S.S.
I have not read the other responses. But am going to give you my own. You have let the children take over control of your home / life. You need to take it back or your going to really have problems later on. So my suggestion in the following order is to
1 make up a new routine. your kids need naps and you need to get back in control of the house. give them a nap each day and even if they dno't want to sleep put them in their beds with a book. tell them nap time is till 3pm or whatever you decide. then do the housework while they sleep/rest. if you still have housework then have them help. a 2 or 3 yr old can help dust, and pick up. if you don't have them yet buy a couple of big bins for the toys and institute the rule that toys have to be picked up before lunch, before supper and before bed. also whining and screaming is not acceptable. each time they do it they get a time out. and stick to it. it is amazing how a 2 minute time out can change a kids attitude. also I know you said you don't eat "meals" but just graze all day. This is also not good. they may be hungry all the time. start sitting them down at 7am for breakfast. lunch at 11 and supper at 5. bath and into bed by 730pm. this gives you time from 730 to 10 for you and hubby. all this disarray and craziness is going to make the kids whine all the more. and now while they are still young is the time to straighten it out. I do "big" cooking on the weekends and make enough of each thing for 2 meals. and the left overs usually can be made into one more easily. keep vegetables cut and washed in fridge so they can easily be made into crockpot meals, salads etc. make a schedule and stick to it. pick your cleaning things and separate them into days (monday is for changing sheets, tuesday is for vacuuming, wednesday is for laundry etc....) build in some outside time so the kids can run run run..... and then in for lunch and quiet/nap time. you don't ask a kid if they want to nap. the answer will always be no. just say ok new plan here you go. and when they whine you say I know your mad but this is what we are doing. and then DO IT!!!! good luck
