Hello, Lisa.
       I don't know about upper limit, scientifically.  But a mother I have
worked with twice so far (she just had her third two days ago, so I am
interested to see what happens this time) has had *plenty* of milk each time.  With
her second baby, when the milk came in, she produced 60 ounces/day *beyond* what
her baby needed.  (No, that's not a typo--she really produced 60 extra
ounces.)  Baby was just miserable, and we could not downregulate her supply with the
tricks I knew at the time, so she pumped and bottle-fed baby, which kept his
digestive tract much happier.  By the time he was 4 months old, she was "down"
to producing 14 oz/day more than her baby needed.
       I have learned quite a few more techniques for possibly reducing
supply from all you folks on Lactnet.  I am curious to see if she overproduces to
the same extent this time around.  If so, I plan to offer some of the
suggestions I've learned here!
