I'm after tips too - I work 4 days with 3 dc under 5 - we manage, stuff gets done but I'm finding it stressful,I feel like I rush around all day everyday and collapse in a heap at the end of it!
Can't afford a cleaner (3 lots of childcare - ouch) but seem to keep on top of it (or have very low standards) signed up to flylady and do a room or section of house each evening.
dh having to take some time off to do diy as we have a list as long as our arm that never gets done
I start work at 7am - dh does all drop offs I do pick ups, ds1 at school and we need to get a white board up to make notes like 'don't forget school trip letter' as we're not great at putting everything in his folder and as he's only 4 he can't remember to tell us everything!
Load of washing in every day & have one in washable nappies - I never seperate colours and iron twice a week but love this job as I get to do it in front of telly 
I have literally just started doing my food shopping on line in my lunch break at work so far so good...
ditto for birthday presents - amazon
I buy loads of cards in advance - I'm also a Phoenix card trader which are great cards to have in the draw as all blank, cheap and great quality
Hairdresser comes to our house, I make sure she is booked every 6-8 wks and does all 5 of us
My main issue is cooking - I used to love cooking, I have meal and after school/pick up snack plan but it eats up so much of my time when I want to be focussing on the boys, they aren't at an age where they can really help either so they end up watching telly whilst I get cooking
ds1 has packed lunches and I want to give them a proper meal plus we all get to eat together at 6pm when dh gets home but thats the hardest bit of my day
Older 2 have swimming lessons on Monday afternoon - I hate this - I think I'll have to conceed to Saturday morning ones as taking 3 is hard work but I was hoping to keep our weekends free... swimming lessons are kind of none negioatable life skill for us too so its important and only thing they do.
If I'm totally honest I only just cope with missing my boys (been back at work since Sept) I remind myself why working is important to me and how, when I'm earning again (!), it will provide for family and I'm supporting dh too by taking some of the pressure off. I also find it hard that people tell me how hard it is/must be, not very helpful if that makes sense
I'd love to know if anyone else has any tips that would also make it less stressful, struggle to fit in clothes shopping... and it grates that I'm the planner, dh does his share but I'm the one who seems to be planning childcare, know holiday days etc, it would be lovely if it was on his radar
Oh and dh and I share an online google calender - everything is on there so he has no excuse bout not knowing what is going on and I know when he is away with work
