How to Choose the Right Flange Size for Your Spectra Breast Pump

Introduction to Flange Size and Breast Pumping

In my London clinic, I often see mums struggling with breast pumping due to incorrect flange sizes. As an International Board Certified Lactation Consultant (IBCLC), I recommend using the right flange size to ensure comfortable and efficient milk expression, in line with the NHS guidelines (NICE CKS, 2020). You can find more information on breastfeeding and breast pumping on the NHS website. For a seamless pumping experience, consider investing in the TheRelievoo Wearable Pump, which comes with a range of flange sizes, including the All-Size Flange Inserts (10pc) for £19.90, perfect for mums on-the-go in busy London.

Why Flange Size Matters

A mum I worked with last month at NCT classes in Camden had issues with nipple trauma and low milk expression due to an ill-fitting flange. The NCT recommends that mums use the correct flange size to prevent such issues. Using the right flange size can increase milk expression by up to 20% and reduce pumping time by 15% (NHS, 2020). I recall she said,

"I was in so much pain while pumping, but after switching to the right flange size, it felt like a weight had been lifted off my shoulders. The relief was palpable, and I could finally express milk comfortably."
This experience highlights the importance of proper flange sizing.

Right Flange Size Breast Pump Spectra

To determine the right flange size for your Spectra breast pump, follow these steps:

  1. Measure your nipple diameter using a ruler or a flange sizing guide, taking care to ensure accuracy.
  2. Choose a flange size that is 1-2mm larger than your nipple diameter, allowing for a comfortable fit.
  3. Consider the shape of your nipple and the type of breast pump you are using, as this can affect the fit and performance of the flange.

How to Measure Flange Size for Breast Pump Spectra

Measuring your flange size is crucial to ensure a comfortable and efficient pumping experience. You can use a flange sizing guide or consult with a lactation consultant like myself. The Tommy's website provides a range of resources on breastfeeding and breast pumping, including information on flange sizing. I recommend visiting their website for more information and support.

Breast Pump Flange Size Chart Spectra

Here is a general flange size chart for Spectra breast pumps:

  • 17mm: suitable for mums with smaller nipple diameters, often those with an 'A' cup size or smaller.
  • 19mm: suitable for mums with average nipple diameters, often those with a 'B' or 'C' cup size.
  • 21mm: suitable for mums with larger nipple diameters, often those with a 'D' cup size or larger.
  • 24mm: suitable for mums with very large nipple diameters, often those with an 'E' cup size or larger.

Common Mistakes to Avoid

One common mistake mums make is using a flange size that is too small, which can lead to nipple trauma and low milk expression. Another mistake is not adjusting the flange size as the nipple diameter changes over time, such as during pregnancy or after childbirth. The La Leche League GB provides a range of resources on breastfeeding and breast pumping, including information on common mistakes to avoid. I recommend visiting their website for more information and support.
