Sudden Unexpected Death in Infancy (SUDI), incorporating SIDS, claims the lives of approximately 100 babies a year in Australia alone…

…that’s 100 innocent babies, with dreams and aspirations lay right before them, tragically gone in an instant.

Sudden Infant Death Syndrome, or SIDS, is the sudden unexplained death of a child less than one year of age.

The usual medical term is ‘Sudden Unexpected Death in Infancy’ (SUDI) or Sudden Unexpected Death in Childhood (SUDC), if the baby was over 12 months old.

If after thorough autopsy there is no medical explanation for the cause of death, such as an infection or disorder, these deaths that remain unexplained will be registered as ‘Sudden Infant Death Syndrome’ (SIDS) or SUDC in a child over 12 months. The term “unascertained” may also be used in some cases.

The exact cause of SIDS is unknown.

Why does SIDS happen?

No one knows, but we’re doing our best to find out.

The requirement of a combination of factors including a specific underlying susceptibility, a specific time in development, and an environmental stressor has been proposed.

These environmental stressors may include sleeping on the stomach or side, overheating, and exposure to tobacco smoke.

SIDS has been known to occur in a range of sleeping environments, such as the cot, bassinet, car seat, pram and even in people’s arms. SIDS has been known to occur at any time of the day or night.

Some babies may have a problem with the part of brain that controls breathing and waking. These babies don’t respond if their breathing is slightly restricted. We know this through evidence based research.

About 90% of SIDS cases happen in the first six months, with the risk falling as your baby grows older.
