I thought I'd share my list of "Things to do" since we are leaving our three young daughters (9, 7 and 5) in their Grandparents care.

Create a schedule of events - I'm making a schedule in Excel of days, times and activities for the girls (school, soccer, homework, etc)
Copy of insurance card
Medical Release and Consent Form
List of important phone numbers
Add Grandparents names to emergency cards at school (if not already done)
List of household rules (just so it's in writing and no schmoozing Grandma over TV time!)
I have a few presents that I will leave each of them that they can get while we're gone... just a little something from Mom & Dad.

Hope this helps someone and feel free to suggest anything else! We leave in 32 days and I want to make sure everything is in order.
