What does sids (sudden infant death syndrome) have to do with smoking?

If mom smoked while pregnant, the toxins likely affect baby's respiratory center in brain and make it less mature. After birth, the poisons and toxins in the smoke, which can stick to your clothes, may affect the "switch" to tell baby to breath or affect the heartbeat.
