I suppose it depends on the baby. Mine was in a large room, and developed right on time, happily, and never especially exhausted or anything like that. So I never felt she was over stimulated. If you have a good feeling about the place, and the teachers seem caring, I would try it. Stay on the lists other places, and if you find its not the right match for your family (for this or other reasons), you can always move. For now, just pick the place that you will feel beat dropping off your baby, and don't worry what about what other people claim is the right way. Babies do great in many different settings!
