Just a little personal experience with long-after-weaning nipple discharge... My youngest weaned almost ten years ago. I still have a cheesy white substance which can be expressed from both nipples. Only stimulation is through sex, which may be 1-2x/week on average. Everything seems normal. Both of my children weaned at five years of age.
