Sorry for the late reply, but my daughter has started a 5x 1/2 day Montessori program for 3-6 yr olds (it is full day the last year). She will be 3 this month. She is transitioning from a daycare which had a preschool, but it was very teacher led and she was already bored with anything lesson-y. I would be pretty shocked if she is not reading by the end of this school year (not that I care, I just think she's very close to making that leap).
