Plan everything the way you want it to be.
It might be that not everything you plan actually comes to fruition. Such is life. But unless you actually have a plan, whether you achieve what you want is completely left to chance. You know what they say; a goal without a plan is a wish. And you can probably do better than that! When I’m working with busy mums like you, planning is THE thing that makes the biggest difference.
That means planning not only your meals but also when you will exercise, when you will do those ‘mummy admin’ jobs and when you will take time out for yourself to relax and recharge your batteries. It probably makes sense to start with planning family mealtimes and what everyone will be eating when. If your house is anything like mine, there will be almost constant requests for what the menu looks like on a particular day. It is very stressful not to know, not least because you will continue to be pestered. Better to have it all figured out ahead of time.
Plan your planning. When will you sit down to plan the weekly menu? Try to pick a regular time each week so it can become a habit. Write down breakfast, lunch, dinner and snack options for everyone.
I find it easiest to start with main meals so that I can plan to make leftovers for lunch or to form the basis of another meal (roast chicken, for example, becoming the basis for a chicken pie).
