Description
It's not known why some babies die suddenly and for no apparent reason from sudden infant death syndrome (SIDS), or cot death.
Experts do know placing a baby to sleep on their back reduces the risk, and exposing a baby to cigarette smoke or allowing them to overheat increases the risk.
It's also known there's an association between sleeping with your baby on a bed, sofa or chair (co-sleeping) and SIDS.
SIDS is rare, so do not let worrying about it stop you from enjoying your baby's first few months.
