I only work part-time, so I have fewer crazy days than you do, I suspect, but I have girlfriends who use this trick -
When is your anniversary year end at work? How much time off do you have left? If you can, take one, and send the kids to school and daycare anyway.
I'm personally an advocate of doing one thing for myself, when I have time. Usually, it's having lunch at my favorite not-kid-friendly burger joint. Then spend the rest of the day being productive. Make a weeks' worth of lunches. (Seriously. Go ahead and fill 5 plastic baggies with chips or pretzels or whatever - they'll keep all week in the baggies, just as well as the original bag. Get those little applesauce tubs, or string cheese, or whatever is pre-packaged that you can send. I do this, anyway, for times when I KNOW it's going to be a crazy week.) Then set your oven timer - 15 minutes MAX per room (me? small rooms, like the guest bath, get 5). Gather your cleaning supplies - including a trash bag, and a box for "things that don't belong in this room" - and GO. Go back to the really bad spaces AFTER you've finished everything, but from personal experience, spend the most time on that space that you see EVERY DAY. Maybe the master bathroom counter? Or just your sock drawer, even? Something that, seeing it clean everyday instead of messy, will feel good.
Then, serve dinner on paper plates. You just cleaned the kitchen, after all. Keep it clean a little longer. There is nothing wrong with pizza, one night a month, served on paper plates. Make pizza night a weekday, dad-working-late thing, instead of a Friday night, when you have all weekend to catch up. Do it when you DON'T have time, and then you have a deadline for homework - have to do it before the pizza gets here! - smart money says DD does it faster! Or, you can always put the pizza place (or chinese, or whatever) on your phone's speed dial. When you stop to pick up DD from your husband on work-late-nights, you can order the pizza then, and it'll arrive at your house around the same time you do.
Also, a trick we use for crazy hectic times (doesn't everyone have these?) - storytime, nightly allergy meds, and toothbrushing all happen while kids are in the bath, together. They splash and play, and all that other stuff gets done. Also, you don't say how old the "baby" is, but I've been known to clean the bathroom (well, everything but the tub!) while my kids are in the tub - too young be alone, but old enough that I don't have to have my hands on them every second.
I've also been known to indulge in a glass of wine and MY TV shows while I'm doing all of those "after the kids have gone to bed" chores. Makes them slightly more amusing, and since hubby and the kids don't like what I do on TV, well, that sort of turns folding laundry or assembling the kids' daily school folders or whatever into "me" time.
Although, as for folding laundry - I really don't see any reason why every load necessarily has to be folded as soon as it comes out of the dryer. Put it in the dryer, and go to bed. "Permanent press" is your friend. As for other things, if someone is close enough to my underwear to notice that it's wrinkled, they *better* not be thinking about my housekeeping skills. And if they ARE, then we have bigger problems.
I don't know if any of this is possible for you, but I hope there might be even a spark of a good idea there. I'm not organized, not by any means, goodness no! But I'm pretty good at LOOKING organized. Like Jo said, I just have a nice big closet - or more accurately, boxes that I shove stuff into, and throw into the garage.
Hang in there, lady. Remember, not even June Cleaver, was June Cleaver. She had a wardrobe person, a makeup person, and a set decorator to dress her and clean her "house."
