Some girls are night owls, others need to be in bed early. The only way to keep the peace is:

  1. Provide quiet activities for the evening, such as card games, puzzles, badge work, and 'girl talk' to help them wind down.
  2. Plan physical activities that really get them moving for the time leading up to dinner, so they are all exhausted and will go right to bed.
  3. Make them all go to bed at 9pm.
  4. Know your group and keep your plans flexible for the evening. If some want to stay up, provide options so they won't disturb those who want to sleep.
