Anything Goes Night
This is an excellent alternative to family fun night which all will enjoy. Once a month pick a day of the week where everyone is allowed to set their own rules. Try to schedule it over a weekend because on this improvised spin on game night, your kids get to pick their own bedtime, activities, and meals. A broad set of ground rules can be established for safety but try to keep things open-ended and the whole family has some alone-time for whatever they want.
