Well, that is the theory. That Emma and Henry have the same birthday, based on her needing to be certain ages at certain times. I'll have to try to find the old thread where it was being discussed.

However, we know that's not the case. Emma's birthday is in Oct, and Henry doesn't mention being 11 until spring.
