Many parents swear by swaddling because it can help newborns stop crying.
Swaddling infants may also reduce the risk of sudden infant death syndrome, because it encourages parents to lay their babies on their backs to sleep.
Unfortunately, loose blankets can be a suffocation risk if babies wiggle out of a swaddle that's done incorrectly.
Now more than 700 hospitals nationwide have ditched the typical swaddle in favor of sleep sacks.
They're wearable blankets that put babies in a cocoon-like cuddle, but easily zip up without covering the baby's face.
Bill Schmid is the founder of Halo Innovations, the company that makes sleep sacks.
He says giving new parents proper visuals of a safe swaddle and crib is important when they're exhausted and overloaded with information on how to care for a new baby.
"They may hear something and they don't remember it, but they tend to remember what they see, which is why it's so critically important for hospitals to be modeling what they're preaching," he says.
The newborn nurses at University Hospitals Case Medical Center in Cleveland took it a step further, ridding their cribs of everything that could possibly pose a suffocation risk.
Nurse Debbie Smith and her staff tout the importance of safe sleeping.
"You want the baby to sleep in an environment that has literally nothing but the baby swaddled in a sleep sack and a bare naked crib," she says.
Good advice, and easy to remember for new parents wrapped up in their new bundle of joy.
