This is owing to the fact that information on breastfeeding is available only for children who are born within the five-year interval before the survey, and the logit model forces us to drop all observations that are not fully at risk—in this case, all children less than five years of age and alive at the time of the survey. For control purposes, we also run a separate estimation for under-five mortality (excluding breastfeeding as a determinant). The results broadly confirm this view and are reported in the annex.
