Fortunately, kids today with the luck - or misfortune - of being born on the 29th have tools to cope with the complex explanation for their birthdates.

For example, Michelle Whitaker Winfrey, the proud mother of a "leapling" named Miles born Feb. 29, 1992, last year published a children's storybook called "It's My Birthday ... Finally! A Leap Year Story."

Statistically, about one in 1,461 births are a leapling; there are an estimated 200,000 in the US and 4.1 million worldwide.

Raenell Dawn knows she's lucky. Born on Feb. 29, 1960, she leads the Honor Society of Leap Day Babies, a group of people born on that distinctive day. The group functions primarily through its Web site, www.leapdaybabies.com. ...

Wondering what to name your leapling? How about Leapa, Leapanne, or Leaptoria? Haven't figured out what a leapling is? According to the "leaptionary" at Ms. Dawn's Web site, it is a newborn leap day baby.
