Mark Driscoll gives a realistic approach to doing family devotions at dinnertime:

Step 1. Eat dinner with your entire family regularly.
Step 2. Mom and Dad sit next to one another to lead the family discussion.
Step 3. Open the meal by asking if there is anyone or anything to pray for.
Step 4. Someone opens in prayer and covers any requests. This task should be rotated among family members so that different people take turns learning to pray aloud.
Step 5. Start eating and discuss how everyone’s day went.
