Re: Medela Swing- ?
You are suppose to wash the yellow piece and the white membrane after every use. I thought I could get away with not washing every time, but ended up having the same problems as you describe. Then I started washing more frequently (not after every use) and the problem was solved. I still had to replace the white membrane quite often, but not the yellow piece so much. Now I have a Medela Freestyle and I still loose suction if I don't wash the membrane & pump parts regularly enough, but I haven't had to replace anything with it yet.
