Let her be/rest.
This is very difficult to determine the best direction to go in.
If she is not in pain, it might be best just to leave her alone. She is going through a lot and probably has a great deal to think about, not to mention the effects of her care. It night be good to talk with her about some of her possible concerns, etc., anything to help put here at ease. Spend as much time as you can with her.
