Previously used a pump occasionally (the Lansinoh electric) with first DC and would like to express this time around too. I purchased a recommended cheaper double pump off amazon which felt like it was pinching when I tried it. I then ordered a Lansinoh double electric as I had used this previously with no problems and it came with standard and large shield sizes but this hasn’t helped. It still feels like it’s pinching regardless of the size used. I have googled and the flange isn’t too small, if anything even the small pulls quite a bit of the areola into the pump but not sure they do a smaller size or insert that I could use? Any advice please as I can’t just keep purchasing things in the hope it might work.
