As for what time kids should go to bed... my husband works in sleep disorders and i taught a class to the Young women of my ward this past wednesday night... Teenagers are going through growth spurts similar to what they did in infancy... they need as much as 10 hours a night, although they get far less... there are several problems that kids have at that age that are considered a "sleep Disorder" Insomnia can be treated with medication and it sounds like that maybe something that you need to have him seen for... the most important thing that i tried to express to the girls i taught this week was good sleep hygene for teenagers.. here is a list 1- Don't sleep where you spend your awake time--- meaning don't do homework or just lay around on your bed, when you do this and then try to sleep, your body doesn't know how to distinguish whether it is wake time or sleep time and results in insomnia.. or just being unable to sleep.. 2- Go to bed and arise at the same time 7 days a week.... this will help your body know when it is sleep time and when you should wake up... 3- don't eat a big meal just before going to bed, a small snack is fine 4- don't consume caffine or chocolate 4 hours prior to sleeping, these are stimulants and can cause you to stay awake longer 5- exercise during the day, but reccomended not doing it just before bed 6- don't nap during the day, but if you have to, do it at mid day... not late afternoon These are just some basic things to help your kids stay healthy, and you happy... though this is the hardest time for teenagers with seminary, work, large school load etc.. if you have any questions, let me know, we can surely answer them love faith
