The crib's plastic hardware can break which can cause the drop side of the crib to detach from a corner of the crib. When the drop side detaches, it creates a space into which an infant or toddler can roll and become wedged or entrapped. When a child is entrapped between the drop side and the crib mattress, it creates a risk of suffocation or strangulation. In addition, the crib's mattress support can detach from the crib frame, creating a hazardous space in which an infant or toddler could become entrapped and suffocate or strangle.
