Parents, for years you have been urged to place babies on their backs to sleep.
But the protective measures against sudden infant death syndrome don't stop there.
Dr. Skyler Kalady with the Cleveland Clinic Children's Hospital. "In your home, please no smoking, that is very concerning. If you're able to breastfeed, that's protective. Children, once they've established breastfeeding, using a pacifier at night is protective"
The sleep environment is also critical to a reduced risk for SIDS.
Doctors say your baby should be in his own crib or bassinet and it should be bare.
Bumpers, blankets, pillows, and even stuffed animals should not be placed in the crib, they're all potential hazards.
Soft bedding should also be avoided.
