More Mothers Breast-Feed, in First Months at Least - New York Times: "s"
The interesting point is that most moms are starting to breast feed, but I suspect that a much smaller percentage continue to 6 months and beyond, it would be interesting to stratify that continual breast feeders in terms of careers, income, stay at home,etc... as a proxy for infant outcomes, ie more ear infections, more days sick, etc.
