* On the anniversary of the United States’ entry into the war (the 6th of April 1918), the Children's Bureau, funded with $150,000 from the President's Defense Appropriation, launched a national health education program called “Children’s Year.” This campaign, which was repeated the following year, provided information “on the feeding and care of babies for their mothers and involved the weighing and measuring of some six million infants.” The effects of the campaign were not temporary, as various states set up child hygiene divisions in their public health departments, and the state of California itself established 22 permanent health centres as a result of the bureau's initiative. This program led to the postwar passage of the 1921 Sheppard-Towner Act.[18]
