Wrote an article about flats.
Also Hubby sent me an article about extended breastfeeding. I about fell off the couch. He's not one to be totally on board with everything I do. He likes to use disposable diapers and he keeps wanting me to wean HB. So this was nice.
To answer this question Yale University anthropologist Clellan Stearns Ford utilized the largest historical collection of anthropological data available, the Human Relations Area Files, and analyzed the weaning age of 64 non-Western “traditional” societies–small-scale horticultural and hunter-gatherer populations. His analysis (see Figure 1 below) determined that the average age of weaning is approximately three years old, just as Harvey and Clutton-Brock’s data predicted. Furthermore, because these traditional societies are dispersed throughout the globe and have no contact with one another (or often anyone except the visiting anthropologists) these societies offer a broad enough sample size to avoid the problem of confirmation bias.Also
For example, research carried out in Burkina Faso by epidemiologist Simon Cousins for the Bulletin of the World Health Organization and in Washington, DC by Dr. Kathleen M. Buckley for the Journal of Human Lactation, both showed that extended breastfeeding until three years old resulted in lower rates of malnutrition compared to those who were not breastfed as long. Longer duration of breastfeeding has also been shown to significantly improve a child’s immune response to infectious disease. Writing in the British Medical Journal, Kåre Mølbak and colleagues at the University of Copenhagen analyzed the incidence of diarrhea in weaned and partially breastfed children in the West African Republic of Guinea-Bissau. They determined that not only did breastfed children get sick less often than weaned children, but those who continued partial breastfeeding up until the age of three had the lowest rate of infection.(Emphasis mine)
