(Crib Death; SIDS)


Risk Factors

Risk factors that increase the chance of SIDS include:


A baby that dies of SIDS typically appears healthy. The baby may have had a cold or gastrointestinal infection in the two weeks prior to death. There usually are no warning signs that a baby is about to have SIDS.


Emergency medical personnel should be called as soon as the infant is discovered not breathing. Infant CPR should be started right away. Seek medical care right away even if the baby starts breathing again. The cause of the incident should be fully evaluated. Families may need grief counseling after the death. Some parents find support groups helpful.


There is no way to predict which infants will die of SIDS. Several actions may help you lower your child's risk of SIDS:
