I have followed the various posts on this track with interest.  My small contribution is to raise the issue of relactation.  I believe there is a valid point to make for describing a baby who has returned to nothing-but-the-breast as "exclusively" breastfeeding, especially where this continues for an appreciable time (not just a week or so or a few days).
    Perhaps we need improved definitions, or more categories.  The definition of *exclusive* BF that means nothing-but-the-breast from *birth* might better be described as "exclusive BF (*never* received other foods)".  Babies who have returned to total breastfeeding, after being fully artificially-fed or supplemented (mixed feeding), and who have had nothing-but-the-breast for a month or more, are surely a special category, and one worth separating out and studying.
   My elder daughter, born Feb 1965, is a case in point (relactated and then exclusively BF for one-and-a-half months till solids introduced at 4 months).  However, she is one example of many.
