A basket in each room to chuck stuff in so at least at the end of the day it appears to be a tidy home at least.
Lower standards.
Have a big monthly or weekly calendar on the wall for you and DH to see exactly what is needed each day and also plan for a few days in advance, birthdays or activities etc. Ours is colour coded but makes life so much easier.
Annual reminders on phone for all birthdays with a week's notice to allow time to arrange card/present.
If something needs to be taken out the following day put it by the front door so one less thing to do in the morning rush. E.g. book bag, PE kit
Uniform including underwear tights etc all hung up on a separate peg in kids rooms.
Mine are 6 and 4 - in the mornings when they are ready to leave after breakfast and brushing teeth, they sit on a designated stool by the front door with shoes/coat on and wait for me. Sounds like a minor thing but has made a huge difference. Each kid stops roaming around when they are ready and means getting out the door is far less stressful.
Batch cook.
Online grocery delivery only to save time.
Meal plan on a Sunday then arrange weekly shop based on this.
Not environmentally friendly but to save your sanity. Have a pack of disposable cleaning wipes for the bathroom. Use one wipe every time you're in there. Means a big clean can wait a bit longer.
If possible clean bathroom while kids are in the bath.
Do washing daily and set it to finish in the morning. Hang up while kids eat breakfast.
Buy the Lakeland plug in air dryer thingy. Clothes dry kind of ironed if hung up properly. Otherwise no ironing unless formal wear.
For self care - get a basket for bedside table. Out your creams lotion potions, nail file polish etc in there. More likely to get used.
Self care - get IPL or the Phillips lumea, worth it in the long run.
Have a basket by the front door for charity stuff, clothes not needed anymore etc
A cordless stick hoover thingy attached to wall.
A cleaner if you can afford it and ask them to do big annoying jobs like wipe down all kitchen units in and/or out. Empty and clean fridge etc.
Again if you can, gardener or laundry service. So worth it in the early days and it's temporary until kids are a bit bigger.
When you're having a shower, 5 mins before spray the shower or bath and let it soak. Spend the first few minutes of your shower in it but cleaning and it will be easier. You then shower and come out clean and it only took a few mins extra as opposed a separate bigger job.
Get takeaway once a week
Marie Kondo or get rid of one thing a day for a month. Less stuff means less tidying!
For me and DH, all our underwear is black. That includes socks, pants, knickers, bra, tights. We wash that all together and no need to sort his socks or do separate loads.
Once the youngest is in school it becomes a lot easier!
