Medela Swing Flex Electric Breast Pump - Compact Design - with PersonalFit Flex Breast Shields and M

The item was used only two times and the warranty bill is still valid till the end of April 2025. Medela SwingFlex single electric breast pump is infused with patented and research-based 2-Phase Expression Technology. Through research, Medela has learned that there are two distinct phases of how babies breastfeed. The first phase, known as stimulation phase is when the baby first goes to the breast and sucks fast to initiate the milk flow. The second phase of expression occurs after milk flow or œlet-down begins. During this phase, baby breastfeeds at a slower suck rate for continued milk flow.
