Parent Child animation

I have a 2D sprite parented to the camera. There's a point when I play an animation on the camera and still want my child to follow the camera (in 3D space). However, I also want to enable controls on my child by allowing it to rotate around a the Camera (like an orbit) with the direction keys. Everything works fine if the Camera is static however it messes up when the camera starts rotating as a part of its animation! Any help would be appreciated ?
