Wow - thanks so much everyone. These are all great suggestions and comments. Lots to think about.
Incogneato - I guess I didn't think that all DD4's needs would be met at his preschool, considering that it's just 3 hours/twice a week. But I guess I never would have expected to have to worry about his intellectual needs this early either! That's probably why i'm kind of freaking out about what "real" school is going to be like for DD4. Especially since he has a January birthday, which means if he starts school when he's supposed to (K at age 5), he'll be one of the older kids. I really want a school to be a place of learning, and I can't imagine it being so if he continues progressing the way he has been. The few comments i've had from teachers in the district are along the lines of "don't worry, my kids were early readers too, and they were fine." But i'm starting to rant now...
Wren - I'm pretty sure the school will be an accredited Montessori. They are getting a teacher from a Montessori training school for the first year while some of the school district's teachers will be training there for the next years. But now that I read the comments from everyone, i'll have to make sure the program will be flexible.
I'm feeling more comfortable with our current preschool teacher. It sounds like it's not that easy to find someone who "gets" your gifted kid. The idea of getting a babysitter sounds good too. We've been lucky to have grandma available, but she is less so now (which is why i need the breaks!)
You've all given me plenty to think about in the beginning of the search for appropriate education. Thank you.
