I had a lot of success with referrals from current clients and electronic ad systems within large companies as playfelt mentioned. Do you have a website with tons of pictures on it, because that makes people fall in love with you before they even get to your house? Don't get depressed, just keep advertising and interviewing. Sometimes there are down times and depressing times but then it all falls into place when you least suspect it. We're here for you so vent away while you keep trying. Don't be afraid to ask your friends and family members to spread the word about your daycare to anyone they know who has a new baby.
