Ask her to keep a diary. After a month, ask if she can share some of it with you.
If she objects, it may indicate that she has recorded her feelings.
If she just shows you whatever she wrote, and it contains her feelings, father and daughter can have a laugh together.
If the entries are just laundry lists of what she did, you should be concerned. What feelings does she have, if any? Is she willing to commit those feelings to paper, if not, why? Does she have difficulty express part or all of her feelings?
Take her to a local animal shelter (call ahead to see if they accept donations of money or per food.) Visit pets waiting to be adopted. It's up to you whether to tell her the fate of those pets. You can observe quite a bit there.
Nowadays, life is too easy and comfortable. Kids do not get a chance to know what suffering and survival look like. Learning some sympathy and empathy is a good thing.
Have her read something spiritual.
