If I were Caleb's mom, my issue with him would be about not retrieving the ball he was playing with before coming inside, but I would only insist that he go retrieve the ball and leave Jehovah out of it. I don't think Jehovah cares that a child wastes his parents' money on toys he doesn't keep track of.
I've noticed that if the adults around a child say "please" and "thank you," the child is likely to say it as well. Dr. Laura says it is beneficial for children to believe in God, but I doubt that she means a god who watches his every move to see if he slips up in some minute detail.
