I know there have been ways of feeding babies who couldn't for whatever reason be fed by their mothers or wet nursed throughout history. But there must only have been 2, or at the most 3, generations of mothers who had a genuine choice as to how to feed their babies. I think it's amazing that such a fundamental change in how we raise our babies has happened so quickly - in 50 years we've gone from automatically (because no choice) breast feeding to a more or less 50/50 splint between bf and ff. Are there any books looking at how/why this happened?
