Tom, thanks for the references, I will read them.

I'll have to put this aside for now, though.  There's a lot to cover and
this is a very busy work period for me.

Your reply did address my question, but it's not the question that I really
intended to ask.  My initial remarks had to do with the relationship between
variations in the nutrient content of breast milk and a woman's nutrient
intake, and that's what I meant to get at.

This discussion has increased my interest in the subject and I will pursue
it, when I find the time.  When I have more to report - or to ask - ah'll be
bahk.

Norm
