J'y! I'm A 65 Hrs Old Grandmother And I Still

J'y! I'm a 65 hrs old Grandmother And i still produce milk, Can feel it come up every month or so. The color is White And green. I just noticed that a drop was the Color of ink. I asked herbalists ( I am one) , nurses, midwives, Drs I read that grandmothers in tribal times were used to breastfeed newborns when the mothers were killed. Not as good as a young woman but good enough to feed a child. The lactation doesn't worry me but the " ink" colour does. Any answers for me? Thank you
