A study of the skeletons of nine children of the prominent Italian Renaissance-era Medici family found that they had rickets, a vitamin D deficiency that causes soft and deformed bones. The study reveals that, customary to the 16th century, the Medici children were heavily swaddled as infants, would not have spent adequate time outside in the sun to absorb vitamin D and were not weaned until about age 2.
