Why Can't It Be More Than Once?

Padyn had a nice birthday. It was mostly normal--school, nap, "Curious George" in the afternoon. But everything was tinted with the pinkness that was her birthday. So tonight when I put her to bed, I wanted to warn her that tomorrow would not be the same.

"When you wake up, it won't be your birthday anymore."

"Why?"

"Because it's only your birthday once a year."

"Awww...but when I turn two I will have TWO birthdays!"

Not yet understanding the concept of birthday...
