By laying down ironclad bedtime rules, parents can avoid the nightly discussions, negotiations, and arguments that rev kids up when they’re supposed to be winding down. However, ordering your tween to get some sleep doesn’t teach her how to accomplish this tricky feat. More compliant children may crawl into bed and turn off the light on command, but that doesn’t mean they know how to squelch the niggling worries and fears that keep them tossing and turning for long periods each night. In addition to setting bedtimes, you need to teach basic sleep skills and create the conditions your tween needs to get enough rest. How much sleep your child needs is influenced by her age, whether she is going through a growth spurt, how much stress she is under, and how much exercise she is getting. Here are some guidelines, but keep in mind that children need more sleep when they are younger, growing, under stress, and getting lots of exercise.

Age eight: 10¼ to 10¾ hours Age nine: 10 hours Age ten to thirteen: 9¾ to 10 hours

To tell whether your tween needs to spend more time sawing logs, watch for the telltale signs that she is overly tired:

Sunken appearance of the eyes Difficulty awakening in the morning Trouble learning in school Falling asleep in class Napping after school Falling asleep during car rides Irritability Tearfulness Hyperactivity Difficulty unwinding at bedtime

Being tired produces a state of tension that makes it hard to relax enough to fall asleep, so it is important to be sure your tween gets to bed when she is sleepy or she may have difficulty unwinding. Watch for yawning, a puffy face, slowed movements and speech, and lots of rubbing of the eyes. Determine the time at which sleepiness typically occurs by keeping track for a week; then have your tween start getting ready for bed early enough so that she can crawl in before she gets tired.
