We’ve recently started a tradition in our family of a once a month silly dinner night. It got started because the kids were so tired of being told to mind their table manners, so we declared one night a month to be freer (not completely free) than usual from the usual table manners rules.
It has now migrated into a silly dinner night.
It’s lots of fun and doesn’t have to cost anything more than a regular dinner. We choose a theme for each one. Last night was breakfast for dinner. Next month it will be dessert first.
