I too was really puzzled at Peter Hartmann's assertion that babies don't need
more milk as they grow older -- what about growth spurts?  What about
increased kcal needs?  However, ages ago, I read Susan Carlson's ISM from
ILCA -- was reviewing it for the then ISM Coordinator, Lois Arnold -- and she
mentions that although the milk of a mom of a newborn contains about 20
kcal/oz, by the time the baby is 4 months old, it is up to 26 kcal/oz.  Now,
please, someone correct me if I misread it or am not remembering correctly.
 I sent it back after I reviewed it, so don't have it, but did take notes.
 Does anyone else know anything about this?  Susan spoke at an ILCA
conference quite some time ago, and the ISM Module #4 is "The Necessary
Nutrients in the Composition of Human Milk."  If this is as I am remembering
it, it would explain why bf babies don't need a greater volume of milk, if
the kcal of the milk itself increases.  Has anyone else done a study, or
knows of a study that has been done on this?  Generally, when people do
caloric value of milk, they tend to do it early on.  Also, when we do "test
weights" of babies, we tend to do them on relative newborns rather than older
babies; and generally on babies with a problem, rather than on healthy 3 and
4 month olds.  I haven't a clue as to how much volume an average 14 pound
baby takes from the breast.  I don't think we can judge by bottlefeeding, as
I think babies as a rule take more from the bottle (formula OR breastmilk)
than they do from the breast as they can't hang out and have a good time
without eating.  That might also explain why Lisa's milk was "too rich" and
had to be diluted when she donated some, though she didn't say how old her
baby was when she donated.  I can't believe an 8# baby takes 500 ml/24 hours
and a 14 pound baby takes 500 ml/24 hours (or whatever) and both thrive
UNLESS there is a difference in caloric composition.

Maureen -- thoughts?  anyone else?
