I have a 2 1/2 year old who goes to work with me at a child care center. He is doing fine, but my husband and I would really like to put him in a Montessori environment. As I look ahead to pre-K programs, I realize he will probably need to be put on a waiting list. Any experiences you have had with Montessori preschool programs would be appreciated. (We're not opposed to religious-based Montessori programs, as long as they use certified instructors.)
