Hannah Rosin expresses her doubts here in The Atlantic. Here’s the intro:
In certain overachieving circles, breast-feeding is no longer a choice:it’s a no-exceptions requirement, the ultimate badge of responsible parenting. Yet the actual health benefits of breast-feeding are surprisingly thin, far thinner than most popular literature indicates. Is breast-feeding right for every family? Or is it this generation’s vacuum cleaner:an instrument of misery that mostly just keeps women down?
For some women, breast-feeding comes easily. For others, it is more of a struggle. For some it is an impossibility (for medical reasons or otherwise). Information about the benefits of breast-feeding is good. But women shouldn’t torture themselves if they can’t/don’t want to/don’t want to breast-feed for long. Choice is good. Pressure is not.
