The LINKAGES Project is intended to improve breastfeeding and related complementary feeding and maternal dietary practices. The project, in consultation with technical experts and program managers, identified a set of recommended feeding and dietary practices intended to break the cycle of poor health and nutrition that passes from generation to generation. This booklet presents the technical justification for the recommendations, focusing on: a summary of recommended feeding and dietary practices for infants age 0-6 months (e.g., initiate breastfeeding within about 1 hour of birth, establish good breastfeeding skills, and breastfeed exclusively); breastfed children age 6-24 months (continue frequent, on-demand breastfeeding to 24 months and beyond, introduce complementary food around age 6 months, increase food quantity as the child ages while maintaining frequent breastfeeding, practice active feeding, and practice good hygiene and proper food handling); and adolescent girls (age 10-19 years) and women of reproductive age (e.g., increase food intake as needed, diversify the diet to improve quality and micronutrient intake, use iodized salt, and allow adequate tie between the cessation of lactation and the next pregnancy to replace and build up energy and micronutrient reserves).
