How an IBCLC Helps With a Breast Pump & Flange Fitting Consultation
Pumping is supposed to be comfortable and efficient, and when it isn’t, the most common (and most overlooked) reason is flange size. Many parents pump for months with the default size that came in the box, never realizing a small change could transform the experience.
Why fit matters so much
A flange that’s too large or too small can cause pain, reduce milk output, and even affect supply over time. The right fit lets your nipple move freely, drains the breast more effectively, and makes each session shorter and more comfortable.
Good to know: flange sizing is based on your nipple diameter, not breast size, and it can change over the course of your feeding journey. A quick reassessment now and then is completely normal.
How a virtual fitting works
- You send a few photos and your pump’s make and model through a secure platform.
- You measure with a printable ruler I provide.
- I recommend a flange or insert size, with links to buy exactly what you need.
- We meet for a short live session to confirm the fit is comfortable and effective.
Flange fitting is also included automatically in every full IBCLC consultation, so if you’re already booking a feeding visit, it’s part of the care.
