When can I stop worrying about SIDS (sudden infant death syndrome)?

Hi, Most SIDS deaths occur when in babies between 1 month and 4 months of age, and the majority (90%) of SIDS deaths occur before a baby reaches 6 months of age. However SIDS deaths can occur anytime during a baby's first year. SIDS is a sudden and silent medical disorder that can happen to an infant who seems healthy.
