An aerated bumper and liner system for a baby crib provides increased airflow into and out of the baby crib while creating a soft pad to guard the baby against injury. The bumper and liner system includes pads with apertures that allow for added air circulation. Each pad may further include ties for attaching the pad to the bars of the crib. Support stays are included in the liner pads to help ensure that the liner pad do not sag once put in place in the crib.
