So, what is in the box? It can be anything that is a craft or an activity. (Look at all our past archives for tons of ideas.). Just make sure the box is wrapped cute so that they cannot wait for the babysitter. They might even help you straighten up the house or their room to get you out the door. I know your time is busy. What time do you have to do a box before you leave? Don't! Make several boxes on a weekend you have free time and then put them away until you need them. Place them high up in the closet so the kids don't see them.
Ideas for gift boxes: (besides our own ideas)
A recipe for play-dough and the ingredients
Small box of legos to build something cool
A new movie they have been wanting to watch
A new game board they can play with the sitter
A craft project
Any hands on project. Just make sure it is not really messy so you don't have a dirty house, or anything that requires cooking or sharp tools. You are supposed to relax, not worry.
