Number one thing I do to feel more organized is wake up before my kids! Give myself 20 mins (or more) to wake up, get ready, and take a look at my calendar. Also taking time Sunday night pick out clothes for the kids and put each in a tshirt organizer hanging thing in the closet so I can also see if there are gaps and I need to do extra laundry for a certain uniform/outfit. Also taking time over the weekend to plan out all dinners and lunches for so then I can do a grocery order and pick up Monday morning after drop off!
I use the Cozi app for calendar, grocery lists, and recipes and my husband is in charge of adding anything that he has that breaks from our normal routine (work travel, happy hours, etc). If it’s not on the calendar, it’s not happening!!
But honestly when with all that, so much is just rolling with the punches and knowing that something will come up or get canceled and not everything will go to plan!
