I’d want to ask, however, how good an influence they are trying to be. Good attitudes are caught. It is not frequent that they are successfully taught by hypocrites. If the parents are worldlings, then children will see and follow no matter what they are told by these people. The spiritual equation will never add up for the children, without an independent source.
Too often the substance of faith disappears and it turns into superficial ceremony.
Good story :)
I found Bradbury's "The Veldt" to be a chilling read.
