I don't know where in town you live, but my children go to Paradise Valley Cooperative Pre-School by Tatum and Shea. (www.pvcschool.com). My oldest daughter is 4 1/2 and she has been there 2 years and loves it and my middle daughter is 3 and has been there 1 year. They both were in the 2s class for their first year. I think it is a great comfortable school for little ones and one of the few places that take 2s that are not potty trained. The spaces fill up quickly though so if you are interested you should contact immediately.
I am the mother of 3 wonderful girls - 4 1/2, 3 and 1.
