Several different cribs have been recalled because of the risk of suffocation. A gap can form that can lead to the baby becoming trapped and then suffocating. The deaths associated with this have been because the drop-down bar was installed upside down. There were some reported incidents when the cribs were installed properly. The Consumer Product Safety Commission and Simplicity has more information about the crib recalls and what you should do if your baby is sleeping in a recalled crib.
Some of the cribs are under the Graco label, so if you have a Graco crib please view the Consumer Product Safety Commission web site to see if you baby’s crib is included in the recalls.
