I don't know if this is yeast or not. Its white flaky stuff on the tips of my nipples. I can actually rub it off and it goes away. Other than this white stuff, I do not have any other symptons of thrush. And I thought it was a baby's-mouth-to-mommy's-nipple kind of problem anyway I wash & sterilize my pump parts every day, sometimes twice a day and I take a shower cleaning my nipples every day. If this isn't thrush, what is this white stuff?
