Abstract: A transitional baby crib bumper for use in a baby crib comprises a plurality of low-profile, tubular-shaped bumper sections for encircling the interior perimeter of a baby crib. Each of the bumper sections is distinct and separable, and includes an outer cover and a compressible inner cushioning material for supporting a child. A plurality of fabric ties affixed to each bumper section are included for removably securing each of the bumper sections to the baby crib. Finally, each of the low-profile bumper sections is compressible under the body weight of a child for preventing said child from falling out of the baby crib.
