Breastfeedling just like the pregnancy drains the body of nutrients - some women are so under-nourished that they actually feel the drain. Again - supplements and very good food is the solution.
Breast milk has so many positive effects on child-development, that it cannot even be compared to any kind of substitute. Recently they acknowledged that breast-milk has even cancer-fighting and highly regenerative properties. 1-2 years should be the minimum for every mother - though not exclusive in the end of course.
In many countries they started up breast-milk-banks where women with surplus can deposit theirs for other women who are lacking. Even conventional medicine had to backtrack and acknowledge that formula lets you barely survive - but nevermind building a stronger immune system, higher IQ and better mental faculties.
