While a clear cause for SIDS has never been established, it's believed to be linked to an inability to gasp.
"Sudden Infant Death Syndrome is such a distressing tragedy for families," study author Stella Lee of the Geisel School of Medicine at Dartmouth, New Hampshire said.

There are a number of risk factors associated with cot death.
Parents are urged not to let babies sleep anywhere except in a cot on their back and without any blankets or loose bedding that could lead to suffocation.
