Why shouldn't I use crib bumpers in my baby's sleep area?
Bumper pads and similar products that attach to crib slats or sides are often used with the intent of protecting infants from injury. However, evidence does not support using crib bumpers to prevent injury. In fact, crib bumpers can cause serious injuries or death. Keeping them out of your baby's sleep area is the best way to avoid these dangers.
Before crib safety was regulated, the spacing between the slats of the crib sides could be any width, which posed a danger to infants if they were too wide. Parents and caregivers used padded crib bumpers to protect infants. Now that cribs must meet safety standards, the slats don't pose the same dangers. As a result, the bumpers are no longer needed.
