Catherine, about a year ago, Rental Roundup published a succinct summary of savings when infants were breastfed. The summary was based on several peer-reviewed studies, as I recall. I think you would probably need to refine that summary, but it should at least get you started. I moved several months ago, and everything is not filed as elegantly as it should be, but if you truly can't find this, let me know and I'll see if I can give you further information. Feel free to call or e-mail, or both. (I moved from New York State, so I'm really committed to this idea, and hope you can gather a lot of ammunition!)
