How long is it usually for modern humans, 12 months?Researchers were even able to use isotopes to find out when one Neanderthal started weaning her baby. As teeth grow, they lay down layers of enamel. And barium, a molecule children get from breast feeding mothers, builds up in baby teeth until the mother stops nursing. By comparing barium in a Neanderthal tooth with levels in donated present day baby teeth, the scientists were able to find out that the Neanderthal baby had been weaned at about seven months.
http://www.slate.com/articles/news_...how_nursing_worked_in_prehistoric_times_.htmlAnthropologists have studied the weaning customs of hunter gatherer societies, and found significant variation. The !Kung San of the Kalahari desert stop breast-feeding at around 4 or 5 years of age. The Hadza of Tanzania wean about six months earlier than the !Kung. The Aché people of Paraguay wean earlier still, at around 3 years of age. This suggests that human culture and lifestyles have influenced the practice of breast-feeding since the beginning of civilization, although anthropologists still aren’t sure exactly what factors account for the differences.
I found this interesting. How long is it usually for modern humans, 12 months?

Why do some people even so called experts think you should take cow milk?
Who said that originally?

The genetic change that enabled early Europeans to drink milk without getting sick has been mapped to dairying farmers who lived around 7,500 years ago in a region between the central Balkans and central Europe.
