I would start with telling all your current clients you have a spot. The reason I say that is because they are already happy with your care and will know others with kids in already in daycare. Every kid I have ever had start after age 2 has come from another daycare wherein the parents were not happy with the care provided. So, start targeting people who already have kids in daycare or know others with kids in daycare. Give your current clients some business cards to give to co-workers etc.
