My son is in the 3s program and loves it. He looks forward to preschool and he has already acquired many important school readiness skills (taking turns, sitting during circle time, independence, following along with the group, etc...) in just the few short months we have been there. I think the program is a good balance of play-based learning and outdoor breaks (its close to Lincoln Park so classes take walks and visit the playground/zoo). The lunch program is healthy and organic.
