Heather Welford Neil wrote "I do think the whole issue is interesting, nevertheless, from a research point of view rather than a therapeutic one. For instance, the Woolridge et al work showing how variable intake/calories/time can be depended on some form of accurate (not guessing) assessment, and perversely, papers of that time show just how pointless test weighing and timing can be." I agree. We clinical folks can refer to the work done by the researchers when we teach about breastfeeding---whether teaching other clinicians or teaching parents. Otherwise the infant feeding model that is staring everyone in the face is the ubiquitous bottle, and people make assumptions about Normal Infant Feeding (breastfeeding) based on what they see all around them. Thank goodness for the work of people clever enough to snoop inside babies' mouths and moms' breasts and figure out just how that sandwich mom ate for lunch turns into the milk her baby takes at dinner-time. "Still interested in any response to my post about Deuterium Kinetics as a way of measuring intake, BTW." I don't pretend to understand it, but what little I know is from the paper "Methods for the measurement of milk volume intake of the breast-fed infant" by Woolridge, Butte, Dewey, Ferris, Garza, and Keller in "Human lactation: milk components and methodologies," edited by Jensen and Neville, Plenum Press, 1985. This is volume I of the three "Human Lactation" books that Plenum put out in the late '80s. I think another reference to the method is found in an address by RG Whitehead that I mentioned in a long post from 9 April 1996, Subject: How much milk? You could check the archives.
