I have two children...both nursed until they self weaned at 18 months, likely due to my being pregnant. My youngest has started asking for "milk" again and I offered to him knowing that my milk in quantity is long gone. He only suckles for a a few seconds and is done and maybe just once a week or so. No biggie except for the pain it causes me! Today, though, as I was trying to get a little bit out, or see if there was any, my nipple expressed dark green, like forest colored, liquid from some of the milk holes and then greenish yellow like colostrum tends to be in the early days after birth and some was clear. It was very strange. I have never had that before. Anyone else??? It's only on one side. I can't get anything from the other side. I don't know if I am concerned I just think it's weird!
