how can you add keyframes to the child mesh parented to the parent mesh ill try to explain the problem as best as I can basically I parent a mesh to another to help me in keyframing objects but sometimes I just want to move the parent mesh not the child one but when I clear  the parent the child mesh loses all the keyframes position it had, I get it is doing it because when the parent mesh moves the child meshes location stays the same, any setting or a way to to let the child mesh have keyframes even if the parent is cleared.
Around the top of your object viewport please click the options button in object mode. There should be a dropdown menu that allows you to change the transformations allowing you to only affect the parent and not the child.
