We use data from three waves of India National Family Health Survey to explore the relationship between the month of birth and the health outcomes of young children in India. We find that children born during the monsoon months have lower anthropometric scores compared to children born during the fall-winter months. We propose and test hypotheses that could explain such a correlation. Our results emphasize the importance of seasonal variations in environmental conditions at the time of birth in determining health outcomes of young children in India. Policy interventions that affect these conditions could effectively impact the health and achievements of these children, in a manner similar to nutrition and micronutrient supplementation programs.
