The child membership is typically suitable for ages 7-15. A child requires a mentor to tutor him / her through the program and the mentor book is included with this package as well. The adult workbook is 95 pages, the child book is 91 pages. The mentor book is the same as the child book but has added notes to help you guide your child through the sessions. Both cover 12 sessions and are compatible to do together. Meeds for both the adult and child are included in this package. If you are purchasing for more than one child, then you only need to purchase another child's book for the second child. (You will only need one mentor book). Free shipping!
