2 1/2 is right in the window, with the general consensus being that the earlier you start, the better the results. Studies found the best results with 1-year-olds, then it exponentially decreases with each year, until there's little benefit with 4+ year olds.

We did it with Latitude [1], with the support of our allergist, who had sent his son through them with successful results. It's not covered by insurance, and is expensive in all of time, money, and attention. The field is very new and data is still sparse - our allergist actually was very curious to hear results because he's adapting his practice as new data comes out from actual treatment.
