The kids' age is another situation that keeps things ambiguous. True, it could indicate that it's reality. But, Cobb could easily dream, in this his perfect dream, that they are two years older, as they would be in reality.
Except that Cobb throughout the film only dreams in memory, and he has no memory of his kids being the age they would be two years after he left. Unless, of course, the catharsis he received by finally letting Mal go allows him to dream normally again.
