Thanks so much for all your great suggestions in the comments yesterday. Amazon was especially grateful to you for all the book recommendations. I am going on a retreat weekend at the end of the month, so I am thrilled to have some good books to take along.
Perri e-mailed me this from a post she did last year on this subject. This is a very cool list of questions you can ask yourself to see how your children are doing at the heart level with specific spritual concepts. I have printed it out and plan to add some things to it and review it periodically. Check it out!
