A few times a year, break one of your rules on purpose, with your children. When Kimberly was little, on the first ‘warm’ day (70 degrees) we walked around the lake and had ice cream for supper. The memories are sweet and vivid, and it’s a tradition she still practices. I didn’t worry about the calories, as we had gotten quite a bit of exercise on our walk. When good nutrition is part of every day, you don’t need to worry about an occasional wild moment. The few ‘special’ breaks’, build memories, and help teach them not to be too rigid in their life.
