@legendairymilk: Did you know the 24 mm flange size is included with your pump because that was the determined size of a cow nipple? We’ve conducted over 2500 flange sizings with women all over the world and we found that nearly 50% of our clients needed either a 17 or 19 mm flange. The rest of the data showed us: 1% need a 13 mm 10% need a 15 mm 17% need a 21 mm 3% needed the ‘standard’ 24 mm If your flanges are too big or too small, it can lead to pain, clogged ducts, or low milk output—and no one has time for that. 😅 Finding the right fit helps protect your supply and makes pumping way more comfortable (and efficient!)* #flangesizing #exclusivepumping #breastfeeding
