What ironing?
Ironing is one thing you should not be doing. Either find someone to iron, or get a dryer and use dryer sheets. Take the clothes out of the dryer and fold very neatly. You may have to get rid of clothes that really need ironing and buy only things that are trouble free.
If you don't have a dryer, get one. And a dishwasher.
My DCs have no uniform for secondary and they can do their own laundry themselves once they get to 11-12 ish. For the one still in uniform I have three knit not woven shirts for her and one skirt. The skirt is easy care polyester or something like that with pleats that it would take a tornado to shift. It goes in the washing machine and hangs to dry overnight. Usually once a week is fine for the skirt. The shirts wait until the weekend or if DD4 wants she can get the two older ones to drop it into their wash. (They arrange that one bungs it all in the machine and the other puts everything in the dryer. Then they both sort and fold). They take off uniforms when they get home and that saves washing. They have plenty of slouch clothes to slouch around home in.
The DCs are all responsible for all the things they need for school being ready in the morning. I do not look for shoes or homework or stuff they were supposed to bring. Tough if you have no idea where it is. You had all night to find it and leave it ready. I have made them get themselves organised form when they were about 8. I am doing them all a favour in the long run by getting them to stand on their own two feet.
It's really, really easy to get a nanny from Spain or Greece right now. They are pricing Polish and E. European nannies put of the market. However, watch out for amateurs driven by economic problems whose motivation is to leave Spain or Greece.
I cook 3-4 times a week and we have leftovers the second day. We eat whatever is left in the fridge over the weekend.
No-one takes a bath. There is no lock on the bathroom door and when your shower time is up you can expect company. Everyone takes a shower in the evening except me.
Keep a master list in the kitchen of every single thing you ever buy or have bought in the past. Do it in sections or randomly can work too, depending on what way your mind tends to work. When you go shopping, sit down with the master list first and work from the list. Keep a dry erase board or post its in the kitchen where you can write memos to self about things you are running low on. Train the DCs to leave notes about items that need to be bought too (cereal, juice, tampons, toothpaste, whatever). Don't ever go out shopping without a thorough list. That is if your local delivery service really isn't up to snuff.
Big kitchen calendar and everyone trained to use it goes without saying. Open post beside the calendar and rummage through school bags there too to keep track of school events. Have the bin within easy distance and toss everything once noted. Keep your own admin filing system within easy reach too.
If you don't have a good size freezer, get one. Freeze meal sized batches of pasta sauce. Gussy it up with cream, vodka, olives, etc when you put it in the pot. Freeze items like meatballs in meal size batches, same goes for stir fry meats. Freeze strips of cooked chicken and you can make virtually anything for dinner quickly. Use frozen veg that doesn't need prepping, esp garlic, onion, etc that goes in every meal just about...
Me time is the crack of dawn for me. I like being all alone before everyone gets up and I have my tea and toast and shower without being mithered by everyone.
