When I was a little girl, I used to love to read the Goofus and Gallant cartoons in the Highlights magazine. I'd often poke fun at the cartoons, dramatically acting like the characters, but the lessons are timeless and help to promote good manners.
This placemat has good and bad manners on opposite sides. They make excellent talking points while at the dinner table to discuss what is and is not acceptable. With my girls, I try to emphasize one key point each month with them and focus almost exclusively on an area that could be improved, such as sitting up straight. This limits my suggestions to a few and helps me to focus on the positive instead of constantly nagging.
How do you promote good manners at home and in restaurants with children of your own or children you know? What are some of the worst offenses you have seen by children (or adults!) at the table?
