Launched in 2004, the World Breastfeeding Trends Initiative (WBTi) assists countries to assess the status of and benchmark the progress in implementation of the Global Strategy for Infant and Young Child Feeding in a standard way. It is based on the WHO's tool for national assessment of policy and programmes on infant and young child feeding. The WBTi assists countries to measure strengths and weaknesses on the ten parameters of policy and programmes that protect, promote and support optimal infant and young child feeding (IYCF) practices. 

WBTi is a unique web-based data bank having repository of information on policies and programs related to breastfeeding and infant and young child feeding (IYCF) of each country.

It is participatory and brings multiple partners together to do simple and local research, build consensus around gaps and find solutions together. More than 840 organisations including governments and UN took part in 99 countries.
