Until you figure out what you can do, arrange for someone you trust to come over, play with the kids, and let you take a nap.
Even if you only get an hour, that's an hour you didn't have before. Being able to think while you're taking care of your kids is important. When something out of the ordinary happens, you need to be able to function and think clearly.
LIke today: We just had high winds come through and drop four of our neighbor's trees on the lawn. Pretty much a no-brainer, but had they been angled at 90 to the house instead of nearly 180, we'd have had one very smushed house. As it was, DS and I had just popped out to the library, and he didn't take a nap until we got home - and discovered Sherwood on the lawn.
Good luck, get a nap, and you'll figure this out soon.

PS: Cereal does not guarantee sleep. They are 6 weeks, I would invest in a couple of swings (or one if you can't afford two for the baby that stays awake). They outgrow them before they can be addicted. :) No, it isn't a bad habit, but your lack of sleep might give YOU bad habits!
