The BUNDLE study will examine the effects of a 7-month nutrition and caregiving intervention for female and male caregivers delivered by trained adult community facilitators in rural communities across Liberia. The study will use a four-arm 2x2 factorial cluster randomized design to test the effectiveness of the interventions on primary outcomes of child cognitive, language, motor, and socio-emotional development. In this study, 2240 children aged 6 to 30 months will be recruited from 160 rural communities randomized to a comparison arm or one of the three intervention arms. The comparison arm will receive the local standard of care. Three intervention arms will also receive either a responsive stimulation intervention with female and male caregivers, provision of eggs and dried fish accompanied by nutrition education, or responsive stimulation + provision of eggs and dried fish. We hypothesize that child development will be improved in all intervention arms compared to the comparison arm and in the combined intervention arm compared to the single intervention arms.
