Hello, This is my first post on lactnet since I am new to the list. I have enjoyed the information very much. I do have a response to the discussion regarding milk supply and water intake. During my thesis research, I came across an old reference which may provide support of the practice of "drinking to thirst" vs overhydrating. This reference is: Illingworth, R. S., & Kilpatrick, B. (1953). Lactation and fluid intake in Lancet, volume 2, pg 1175. Hope this is a helpful resource. An example of an oldie but goodie! Cindy Anderson, CNS, MS University of North Dakota
