I believe the first recorded American case of the sudden infant death syndrome will be found in Samuel Sewall's diary for February 13, 1686.1 He wrote:
Feb. 13, 1686. Mr. Eyre's little son dyed, well to bed: dyed by them [the parents] in the Bed. It seems there is no Symptom of Over-laying.
In 1863 Dr. David W. Cheever of Boston wrote:2
March 9th; "Sudden Death of an Infant without Known Cause":
An infant, 10 weeks old, apparently in perfect health, suddenly died while sleeping, and after having been asleep one and a half hours.
