Go to bed and wake up at the same time every day. For children, have a set bedtime and a bedtime routine. Don't use the child's bedroom for timeouts or punishment.
• Try to keep the same sleep schedule on weeknights and weekends. Limit the difference to no more than about an hour. Staying up late and sleeping in late on weekends can disrupt your body clock's sleep–wake rhythm.
• Use the hour before bed for quiet time. Avoid strenuous exercise and bright artificial light, such as from a TV or computer screen. The light may signal the brain that it's time to be awake.
