My son likes to tell people that he is 5 and a half (and he will be, next month!). Last weekend, we hung out with a little girl who told us that she is "a little bit older than 5 and three quarters." Turns out she's 5 years and 10 months!

I've noticed that most of the four and five year olds I know are pretty aware of half birthdays, especially if they're over 4 1/2 or 5 1/2! Do your kids keep track of this stuff?
