Rachel Hamlet's question jogged my memory about reading a fascinating account of Samoan women who have a very hight fat diet and breastfeed but also have periods very quickly and do NOT trust lactation to provide protection against another pregnancy. K Dettwyler may wish to comment. I recall (dimly) that the article I read was by an anthropologist. I do not recall if the description of breastfeeding was full, although I seem to remember that no solids were being given to teh baby.
