In this mixed method study, we described the multi factors to maintain child health among malnourished children living in the nomadic tribe of Sikar, Rajasthan. Nomadic tribes form 15% of the Indian population. Unlike SCs and STs, nomadic tribes are not part of the Indian census. We determined how WASH practices and mothers' knowledge attitude practices are related to child health. We collected data from 11 mothers of 0-5-year-old children living in the Basti. Structured questionnaires and in-depth interviews were conducted to obtain information on sociodemographic profiles, WASH practices, and information on child health. Our finding suggests that empowering mothers with knowledge related to WASH practices, government health schemes, and government policies is needed to maintain the health status of their children. In addition, the finding suggests that examining comprehensive nutrition and other health practices is critical in maintaining the child's optimum health, particularly in vulnerable populations such as nomadic tribe settings. There are very few studies on the nomadic tribes of India, and they are untouched by researchers. This study will bring facts for consideration for better health of their children. Among nomadic tribes, there is double burden of undernutrition and poor sanitation facility. Therefore, a diverse set of intervention may be required to improve knowledge of mother which will facilitate good health of their child.
