Dr. Miriam Labbock, from Institute for Reproductive Health, Georgetwon University published an article in the Academy of Breastfeeding Medicine newsletter. She stated "Using the disease-based model and illness reduction that could be expected from full breastfeeding for 12 week, it is estimated that the US would save $2.16 billion annually." I do not know if she has done further analysis of the data, or if has been published elsewhere. If anyone knows if it has been published please send me the reference.
