Participants were randomly sampled within 99 clusters selected proportional to population size. Regression models weighted for the survey design, including inverse propensity weights to adjust for differences in sociodemographic characteristics of the cross-sections, were used to assess before/after differences. Alive & Thrive's 12-month intervention engaged fathers through community meetings, religious services, and mobile phone text and voice messages. Mothers received home visits from community health extension workers (CHEWs), which fathers also could attend.

Fathers’ and mothers’ knowledge of the timing of introduction of different foods and meal frequency shifted toward the global recommendations. Fathers’ support for child feeding by providing money for food increased (79% to 90%, P |
