The Baby-friendly Hospital Initiative (BFHI) is a global effort launched by WHO and UNICEF to implement practices that protect, promote and support breastfeeding. It was launched in 1991 in response to the Innocenti Declaration. The global BFHI materials have been revised, updated and expanded for integrated care. The materials reflect new research and experience, reinforce the International Code of Marketing of Breast-milk Substitutes, support mothers who are not breastfeeding, provide modules on HIV and infant feeding and mother-friendly care, and give more guidance for monitoring and reassessment.
