Keeping them in the loop
When you get the opportunity for a night away from your progeny, before you run laughing out of the door, you have to make sure the babysitter has everything she needs: phone numbers, locations, the code to the wifi, and the password to the streaming services.
To keep track of everything and make sure nothing is forgotten why not do something like this: a wipe-clean info sheet to re-use every time. In a stylish frame, obviously.
