I have the same type of program as you describe. I have 3-5 year olds, from 7-5, and we do a preschool program. My licensing regulations require me to put "child care" in my name. I cannot call it a preschool. My solution was to put a little phrase with my name. So right under the name, I have "Licensed Child Care for Preschoolers".
I still get some calls for the younger ones...but I like to think it helps filter out the babies sometimes.
