The Medela PersonalFit Flex™ breast shield was developed in collaboration with researchers and breastfeeding mothers to make pumping as comfortable and convenient as possible.
The breast shield has a soft edge, a 105° opening angle and an oval shape (which can be rotated 360°) for more comfortable pumping and optimized milk production. The shape of your breasts is unique and can change during breastfeeding. With this breast shield, you can easily adjust the fit of your breast pump to make it easier to find the most comfortable and effective pumping position.
How to find the right size Medela breast pump for you:
Pumping shouldn't hurt. To make it as comfortable and effective as possible, Medela offers five breast shield sizes. This guide will help you determine the best size for you based on your nipple diameter.
Step 1: Using a ruler or measuring tape, measure the diameter of the nipple at the base (center) in millimeters. Do not include the areola.
Step 2: Determine your Medela breast shield size based on your measurements.
Example: If your nipple size is 16 mm in diameter, the recommended Medela breast shield size is 21 mm.
Nipple diameter (Ø mm) maximum 17 mm = Breast pad size 21 mm
Nipple diameter (Ø mm) maximum 20 mm = Breast pad size 24 mm
Nipple diameter (Ø mm) maximum 23 mm = Breast pad size 27 mm
Nipple diameter (Ø mm) maximum 26 mm = Breast pad size 30 mm
Nipple diameter (Ø mm) maximum 32 mm = Breast pad size 36 mm
