Some parents may be placing their babies at increased risks of dying by putting them to sleep in ways that may be dangerous.

A recent study looked at parents and found that even know the parents knew they were being recorded in the experiment, more than 9 out of 10 babies were placed in sleep environments with non-recommended, potentially hazardous items that increased the risk of suffocation. These items included pillows, loose bedding and stuffed animals.

Here’s what you need to know:

• Resist the temptation of letting your baby sleep in your bed. Babies have been smothered and crushed by adults rolling over on them.

• Place no toys or blankets in a crib with an infant.

• Always remember the saying, “Back to sleep.” Placing babies on their backs is the safest sleeping position.
