It might be a good idea to read them some stories from My Book of Bible Studies, or even the new Learn from The Great Teacher book. You might even be able to start a few bible studies!

My kids love The Grinch who stole Christmas, not very seasonal at the moment but they had me read it them just last week. Its entertaining because it rhymes on every page, you can pretend to have the grinches voice (I feel such a dork) and it takes less than 20 mins to read, so you can read it twice.
Not very helpful am I? I'll go with Jenny on this one, she knows a good story when she reads one..
