This effort came in the form of the aforementioned “Back to Sleep” campaign, which began in the US in 1992, and was remarkably successful. In surveys done in 1992, researchers found that around 70 percent of babies were put to sleep on their stomach.9 By 1996, this figure was only 20 percent. This large change in sleeping position was also accompanied by a decrease in the SIDS rate, further suggesting that sleep position plays a role in SIDS.
