In 1912 she began specifically focusing on children's health issues. Schweitzer collaborated on projects with the U.S. Children's Bureau and surveyed infant mortality in Gary, Indiana. In 1918 she chaired the Indiana chapter of the American Association for the Study and Prevention of Infant Mortality. Schweitzer was also a member of the Indiana State Mental Hygiene Association. In 1919 the Indiana General Assembly authorized and funded the Division of Infant Health and Child Hygiene as a part of Indiana's State Board of Health. Doctor John N. Hurty, director of the State Board of Health, appointed Schweitzer as director of the new division. In her new role Schweitzer spoke to gatherings around the state to encourage improved pediatric care, launched the state's better baby movement, and supervised the Better Baby contests at the Indiana State Fair from 1920 to 1932. Schweitzer's division began with an appropriation of $10,000 and three staff members (a nurse, a chauffeur, and a stenographer). Her initial task was to deliver public health information across the state, especially to remote rural areas. Schweitzer toured Indiana in a truck that included additional equipment to project Magic lantern slides and screen films during her talks to local residents. Schweitzer's work also included managing her staff, authoring articles, and supervising health assessments of young children in all of Indiana's ninety-two counties. A report published in 1920 indicated that Schweitzer's division had collaborated with 476 local, 53 state, and 63 national organizations; hosted conference in 27 Indiana counties; examined 8,000 children; and made presentations at events held in 290 Indiana towns. The significant growth in Schweitzer's division in the early 1920s is attributed to the passage of the Sheppard–Towner Act (1921), which provided federal funding to states that offered maternal and infant-care programs. To become eligible for the matching federal funds, the Indiana General Assembly and Governor Warren T. McCray passed and approved enabling legislation and state funding in 1923. The additional funding tripled the division's initial budget, helped broaden its efforts, expanded its staff, and provided funds to support various studies. In 1925 Schweitzer's staff included four physicians and five registered nurses. By 1926 the division's operating budget was $60,000 and included more than twenty full- and part-time employees. Schweitzer's Division of Infant and Child Hygiene's activities were varied as well as controversial. Schweitzer and her staff provided lectures and demonstrations on infant care and maternal health, sponsored health conferences, presented exhibitions, hosted baby clinics, published and distributed pamphlets and reports, participated in radio programs, and screened films for the public.
