I would like to thank everyone for their advice! We are going to give the Montessori school a try, and we have reserved the right to withdraw him (we're paying month-to-month). We'll see how it goes. Of course, the Montessori thread has given me pause as to whether this is the right course as well! However, as it is a new school and they are seeking new students (and the director seems very amenable to helping us) I'm hoping that this will be a good fit.
