The exact cause of SIDS is unknown, but several risk factors have been identified. These include:
Sleeping position: Babies placed on their stomachs or sides to sleep are at higher risk than those placed on their backs. Sleep environment: Soft bedding, overheating, and sharing a bed with parents or siblings can increase the risk. Maternal factors: Smoking, alcohol use, and drug use during pregnancy are associated with a higher risk of SIDS. Premature birth or low birth weight Gender: Boys are slightly more likely to die of SIDS than girls. Family history: Babies with siblings or cousins who died of SIDS are at higher risk.
