Sudden Infant Death Syndrome is the leading cause of death for babies under a year old with most SIDS deaths occurring between the ages of 2 and 4 months.
The deaths come without warning, and for a long time without any known cause. Parents these days are told to put their newborn babies to sleep on their backs to reduce the risk for SIDS. The "Back To Sleep" campaign has been successful, reducing the number of crib deaths by about half since it began in the early 90's.
Still, thousands of seemingly healthy babies die in their sleep each year.
"You cannot tell a living baby is going to die of SIDS that night. There's no marker," said Dr. Hannah Kinney of Children's Hospital Boston.
But now doctors at Children's Hospital Boston have uncovered a big clue leading them to a likely cause for SIDS.
"We've come to focus on serotonin," said Dr. Kinney.
