The crib's drop-side rail hardware can malfunction, detach or otherwise fail, causing part of the drop-side rail to detach from the crib. When the drop-side rail partially detaches, it creates a space between the drop side and the crib mattress. An infant or toddler's body can become entrapped in the space, which can lead to strangulation and/or suffocation. A child can also fall out of the crib. Drop-side incidents also can occur due to age-related wear and tear.
