I can't do compression/massage while pumping without breaking suction - hence - the farting noise as the flange slips away from my boob mid-pump. Am I just dumb? What am I missing here?
Wheee!

Re: How do you do compression/massage while pumping - without that farting noise?
I had that problem until I went up a flange size, Lucy, which turned out to be waaaaaaay more comfortable for me anyway.
