Sudden infant death syndrome (SIDS) is the leading cause of death in the first year of life.Footnote 1 Although there is no known cause for SIDS, research has identified smoking as one of the major preventable risk factors.Footnote 2
Infant bed sharing increases the risk of SIDS, particularly among infants of mothers who smoke.Footnote 8
Some of the chemicals in tobacco smokeFootnote 9,Footnote 10 alter the development of an infant's brain and the lungs. This in turn affects how an infant breathes and may be responsible for SIDS.Footnote 1,Footnote 5
Women refraining from smoking while pregnant will reduce the risk of death among their newborns during the first 7 days.Footnote 2
