There's no right or wrong way to do a meal plan. Some just make a list of meals and pick from the list and others plan for each day on a weekly, bi-weekly, or monthly basis. I plan bi-weekly but post weekly because we often have events that weren't planned for so it allows me to adjust accordingly.
For example, JMac had a procedure this week and it got us a little off track with our meals. However, I'm glad to have the meal plan because it allowed me to to pick and switch around meals that I had already planned and that he could tolerate.
