Medela's "breast pumps," based on years of research, support breastfeeding. [Easy operation with 4 buttons] A standard model of electric breast pumps that is easy and efficient. The electric breast pump automatically creates the optimal rhythm and pressure, so you can pump efficiently just by placing it on your breast. You can adjust the pressure and mode with just four buttons, making it easy to operate even while pumping. [Compact and lightweight design for daily use] During the breastfeeding period, you may encounter problems such as latching issues, breast infections, and nipple pain, which can make direct breastfeeding difficult.
