Most kids don't mind seeing the same foods over and over again. In fact, some kids insist on it. Don't worry that your weekday meals are repetitious. The fewer decisions you have to make, the easier meal preparation is. You can be more creative on the weekends if you like to cook.
Quality is key.
Now, for the last resort. There are those times when the only things in sight are the Mobil station and McDonald's. Hunger is intense, those healthy snacks you packed were finished off two states back and home is hundreds of miles away. Here's where you need to approach the drive-up window with some knowledge in hand. Sometimes the most important knowledge is to realize that in the big scheme of things, a meal here and there at McDonald's or Burger King isn't going to hurt, even if it is a quarter pounder with cheese, large fries and a shake.
