*Very* interesting....my oldest sister had polio. She was 7 yrs old at the time and had 4 younger siblings, none of whom became ill. Guess who was the only bottle fed baby of the bunch? You got it- my mother was convinced she "didn't have good enough milk" with baby #1. She breastfed the rest of us well into toddlerhood. Chris, RNC Alaska >>> Kathleen G.

Thus, they contracted the disease as young children and young adults because they had no protections early and thus no antibody protection from such exposure." This statement made me sit up and take notice! Do you interpret this as I did? That fewer women were breastfeeding and thus not passing on their own antibodies to the babies, triggering immune response in the babies? Statements about failure to pass antibodies from mother to infant were mentioned SEVERAL times! What particularly struck me about this was that the epidemics in the USA began to increase at the same time that breastfeeding incidence and duration was declining rapidly, particulalry in the middle-class and upper class populations and in the cities. Was this simply coincidental? I don't think so....
