Don't know how old your kids are - mine are 5 and 7 (p1 and p3) as well as a preschooler.
We don't have time to do anything in the morning - the school bus comes at 8.
Evenings - get in 3.30,
Mon, Wed and Fri are evenings with nothing on, and there's no homework on Friday.
Mon and Wed they come in, get changed, have snack and do homework. dd1 (7) usually has a maths sheet, or reading exercise, or some language stuff to do. Takes 15-20 mins, plus reading book. Ds (5) has to go over his phonics from school (parents all have a book to revise what they did) and a writing sheet to do - takes about 10 mins. Then they either play out or watch tv or play upstairs.
Tues is busy as ds has football practice, has to come in and go straight there, gets changed and thats it. We all go, dds and I sit in the cafe at the football place and d1 usually does her homework there. Thats a night for a freezer tea - either something I froze last week, or fish-fingers or something (so not an alpha mummy - I'm not making my own lol). Ds dos his phonics after tea.
Thurs is our hard night. the way things have worked out it is the only night they could get booked in for swimming lessons and its also the night of our church kids club. So we go straight to the pool after they get home - ds and d1 have lesson while one of us takes dd2 into the pool to play, then we get changed, are home about 5.30 and have to leave at 6.05 for the church club. They both love it, so we just get it all in. My trick for that night is that they have a hot school lunch that day (luckily there is always something fussy dd1 likes on a Thurs) and I make a picnic tea for them to have in the car - sandwiches, fruit, yoghurt tubes, etc .... and they eat it on the way home. Then we do homework between 5.30 and 6, and go out to Kids Rock.
Most nights they are all in bed at 7.30, but Thurs the older 2 are up till 8.15.
I make packed lunches if needed for the next day after they are in bed, and thats it, usually. If we're having a casserole type tea the next night I put it in the slo-cooker before I go to bed.
I have to be extra organised during college terms as I am leaving at 8.15 am myself to drop dd2 at nursery and get in for lectures. And I like to leave it all organised as our nanny is picking up form nursery at lunchtime and doing tea etc. She's fabulous but she really doesnt lke cooking (and as everythign else she does is fab I dont mind organising something for her to feed to them).
Its the food I find the most stressful tbh, but I know for the kids its getting homework done.
