well i've been noticing for the last month and a bit that i have pale yellow "grains" on/in my nipples... looks kinda gross! after studying this phenomenon for a while i have noticed that they seem to come out of the nipple itself, rather than sitting on the surface and hence have come to the conclusion that it must be a tiny bit of colostrum that leaks out and dries to become these "grains". it must only be a tiny tiny bit though, as nothing comes out when i squeeze gently, and there's been no wet patches on my bra so far. it makes it sound as if i never have a shower or wash, but i do! it just doesn't come off unless i "pick" it off! sorry TMI again....! has anyone else had this? and do you think my colostrum theory is right?
