[blue.cupcakes]

As for sucking in chest tissue, I had the same problem when I went from M to CL domes. The way I was able to fix it is by pumping with only one cup at a time. I'd hold the one cup in place and be sure it wasn't covering my chest tissue and pump (with lots of lotion for a seal). I'd pump for an hour on each breast using the 7:2 method (7 minutes pump & hold, release for 2 minutes and repeat). It's kind of a pain at first, but I've done it for two weeks now and now I can pump with both cups on (with some effort and frustration in the beginning).

Good luck!
