My 4 yr. old daughter goes to Chesterbrook (rt. 59 & Rollingridge). She has learned a lot in a short time and loves it. Teachers are great and caring. It was between there and Peter Pan, which I liked to but wanted a more learning structure. You may want to check out Peter Pan they offer more of a play-setting. We felt our daughter needed more structure since this was her first time in a pre-school. You will enjoy Naperville and there are plenty of schools to check out.
