The purpose of this study is to evaluate the impact of a community-based early childhood development (ECD) program on children's physical and cognitive development. Under the program, targeted communities will be assigned a trained Child Development Agent (CDA) who will have four main tasks and responsibilities: 1) biweekly screening and management (including referral) of acute malnutrition in children; 2) encouragement of caregivers to utilize routine care services for children; 3) screening for symptoms of acute diseases including malaria, diarrhea, and pneumonia and referral for diagnosis and treatment; and 4) organization and mentoring of biweekly caregiver meetings to discuss parenting and promote early childhood cognitive stimulation. The investigators will enroll at baseline around 600 children ages 6 - 12 months and their caregivers, and randomize them at the community-level to receive the ECD program or to remain in the control group. The study period will be one year. At end line, the investigators will collect important indicators of child physical and cognitive development to assess program impact. If the program shows both feasibility and impact, there is the potential to integrate program interventions into existing national community-based health initiatives.
