This set of case studies documents country experiences in implementing the Baby-friendly Hospital Initiative (BFHI) over the first 25 years of its existence. These case studies are testimony to the diversity in BFHI implementation. While several countries have been able to bring the BFHI to a national scale, in other countries the coverage has remained more confined. Coordination mechanisms and operational modalities also vary from country to country. The compendium is designed to reflect a range of country experiences. While it is difficult to generalize, some key commonalities can be extracted from the case studies.
