This is the story of Mamta Devi who lives in a village in Barmer district. She is 25 years old. Mamta is constantly worried about her 3-year-old son because of his frequent illness. Her son was dull and weak as well. Mamta says, “When I see other children, I feel sorry for my son as he is not as fit and active as others. He always remains dull and doesn’t play with other children.” Mamta was clueless about why her son was dull or fell ill often.
