If anyone asked me about it, I would say that the rebuttal is a critique of the original NYT article. As a lactivist, these are the reasons why I know BF is best:

I love this list becuase it provides references to each claim. It seemed that the rebuttal was very defensive and focused only on points where the NYT article fell short. It did not include any additional supportive information for BF. It did not address benefits of reduced maternal breast cancer, it made a blanket statment that BF mom's would "all agree" that they don't have enough time or energy to devote to the rest of the family. I would totally disagree with that. I don't have to mix, steralize, warm, clean, store, and buy my baby's food. I nurse her whenever, where ever, while doing several other things at times

. Part of me thinks the aim of the rebuttal was to be just as "biased" but in the other direction.
It's so amazing to me that so many people feel all this guilt......hmmm, maybe there's a reason, maybe in their hearts, they KNOW that BF is best too!
