I have started doing less gradually.
It started when dc's were around 8 & 14, I was fed up making their lunches every day and decided they could make their own.
A few years ago we started ordering meal kits, (hellofresh, gousto etc.) I then got fed up of choosing all the meals myself and decided it would be better to choose a meal each Instead.
Then I was the one responsible when it got delivered, checking off all ingredients and reporting if any were missing.
Now it gets delivered when I'm at work 😉.
Dh started taking over when I was cooking/prepping meals, so I just let him cook now 😆.
Dh sorts out when insurance etc. Need renewing.
I sort out mortgage renewals, utility bills, birthdays, Christmas etc.
Dh sorts out dc's hobbies and activities.
I organise holidays and day trips deciding where to go and what to do.
I mostly do all the cleaning.
Dh does mostly all the gardening.
Dc's help tidy and look after their pets.
They clean their own rooms.
I wash and dry laundry, we put our own away.
Most things are equally shared.
I'm happy with the way things are.
