<< Lactose does not vary from the beginning of a feed to the end of a feed. In the absence of true lactose intolerance (very rare) Green stools may be a result of rapid gut emptying from a strong MER or sometimes viral induced damage of the intestinal brush border and, as you say, are temporary and of no consequence. >> But it is MY understanding that what IS important is that the higher fat content of hindmilk will slow gut motility, and thus the rate at which the lactose moves through the small intestine. When it moves through more slowly, it is better digested and absorbed. When it moves through more quickly, more undigested lactose ends up in the large intestine, where it draws water back INTO the stool, and normal bacteria there can use it as fuel, producing "gas". Also, the green color is bile that doesn't have the chance to be reabsorbed because it moved through too fast...whatever the reason.
