Abstract: A cover which forms a semi-circular canopy over the top of children's crib in order to prevent accidental injuries caused by children falling out of cribs. The cover is supported by rods spaced apart in intervals with said rods attached at each end of the headboard or footboard of the crib in such a manner to allow the rotation of the rods. The cover is opened easily by pushing it back over the crib from either side, thereby giving access to approximately two-thirds of the crib so the child can be removed or placed in the crib quickly and easily. Straps are also provided which fasten to the siderails of the crib to keep the cover closed and the siderails from dropping while the child is in the crib.
