How can I make kids go to sleep

How can I make a 12 year old child go to sleep fast

Get them up early, haha, well I don't have any kids but get them up early and try to get them to bed earlier than you want them to sleep...on average it takes a person 30 minutes to get to sleep.

Im 13 and I find that listening to an audio CD based on a book that I like gets me to sleep fast. Also if I wear a blindfold I am not distracted by everything in my room so quickly fall alseep.
Also, if I am not feeling tired at all I drink a glass of milk or a hot chocolate, it makes me so tired!!!
best of luck!

like usaflinguist has said... get him up early, and don't give him caffaine or sugary stuff that makes him hyper, simply make him do heavy duty housework (mow/water the grass) and play sports all day.. and by the end of the day... he'll be pooped out!!

You can try several things like making them have a 'fun' activity where you make them run/do some sorta athletic activity, later they'll become tired and go to sleep. Or you can try the classic of reading them a story.

You could try and make their daily schedule quite busy yet fun during the day so that way they just have to sleep! I assume their in school from 7am-3pm. Well, try to get them involved in outside activities such as softball/basketball/tennis/golf etc...some kind of league that is like from 4-6 then when they're home, they'll b hungry and finish homework/watch little tv and they should be pretty tired. Works w/my friends kids. They seem to have so much going on w/outside activities and that definately makes your body tired and naturally to wake up at 6 they know they got to sleep. Also, eating healthy keeps the body well balanced while certain junk food ingriedients may excite them and keep them up for a long time.
