I’ve found that simply writing my meal plan in a notebook or on my planning template isn’t always enough to ensure it actually gets executed! But what does work is publishing it in a prominent place where both me and my family can easily see the plan. There are a couple of reasons I think this makes a difference: it creates accountability to actually stick to the plan, it serves as a visual reminder of the plan, it keeps the family all on the same page, and it reinforces the importance of family dinners.
Have your weekly calendar start with the first day of your meal plan. I add my nightly dinner plan, plus any prep I need to remember to do (like defrost some meat!). White boards and chalk boards work well for this!
