And what are your organs doing during this time? Are they not cleansing everything "Before" it gets to the breast? The human body is not stupid. If this child is not dependent on the breast milk and getting his/her food by regular eating, then I say the breast milk can do no more harm than the water he/she drinks or the air that he/she breathes. Mothers milk is a natural and the body looks after the young. It's mother nature.
