According to Martha, his teacher, Xander is doing great academically. He loves math and numbers and art, and she will now help him focus more on reading and writing. He's very sweet, is a great role model and helper to the younger kids in his class, is a hard worker, has great concentration, and socially has lots of friends.
According to Delya, Ari's teacher, Ari is a very happy kid with a great sense of humor. He still has a little problem with aggression, but that is abating as his communication gets better. The big news for him: he's moving into Martha's class!! Which, at 2 1/2, is pretty young, as technically the older class is for kids 3 to 6. But he's potty-trained, listens well, and can follow a series of instructions/directions in order to complete a project, so both she and Martha think he's ready to transition up.
We talked a lot with both Martha and Delya if it was the right choice for the two boys to be in the same class, but they were very supportive. They think that it may be rough in the beginning, but that in the end Xander will thrive in being the role model to Ari, Ari will love being with his big brother, and as they'll be working on such completely different areas, they shouldn't actually overlap too much. Ari also adores Martha and isn't nearly as fond of the other Primary teacher (not that she's not a lovely woman, she's just not Martha!), so it seems like a really good fit.
And to end this school post, here's a shot of Ari in his current classroom:
