Data will be collected on anthropometry, feeding practices and hygiene and caring practices etc. The investigators will report the results for 2-sided 5% tests for the primary trial outcome. Secondary analyses will examine each outcome variable (stunting, height-for-age, feeding patterns, and mean nutrient intakes) taking account of the repeated measurements within children by using separate mixed models. The investigators will use linear mixed models for continuous outcomes (e.g. height-for-age Z) and generalized linear mixed models for non-continuous outcomes (e.g. logistic mixed models for binary outcomes e.g. percentage exclusively breastfeeding). It is expected that the publications from this research will have substantial impact on child health and will help with the development of public health nutrition policies for children in South Asia and will be widely cited.
