That is a very innovative and interesting idea. It reminded me of what I did with my sons (2) when they were young.
They would complain about their bedtime (what kid doesn't) and try to do anything to stay up. So I made a rule:
They could stay up 30 minutes later, IF they spent it reading in bed.
Boy, was that a success. My active sons now settled down and started reading books. And have continued to do so into adulthood (they're in their early 30's)
Books do wonderful things.
