The cribs' drop-side rail can malfunction, detach or otherwise fail, causing part of the drop side to detach from the crib. When a 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 also can fall out of the crib. Drop-side incidents also can occur due to incorrect assembly and age-related wear and tear.
