Whenever people ask me how old Jack is I respond 2 and a half. When ever people ask Jack how old he is he says 2 and tries to hold up two fingers. That is until the last few weeks. Now, when people ask him how old he is he says "I'm two and a half."
The other day a friend said to Jack are you 2? And he said, and a half." And if he doesn't think they hear him he repeats in a loud voice "AND A HALF."
