Why the Right Flange Size Matters?

  • Greater Comfort

    A well-fitted flange makes pumping comfortable and eliminates pain.

  • Healthy Nipples & Breasts

    No more friction,  soreness or clogged ducts.

  • More Efficient Milk Extraction

    Proper sizing improves milk flow and can shorten pumping sessions.

  • Consistent Milk Supply

    An optimal fit leads to better breast emptying and helps maintain supply.

📏 Sizing

Most pumps come with a 24 mm flange, but many moms need a smaller size.

Testing with real moms by Jessica Anderson, IBCLC, found that the best way to fit Cushy flanges is to measure the base of the nipple and try flanges 0–4 mm larger, with most moms landing around +2 mm.

Example:
Nipple base measures 17 mm → try 17–21 mm flanges (most moms prefer 19 mm)
