Medela which size breast shield

All electric breast pumps come with at least two flanges, which are usually a standard size of 24 to 27 millimeters mm. Using the wrong breast shield size may not seem that important, but it can cause significant problems. Having a breast shield size that is too big or too small can cause pain in your breasts as well as cause you to not pump as much milk as you should, which can lead to blocked milk ducts.

How to measure your nipples Courtesy Medela. A breast pump flange, also known as a breast shield , is the plastic piece that fits directly over your nipple to form a seal around the areola. This creates a vacuum seal that gently draws your nipple into the flange tunnel for milk extraction.

Having the wrong size flange can impact milk supply and lead to soreness or clogged milk ducts. Leah DeShay, IBCLC , explains that oftentimes when mothers experience an issue with breast pump suction, it's actually because they need a different flange size.

Having correct contact with the nipple and breast tissue is incredibly important for adequate suction and milk production. For first-time pumpers, seeing a lactation specialist can be helpful in determining the correct flange size for your nipple size as well as areola density and fullness, and can make a big difference in your pumping experience.

Use a measuring tape to determine the diameter of your nipple. The standard flange size is often 24mm, but you may need to select smaller or larger flanges based on your measurement. There are five main pump flange sizes but keep in mind not all are offered with every breast pump, so make sure to check your manual for what is included with your pump.

Also, be sure to measure both of your breasts in case you need two different sizes. Click here to download the breast shield sizing handout [PDF]. Professional Resources. Share this content.

A note about nipples: Be sure to understand the difference between the nipple and areola. Testing Breast Shield Size To confirm which size breast shield is the best fit, watch the nipple movement during pumping. Start with the 24 mm breast shields or the size determined by measuring the nipples. Center the nipple and gently hold the breast shield against the breast.
