I have a question, or series of questions, actually.

   It is my understanding that as the baby nurses, the foremilk comes first,
and then becomes a mix of fore and hind, and then becomes just the hind
milk.  That is why we want a baby to finish one side before going to the
other, and why we encourage moms with oversupply to feed just on one
side at a feeding (as well as to help reduce the supply over time).

So if a baby is stopping and starting, over the period of an hour, say, on
just one side, doesn't he keep getting just foremilk?  Or does he keep
getting a blend? Does it depend on the length of the breaks he takes? Like
with every three to four minutes, he might be getting the continuum over an
hour;  but with every 20 minutes, he keeps getting new supplies of skim or
skim and  whole without ever getting to the cream?

What is the current scientific knowledge that supports our practice?  Or is
it more theoretical and experiential at this point?

The babies of one area in Africa are reported to nurse for 2-3 minutes, every
 15 minutes all day long.  They are kept constantly near the breast,  and
this is the pattern that seems to develop.  (I have no idea how often moms
switch baby's position from one breast to the other.)  Yet they thrive.  Why?
