I worked full time in London with four under fives. It was chaos. Once went to work in mismatching suit jacket and trousers and odd shoes. Even worse, I once got to London Liverpool Street with a bath towel still on my head.
So, these are my top tips, and they worked for me.
Get a hanger for each day of the week for each child. I have four kids so that meant 28 hangers. Put a complete outfit (including underwear) on the hanger and then get some "over the door" hooks for their bedroom door.
When you get into this routine then when you do the laundry and ironing have the hangers ready and organise their outfits (don't forget the underwear). This also means no more separate piles of clothes to put away as well, so it is a really good timesaver.
It works really well with school uniform, or nursery polo tops.
Not ashamed to admit that I also organised my clothes in this way when I was working as well. Suit, shirt, scarf, undies, all on one hanger for the entire week. Really handy for when you go to the gym as you can just grab the hanger and fold it all into your gym bag or holdall and you can hang it up when you get there.
I used the gym at lunchtimes and not always do use the gym or go to a class. It was where I would do my weekly conditioning treatment on my hair! Non-disturbed shower time was priceless to me. This also gave me more time in the morning and evenings as well. Ditto any apppointments for hair etc., do them in your lunch hour.
Menu plan for the entire week, including all meals and packed lunches. If you get in the habit of cooking more and freezing the spare portion it really does mean less work. Invest in a slow cooker.
Bleach is your friend. Squirt in the kitchen and toilets before bed. Floorwipes become your hero as you can use them on anything apart from leather.
Most importantly, accept that it will be chaotic. Accept that everyday there will be things that don't get done. That is family life, and I don't believe in teaching kids that anything less than 100% is a possible failure. Teach them that everyday you need to "let something go" is much more healthy.
