This project provides sustainable home-based child stimulation training and child nutrition to vulnerable adolescent mothers, using a peer-led social marketing model championed by adolescent mothers who will be trained on the use of social marketing that is popular with adolescents. Appropriate child stimulation activities will be designed and shared on social networks, and toys will be bundled with infant food and sold to the mothers during home visits. Primary outcomes anticipated include improved cognitive development in 3,600 children, along with improved socio-economic status of the adolescent mothers.
