Campaign

In 1985 Davies reported that in Hong Kong, where the common Chinese habit was for supine infant sleep position (face up), SIDS was a rare problem.^[4] In 1987 the Netherlands started a campaign advising parents to place their newborn infants to sleep on their backs (supine position) instead of their stomachs (prone position).^[5] This was followed by infant supine sleep position campaigns in the United Kingdom, New Zealand, and Australia in 1991, the U.S. and Sweden in 1992, and Canada in 1993.^[5][6]
