Go® Backup Parts Set, which includes essential components to keep your pump in top condition. Having backup parts ensures you're never without a clean, functional pump when you need it.

• Inserts are available in multiple sizes to accommodate various nipple diameters
• They are made of soft, flexible material for comfort
• Easy to insert and remove for cleaning
• Compatible with most Willow pump models

Tips for a Comfortable and Efficient Pumping Session

Once you've found the right flange size, there are a few additional tips to ensure your pumping sessions are as comfortable and productive as possible. First, ensure your nipple is centered in the flange before starting the pump. This helps create an even suction and prevents friction.

Second, consider using a lubricant like nipple cream or a few drops of olive oil on the flange to reduce friction. However, avoid using oil-based products if you're using the Willow 360® pump, as it may affect the sensors. For other models, a small amount can be helpful.

Third, pay attention to your let-down reflex. Relaxing and thinking about your baby can help stimulate milk flow. Some mothers find that looking at photos or listening to audio of their baby helps. Additionally, staying hydrated and eating a balanced diet can support milk production.

If you experience discomfort during pumping, check the fit again. You may need a different insert size or a different flange altogether. The Willow Sizing Insert Set allows you to experiment with different sizes to find what works best for you.

• Center your nipple in the flange before turning on the pump
• Use a water-based lubricant if needed
• Stay relaxed and hydrated for better let-down
• Re-evaluate your fit if you notice any pain or reduced output
