In the late nineteenth century and the early part of the twentieth century, deaths from infectious diseases in the first years of life were so common that it is not surprising to find so few students of premature birth and so few articles concerning the special needs of low-birth-weight infants. These small infants were not expected to live. In fact, in the 1940s, some authorities thought of birth weights under 3 pounds as incompatible with life, although rare exceptions have always been noted, as in the case of the Dionne quintuplets, each of whom weighed under 3 pounds. Dafoe, who delivered them on May 28, 1934, wrote,"There were no scales small enough to measure accurately the separate weights of the babies, but on May 29 [second day] their combined weight was 13 pounds 6 ounces." They were born about 2 months early. Marie, the smallest, weighed 1 1/2 pounds. Yvonne, the largest, weighed nearly 3 pounds.(Accurate scales arrived on the 6th day.)
