Hi Dana. I would refer you to the work of Dr. Ruth Lawrence, in her book BF: A Guide for the Medical Profession, 2000, as a reference for the questions about breastmilk composition that you pose. Having this reference is a good idea for all professionals. You could also do a MedLine search for this information as well, which would turn up recent research articles. The National Library of Medicine hosts such a search service, and there are others. FYI. Thanks. Kathleen Kathleen B. Bruce, BSN, IBCLC co-owner Lactnet, Indep.
