I don't write down every number anymore, but I do just focus on making healthier choices for everyone in my household. When I check up on my counts every once in a while, my totals are pretty low calorie (I know you don't want to count).
My nutritionist several years ago said something simple that just resonated with me: make sure your plate is 1/2 non starchy vegetable, 1/4 lean protein, and no more than 1/4 starch. This doesn't mean you need to have these as separate components, but the idea of percentages can be carried over to any dish.
How does your family do meals right now? Is there any way that the person who prepares meals for your family can tweak them so they're healthier? Simple swaps like opting for lower fat cuts of meat, incorporating more vegetables into your meals, reducing some carbs, choosing lower fat dairy, having less sugar and sugary drinks can help tremendously.
