Interesting.... I am born same year, Germany, my mom breast fed me for a year and she was told breast milk is best (though supplemented with cereals starting at 6 weeks)- I was pudgy big time. My husband's mom, same year, same country, was tested and told her breast milk was not good. I never was able to find out what they tested - she was astonished that they don't test every woman's milk if it is any good. My best guess is DDT, a pesticide they found at one point in breast milk - but I have really no idea!
