In a message dated 97-09-15 12:55:42 EDT, you write: << If the calcium overload seems not to be the answer, before blaming breastmilk for having Too Much Lactose, I'd rather look into baby having Not Enough Lactase, especially if galactosemia, etc, etc has been ruled out. (Can we supplement babies with lactase enzymes in such cases?) >> According to Woolridge, the issue is that the milk is digested too quickly, thus in a sense, not giving the lactase enzyme a chance to "kick in" before it (the lactose) makes its way down the intestinal tract. As Katherine said, there isn't too much lactose (there isn't a difference in the amount of lactose in foremilk or hind milk); however there is an imbalance and quicker digestion which causes fussiness or gassiness in the baby. I've not heard the theory calcium overload; my take on it would be an imbalance in how fast the baby is digesting the milk in the beginning of the feed vs the end of the feed, and how quickly he is able to respond. Which is why, in the face of heavy let-down, some babies do exceptionally well with "lact-aid" drops or some such. Jan
