"Stay in bed until you see the sun." Gro Clock shows stars when child should be sleeping and switches to a sun when it's okay to get up. Parents set the time they want the sun to show....I wonder if this would actually work.

Simple discipline technique - being positive! I used to give time-out after time-out and this is more effective for my 6-year-old. I count 1-2-3 before moving his name down to give him a chance to correct. And an end-of-day reward is great incentive to stay in the 'Happy zone'.
