Here's a tip from Elizabeth Sautter, Director of Communication Works, that we use in my own house! This sign was created with my 7 year-old and we keep it posted upstairs and downstairs.
To help make the transition back to school a little easier, re-establish a structured routine several days prior to the beginning of school.
That might mean new bedtime and wake up hours. Post a calendar with the school schedule for the entire family to view. Discuss the new school morning and afternoon routine and write it out or create a photo schedule to help him/her to remember all of the steps. Practicing these routines could be helpful.
