A very needed piece in my eyes. Thank you. 
I am not quite sure how to put this and maybe you can help. Correcting a child through religion, such as, "God is hurt when you do this or that"  or referenced wrong via Commandments. Even placing the WWJD protocol on a child does not seem right. Let the parental role be a direct relationship with the child, not a surrogate one where the Bible is the rule giver and judge. Show the child that moraity is based on caring, not a code or ideal to follow. I feel that if the child has that primary ground of knowing a loving parent, as you pointed out, placing their trust in a loving God will be more inviting.
