I love S' school. The infant room is almost very typical of a standard DCC, but with only a few differences. There is a lot of focus on independent play, and no strict schedules. They trust that the babies will know when they are hungry, and when they want to nap. There is a 1:1 ratio of teachers/aides to infants, so there is a lot more individual learning time and a lot less laying in the swing time.
My favorite thing, though, is that everything in the classroom is at baby level. There are cubby shelves all around the perimeter, so they have access to everything in the room. It kind of teaches ownership of the space, even at that age. And the teachers sit on beanbags and not rockers, so they are at baby level, too. I plan on doing more research and taking some of the theory into account when we design S' nursery. To me, dressers and high shelves seemed silly. Why put something in his room if it isn't "his"? (You can probably tell I had crunchy parents, too.)
The true Montessori program starts once they can walk and put words together, but I really like the "intro" feel that the infant room has.
Re: s/o Montessori (tngrl3)
It's a full day provided care program, but "school" is only from 8am-noon. We drop him off at 7am, pick him up at 5:30pm. The rest of the time is still baby-led, but with no planned activities, KWIM? So there is the option of nursery school only, or full day provided care with nursery school.
ETA: I should add that during non-"school" hours, it is a 2:1 ratio, which is still good. The aides then float between classrooms and go where they are needed.
