No matter how good or bad a story teller you are, little kids (and even big ones) love hearing a story.
If your kids are young enough, or even if they're not, why not get in the habit of telling them a bed time story? My 4 year old even likes to add details of his own, like names and place and animals. And my older children love a story too, although I have failed to finish any in recent memory.
I haven't been as consistent as I would have liked in the past at bed time, but it really is a wonderful time to be with your children while they are relaxed and have dropped their guard. You will be amazed at what they open up and share with you when you spend time with them at bed time.
