Can't live without it!
I have the '07-'08 version of this calendar and searched the internet to find the new one for the upcoming year. I have 3 kids and I don't think I can ever go back to a regular calendar - cramming in everybody's activities into a regular calendar box. My kids (ages 6,4,2) know how to read the calendar and can keep track of their own upcoming activities. My oldest even checks her line for "gym" days at school on her own to know when to wear gym shoes.
