Abstract: A protective crib liner for a child includes a full protective liner configured to surround an inner length and height of the crib and to wrap-around a top perimeter portion of the crib. Up to eight fasteners may be affixed to the liner to secure it to the crib. Tethers attach child development items to the liner and extend through the liner to tie around a portion of the crib. The items are attached at various heights to stimulate the child's mind, motor functions and senses. A pocket hanger attaches to the top of the liner and hangs on a top perimeter of the crib to secure the pocket hanger and the liner to the crib. A method facilitating the child's development includes attaching the development items inside the liner at various heights the child may reach thereby encouraging the child to move up, down and across in the crib.
