When the cause of death remains unexplained after. investigation, the death is registered as SIDS. A baby's death is not considered SIDS. when a specific cause is found. It is thought that many SIDS deaths are caused by a breathing failure, but how or. why this failure occurs is not known. Possible causes include suffocation, overheating and choking, but none of these has been proven. Further research is. taking place into the causes of SIDS. Babies who die from SIDS die painlessly in their sleep, and there are no signs of. struggling - the baby is often found in the same position as when he or she was put. down to sleep.
