Actually, they both know that their birthday is on May 26, but Connor is obsessed with letting people know.
Today they were at the Wild Animal Park with Mommy and Grandma (Baba-Ann). Some random comes up and asks, oh, how old are they.
Connor's instant answer: "2...almost 3 (struggling to show 3 with his fingers, holding down the pinky with the thumb is still a bit tricky) like Rand....May tenty-six..."
What a nerd.
