Channel 4 wants to get Britain's children to bed on time. Tackling every problem with invaluable tips and simple but incredibly effective techniques, the plan is to get the nation's under-10s to sleep by 9pm and to look at just how much sleep our teenagers really need. Together we can win the Battle of Bedtime. Bedtime Live puts sleep-deprived parents to the test to find out who's more lethal behind the wheel of a car - a drunk mum or one that's sleep deprived. Bedtime Live also focuses on how teenagers might not be as lazy as their reputation would suggest, putting to the test teen sleeping habits, study techniques and obsession with modern technology, to show that just an extra half hour's sleep can easily push that GCSE B to an A grade.
