Has anyone used the Willow breast pump? I have used the Spectra S2 and the Freemie in the past with my daughter. The Freemie had terrible suction loss and did not work at all for me. I had an undersupply so lacking good suction was disastrous for my alrdady low supply. We are pregnant again, and I am really interested in the Willow. Handsfree would be amazing, especially for when I have to return to work. It was so hard to get time away to pump last time that after 2 months of going back to work, my supply all but dried up. I would love to hear about anyone's experience with the Willow. Being able to pump at my desk and noy having to be chained to an outlet would be amazing.
