- If you should still fall between our sizes, we recommend sizing down.
- If you measure larger than 25mm, we recommend applying a baby-safe lubricant to your nipple because it may rub slightly and then evaluating the fit and comfort of our 27mm flange.
If after your first few pump sessions you feel uncomfortable or don’t get the milk volume you expected, we recommend experimenting with a different size until you get it just right.
Our flanges have been tested for a use-life of 90 days. This means you should replace your flanges as well as the FlexTubes™ and containers every 90 days or if you notice signs of wear.
