Freezer inventory - just a notebook which contains a list of freezer contents in various categories. Always consult this before meal planning and shopping.
Two shopping deliveries each week - Saturday and Tuesday - always a shop 'on the go' for things we have run out of and fresh stuff comes twice a week. Meal plan includes lunch and breakfast as that cuts out decisions.
Batch cook things that freeze well - chill, fish pie base, sausage and chorizo casserole. Avoid anything with loads of mushrooms or peppers are they don't freeze well IMO.
Me or DH check the washing baskets every evening and get a load ready for the next day if there is one. Once washed and dried it gets sorted into baskets (one per household member), when full they go on the stairs to be taken upstairs. I have enough baskets for two per person so if the person doesn't empty theirs we can start another one before the baskets come downstairs.
5 work outfits prepped on Sunday night (right down to underwear and accessories which I hang on the hanger in PE type bags.Gym kit out the night before, along with water bottle prepped and put by the front door.
'Sunday summit' with DH every Sunday night. We go through our work and personal calendars and make sure we each know what the other is doing as we both travel for work. Also tend to check the local cinema in case we fancy a movie. Book in evenings together around work and socialising. Make sure one of us is in for the cleaner!
Salad veg prepped on Sundays and Wednesdays and put into silicone snap seal bags in the fridge so lunches are really easy to pull together - just grab a protein source and some salad and stick a slice of sourdough in the toaster.
Check the dishwasher after every meal, if there isn't enough room for the next meal it goes on. Always empty it before bed if it's been on.
Clean the kitchen as you go in my house. Gets us through to our regular weekly clean.
WhatsApp group for me and DH called insurances - contains screenshot or pdfs of car and house insurance policies plus breakdown cover. Has come in handy a number of times when we can't remember when insurances run out.
