I have been exclusively breastfeeding for 10 and a half months. Over 2 months ago I noticed this white patch thing on my left nipple. This white patch doesn't go away when I shower or feed like I would think dry skin would. It doesn't hurt or itch ever so I haven't paid much mind to it. But since I've had it for so long I figured i would come on here and see if any of you ladies have gone thru this or any advice on what I should do.
