Current research now suggests that if babies sleep on their backs, the chance of SIDS is much less. No reason has been given for this finding. And since traditionally babies sleep on their stomach, this counter measure still raises eyebrows. Many people believe if the baby sleeps on their back they will spit up and choke to death but doctors have found no rise in the number of choking deaths due to sleep position. If your baby cannot sleep on its back due to a medical condition, researchers advise sleeping on the side as long as the lower arm is out to prevent the baby from rolling onto its stomach.
Crib bedding is also important.
Remove anything that is too fluffy that may hinder breathing ability. Keep the room warm but not too warm. And be sure to check your baby constantly throughout the night. But don't become paranoid about it. Simply stay alert and keep watch over them.
