do grace before meals, sometimes said, often sung!
eg, to Addams family theme tune
der der der dum, bang bang (on table) x2
der der der dum, der der der dum,
der der der dum, bang bang (on table)
Lord, we are so grateful
for every cup and plateful
we thank you that you're faithful
and we're in your family
(repeat intro)
or to 1,2,3,4,5 once I caught a fish alive
1,2,3,4,5 thank you God that I'm alive
6,7,8,9,10 thank you for this food, Amen!
also always did prayers with children at bedtime when they were smaller, and do pray with them as and when now when they are worried about something, or can't sleep etc.
