The nursery drop off and pick up is a rush, it just is, you will find yourself driving along glancing at the clock and praying that you don't hit a red light because then you might not make it on time. Just do the best yo7 can to leave on time, set clear boundaries with work and stick to them.
Then for the rest it's about being prepped.
I use a bit of the weekends to get ahead for the week, so
- a weeks worth of washing done and 5 outfits picked out for DD and set out ready so that I know every morning that that is ready to go.
- Something batch cooked and stuck in the freezer in portions so I know that if I don't have time or energy when I get home to make dinner there will be something that I can just microwave defrost and still eat well.
- bigger housework would be done at the weekend, weekdays just surface level stuff.
Spares/nappy bag was always packed and restocked the night before so I didnt have to sort that out in the morning. I also kept a bag of nappies, a pack of wipes, a change of clothes, a towel and some slippers in the boot of the car. That way if I ran out in the spares bag (or forgot it) or there was an unexpected poosplosion/vomit session/threw themselves face first into a muddy puddle type situation, I had what was needed to get them home.
It's really important to make sure the split of work in house/admin/kids stays 50/50 with you and your DO, don't let it slide, you are both working FT, you need to be equal partners.
It's also important to be realistic, you and your kids are busy all week, you don't need to fit 'making memories' type activities in every weekend, we all need to just slob about and recuperate sometimes, so have a day doing nothing but snoozing in the garden or watching TV in your PJs if you need it.
Also Stuff on Toast is a valid, healthy, filling meal. Don't let anyone make you feel that you need to do a full 3 course home cooked meal every night, designate at least 1 day a week to be a 10 minute meal - omelette, stir fry, stuff on toast, pesto pasta.....
