Once you and your daughter set up the desk as desired, make clearing off the desk part of the bedtime routine—initially, with on-site monitoring and supervision and eventually with reminders to start and check-ins when she’s finished. You may find it helpful to take a photograph of the space when you first set it up, so your child has a model to compare her work to. The last step in the process might be for your daughter to look at the photo and see how closely her desk matches it.
