my children are 9 and 12 and both go to bed by 9 every night.the way i achieved this miracle was to say that they could go to bed when they wanted but if they stayed up after the bedtime i decided upon they had to watch grown up tv ,eg panorama etc and have adult conversation no mucking about,and no snacks etc and if they stayed up they couldnt go to bed til i did and i warned them i would wake them if they dropped off they were so bored and tired after 3 nights i havent had any trouble since,a case of you know best kids, you wont listen so you better learn - dont know if it would work for anyoneelse
