According to USA Today, car seats can be deadly for babies when being used incorrectly.

Investigating infant deaths in sitting devices, such as car seats and strollers, researchers found that more than two thirds occurred while in car seats.  In those cases, parents were using the car seats as directed less than 10 percent of the time.

The study, published Monday in the journal Pediatrics, examined 11,779 sleep related deaths from 2004-2014.

Car seats aren't as safe as a crib or bassinet when the child is out of the car and sleeping.  There's a lack of awareness, according to study author Dr. Jeffrey Colvin.

More than half of the deaths in car seats occurred when the child was at home and under the supervision of a parent.
