Pick one thing that you usually do for your child in the morning and let them take charge and be responsible for it. Making sure they have everything for school? Encourage them to prepare the night before and have their bag ready. Making lunch? Teach them to do this and again, work on it the night before. Tell them that you trust they can do this!
Ask your preteen: "How can you use what you have responsibily?" Encourage your preteen to think of things other than physical items; such as, a good work ethic, intelligence, being friendly, etc.
