There's such in-operative faith in this site.  Really. 

Parents can help their children prepare for not just those particular but typically rare events, but also for life in general by living their faith with constancy and great naturalness.
Children quite easily absorb a supernatural outlook from parents who don't live their faith on Sundays while ranting on Monday-Saturday.
They should "run across us" in prayer...they should learn that we pray rather conversationally with our Father God. That we "refer" so many events in our lives to Him.
Children with a supernatural outlook can actually live their death quite heroically, drawing many other people to God.
