I love this lunch box printable from One Charming Party! A cute apple that says "Have a great day at school!", with an apple jacks worm coming out of it! Such a cute idea, and would be a great way to make your child feel better on their first day of school.
Here's how to make it: print out the printable from onecharmingparty.com and punch a small hole in the apple. Thread a pipe cleaner through (and make it wiggly) to make a worm and place apple jacks on it to make a nice treat!
