• Maternal Depression

Interventions

BEHAVIORAL

Water quality

Hardware: Free supplies chlorine tablets (Aquatabs; NaDCC) and a safe storage vessel to treat and store drinking water. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on the treatment of all drinking water for children \< 36 months of age.

BEHAVIORAL

Sanitation

Hardware: Free child potties, sani-scoop hoes to remove feces from household environments, latrine upgrades to a dual pit latrine Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on the use of latrines for defecation and the removal of human and animal feces from the compound.

BEHAVIORAL

Hand washing

Hardware: Hand washing stations, soapy water bottles located at hand washing locations, detergent soap to supply soapy water bottles. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on hand washing with soap at critical times around food preparation, defecation, and contact with feces.

BEHAVIORAL

Water quality, Sanitation, Hand washing (Combined WASH)

Hardware: Free supplies Aquatabs; (NaDCC) and a safe storage vessel to treat and store drinking water. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on the treatment of drinking water for children \< 36 months. Hardware: Free child potties, sani-scoop hoes to remove feces from household environments, latrine upgrades to a dual pit latrine. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on the use of latrines for defecation and the removal of human and animal feces from the compound. Hardware: Hand washing stations, soapy water bottles, detergent soap to supply soapy water bottles. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages that focus on hand washing with soap at critical times as food preparation, defecation, and contact with feces.

BEHAVIORAL

Nutrition

Supplement: Lipid-based Nutrient Supplement (LNS) delivered daily from ages 6 to 24 months. Promotion: Local promoters will visit study compounds at least monthly to deliver behavior change messages modeled on those recommended in the Guiding Principles for Complementary Feeding of the Breastfed Child and the recent UNICEF Program Guide for Infant and Young Child Feeding Practices.General messages will include (1) practice exclusive breastfeeding from birth to 6 months of age and introduce complementary foods at 6 months of age while continuing to breastfeed; (2) continue breast feeding as you did before receiving LNS; (3) provide your child micronutrient-rich foods such as meat, fish, eggs, and vitamin A rich fruits and vegetables; and (4) feed your child at least 2-3 times per day when 6-8 months old and 3-4 times per day when 9-24 months old.

BEHAVIORAL
