SIDS - SUDI - SUIDS. Which is the right term?

SIDS - Sudden infant death syndrome

SUDI - Sudden unexpected death in infancy

SUIDS - Sudden unexpected infant death syndrome


Sorry if this is an odd question, basically they said SUDI on the news tonight which I hadn't heard of, but our ciggy packets have SIDS which I always thought it was.

Then after a google I get another one SUIDS.

Any medical people know what it should be called?
