4) what causes sudden infant death syndrome also called sids
Sudden infant death syndrome The exact cause of SIDS is unknown.[3] The requirement of a combination of factors including a specific underlying susceptibility, a specific time in development, and an environmental stressor has been proposed.[2][3] These environmental stressors may include sleeping on the stomach or side, overheating, and exposure to tobacco smoke.[3] Accidental suffocation from bed sharing (also known as co-sleeping) or soft objects may also play a role.[2][10] Another risk factor is being born before 39 weeks of gestation.[7] SIDS makes up about 80% of sudden and unexpected infant deaths (SUIDs).[2] Other causes include infections, genetic disorders, and heart problems.[2] While child abuse in the form of intentional suffocation may be misdiagnosed as SIDS, this is believed to make up less than 5% of cases.[2]
