I should add that Montessori would have been a disaster for my DS. He's never met an object that he couldn't repurpose in accordance with his interest du jour and doesn't take direction well. A very different personality and learning style than my DD.
As Dude mentioned, there are other Montessori threads on the site and it may be worth reading them for the personality/learner profiles of the children to see if your child fits more with those who thrived in Montessori schools or those who did not.
