I have never heard of mother's milk having or causing too much calcium. I would look for an outside source, like is anyone else feeding the baby anything? Is the baby ever out of the mother's care? Could the remote possibility exist that the mother is giving the baby something covertly to cause illness (Munchausen by proxy - not sure I'm spelling this exactly?) What about some sort of metabolic disease causing this derangement? or parathyroid situation? renal? Hope the neos will give us the differential diagnoses.
