India suffers from widespread child malnutrition, childcare constraints on maternal employment, and gender education gap. In my dissertation I examine the impact of India's biggest child development program-Integrated Child Development Scheme (ICDS)-on each of these aspects. The program provides various services to children below six years, including supplementary nutrition, preschooling, immunization and health check-ups. In the first paper I look at the" direct''program impact on nutritional status of young children, and in the second and third, I analyze the" indirect''program impact on maternal employment and education of older siblings respectively. For all three papers I use data from recent demographic health survey 2005-6 for India, and for two I also substantiate my results with time use information of mothers and older siblings from another dataset.
