The first 60 minutes in the morning keep our whole lives running.
I'm obsessed with coffee/espressos (Mediterranean) and don't give myself permission to have one until my morning routine is done.
I find the trick for me is to be a step ahead, that way if something unexpected happens (and it usually does) there's no mad catching up or stress.
While the DC wake up and laze about for little bit, I make beds, unload the dishwasher, breakfasts for DC, laundry on, prep ALL meals for that day (including any snacks, down to cutting fruit up) and ALWAYS make next day's lunchboxes.
It helps I wake up to a tidy house, with lunchboxes ready to go, clothes for me and DC all laid out and ready for the day.
After that, I'm allowed coffee and then I can focus on the DC. They both started reception this year and DD has ASD and is non-verbal so she needs a fair bit of help getting ready and primed for the day.
This means that most of the hard/annoying/boring prep work is done for the day, all meals pretty much organised for everyone and house is tidy. We have a lot of travelling and therapy sessions every single day so we get home late and it's important for us to come to a clean house and a nice nutritious meal.
Other than that, I have lists and reminders for everything, I organise all the birthday cards and presents for the month on the 1st, I declutter CONSTANTLY, meal plan religiously and shop online or do click and collect, we do toy rotation which means the playroom is airy, fairly empty and SUPER easy to tidy.
I also tie activities in (empty dishwasher while kettle boils, cleaning bathroom when children are in the bath, fold laundry while talking to DC, ironing while binge watching box sets, organise calendar for the week on a Saturday morning during DC's swimming lessons).
I think I'm always working towards free, leisurely time and since I can't relax if things are chaotic around me, it just works for me to get chores done and out of the way first.
Above all, I've learned to keep it as simple as possible, so we're becoming more and more minimalist and the happier for it.
