Have a “get lost day”. Drive about 10 km. from town and to avoid sibling squabbling, taking turns, allowing them at any intersection to decide whether they want to go left or right. You might experience some local gems that you never have seen. This trip always must stop at an ice-cream store and you don’t mind the trails of ice-cream flowing down to their chin because your chariot now is equipped with Kleenex, quick wipes and especially a first aid kit to bandage any “boo boos” they get climbing the tree in the park you just came to. Assure them that there really is a way to get home. When you open a large map, have them “find” their way home.
