Have you thought of being a substitute at your kid's school? You'd get out by the time they did so you'd only pay daycare for the kids that aren't in school.
Or ask around and see if there's a neighbor that will take them for a few dollars an hour.
Heck, if worse comes to worse, start a daycare. I have several friends bringing in $50-60K a year plus they don't have to pay for daycare!
