During our second month of BFing, my left nip started to lose its pigment just where DS sucks. It was like it peeled off if that makes any sense. So it is now the color of the rest of my skin in the middle and the regular "nipple" color around it, like a bullseye. My right nipple is still its normal nipple color and DS uses both of them but does use the left one a bit more for comfort sucking. Could he be sucking the color off?!?
