World Breastfeeding Week was first celebrated in 1992 by WABA and is now observed in over 120 countries by UNICEF, WHO and their partners including individuals, organizations, and governments. WABA itself was formed on 14 February 1991 with the goal to re-establish a global breastfeeding culture and provide support for breastfeeding everywhere.
