However, you should not follow this guideline blindly because the info graphic merely relies on nipple diameter only. In addition to nipple diameter, you should also consider the following factors: Using a ruler or measuring tape, measure the diameter (or distance straight across the middle) of your nipple at the base in millimeters. Do not include your areola. (Tip: Not in a “math” mood? 1 cm = 10 mm.) In this article, I share different ways to measure for the correct flange: Free Flange Size Ruler: Find the Right Fit for Your Pump Flanges! I no longer recommend measuring your nipples - I am finding that a lot of people are overestimating their sizing when basing it just on measuring. But if you do want to measure, make sure you measure your nipple when it is erect ( do not pump first, just stimulate it slightly) and measure about 2-3mm from the base, ie where it meets the areola.

Milk leaks out the bottom of the flange (note that no flange is designed to suction onto the breast and be handsfree)

Another theory for why this new shield improves volume is because its form more closely matches the contour of the breast. When the let-down reflex occurs, the milk ducts in your breast increase in size by 68% to accommodate all the milk flowing through them towards your nipple. 8 This new shape and angle appear to help that milk flow more freely. Jones E, Hilton S. Correctly fitting breast shields are the key to lactation success for pump dependent mothers following preterm delivery. J Neonatal Nurs. 2009;15(1):14-17. https://www.sciencedirect.com/science/article/pii/S135518410800121X Conversely, the breast shield, the part of the pumping system that interacts directly with the breast, has undergone minimal research.

If they’re heavy and harder, that means all the milk hasn’t drained and your flange is possibly too big. and double pumping compared to single pumping, resulted in an approximate 10% improvement in breast drainage.

I didn’t compare from the beginning between using the two sizes. I used size S straight away, and use the maximum comfortable suction level I could.The pump features a closed system so milk cannot get into the tube when used as instructed. Do not clean or rinse the inside of the tubing under any circumstances. The exterior of the tubing can be wiped down with a damp cloth if dirty. Can I store milk in the collection cups between pump sessions? Liquid flange inserts can only be used with the Liquid Flange Kits. These kits come as an option for Pumpables pumps. They are also sold as a stand alone item, but they are single kits. So if you want to double pump you will need two kits. Freestyle™ Hands-free is designed for mums with an active, on-the-go lifestyle. The collection cups fit comfortably inside most nursing bras. Complete discretion, comfort and convenience Jeannine, mum of two, Switzerland, agrees: “The first time I tried the new PersonalFit Flex™ breast shield I put it on and thought, ‘Wow, that just fits!’. With other breast shields I needed two or three attempts of placing it until it sat properly. I put on the oval one and it fitted first time. It’s a pity I didn’t have the oval shield from the beginning – maybe I would have pumped better!” Assessing which factors can influence pumping is essential to understand and improve expression. This study is the first to show that breast shield design influences milk removal dynamics during pumping. The 105° breast shield was non‐inferior compared to the standard 90° breast shield in all primary and secondary outcomes, and was superior for PAMR, expressed milk volume, and was more comfortable. Expressing with the 105° breast shield was therefore more effective, efficient and comfortable than with the standard 90° breast shield.
