Between 2006 and 2008 we carried out a cluster randomized study (PROMISE-EBF) to establish the effect of individual home based peer counselling on exclusive breast feeding (EBF). The results, published in the Lancet in 2011 were remarkable(Tylleskar T, et al). The PROMISE-EBF trial which compared mothers in the intervention arm that were offered at least 5 peer-visits promoting EBF to mothers in the control arm, that received the standard of care showed a doubling in the prevalence of EBF in the intervention arm. Community-based peer counsellors increased the EBF rate in Uganda and Burkina Faso from about 40% to 80%.
