when my kiddies have moved to a bed as part of getting the bed etc i have always brought them their own cd/tape player and they choose story book tapes or cd's.

we do the bath, drink of milk and quiet games then i give a warning that it is 5mins to bedtime (quite often setting the timer on the oven) then take them off to bed, once settled in bed they get 1 or 2 stories of their choice (depending on the size of the book) the it is cuddles and kisses and goodnight, then they tell me which storey they want to listen to and i put it on their cd player and they have the book and read the story to their teddies lol - if they come out i give a warning the next time they come out then the cd player will be removed from their room and i carry through with it (no matter how much they beg for me not) - they also choose whether they want their light on or off - if it is on they still fall asleep and i just turn it off before i go to bed (we have put a soft 25 watt globe in the normal light as i have had nothing but trouble with night lights breaking etc)

my ds (nearly 6yrs old) now listens to the radio station and i turn it off before i go to bed.

this has worked for us but i know every child is different and i wish you luck.
