A corner assembly for a foldable child enclosure includes: a corner cover attached to a side post of the foldable child enclosure; a first rail cover mating with a first opening in the corner cover and attached to a first upper arm of the foldable child enclosure; and a second rail cover mating with a second opening in the corner cover and attached to a second upper arm of the foldable child enclosure. The first rail cover and the second rail cover move relative to the corner cover as the foldable child enclosure is moved from a folded position to an open position.
