First time as a nursing mom, i first held the flanges to my pump which made pumping take for. Ever. On YouTube i have seen a pumping mom suggest cutting round holes into shelf camis which i tried but it was a pain undressing and changing into the cami wheneveri had to pump, and me n my husband would always have a laugh because i looked funny in it. With all the good reviews, i decided to try this (in black). Now that I'm back to work, pumping has become less tedious of a task. I just lift my shirt up and unsnap my nursing bra, put this on and I'm ready to pump.  I have the bella band on too just so i don't feel so bare. I have also purchased the all in one cami that unsnaps for nursing and has the opening for pumping but i still prefer this over it.
