My DD will be four in October. On Friday my husband and I are planning to check out a close-by Montessori Preschool. I have heard so many great reviews about them and am thinking of having DD go twice a week. Academically, I don't expect for her to get too much out of it because she's at a 2nd grade level. I am more wishing her to go for the social aspect of it.

The only issue is that she is also socially mature and prefers much older kids-- 5 and 6 year olds. I am worried about whether this will be a waste of time and money. From what I've been told... the preschool automatically places the kids based on age. This means she'll be put into a classroom with other 3 year olds.

So... I am wondering... for those of you who have had/do have your kid(s) in such a Preschool...

Is it working out?
What issues have come up?
Did/does the easy stuff bore your kids or do they just shrug them off?
How did they fit in socially when they're cognitively way ahead of the rest?
Is it common for the preschools to move the kids into the higher classes (in this case Pre-K for 4 and 5 year olds)?

Thank You in advance!
