Does anyone know whether Miriam Labbok has done any further work on breastfeeding definitions since her 1990 article? Our local health unit wants to start collecting statistics on breastfeeding duration and I thought some definitions of breastfeeding would be a good place to start to ensure consistent data collection. I have the 1990 article but want to be sure there isn't anything further on this. Other suggestions on articles/definitions would be welcomed, as well.
