LOUISVILLE, Ky. (WDRB) -- Birthdays seem bigger when they only come once every four years. 

Feb. 29 brings celebrations for all those Leap Day babies in the world. Today we found a few "leapers" in Louisville.

It's a club you have to be born into -- like Isabella Maria Veyel, who was born today. Or like Lindsay Young, who turns 64 -- or is it 16? -- today.

"I enjoy it now more than ever," Young said. "Sweet 16 at this age, can't beat it!" 

As you can imagine, the members are often told they look mature for their age.

"I have heard that, and people though it was strange that I was shaving at four," said Dan Maltese who turned 48 -- or is it 12? -- today.

Leap day babies or "leaplings," as they're called, celebrated birthdays today throughout the world.

"I have to wait four years to actually have one," said Kelly Potts. "It's usually pretty extravagant: we kind of go big or go home."

The chances of being born on a leap day are one in 1,461. Still, five million people in the world belong to this club.

Among them is Dan Maltese.

"My daughter is 12 years old, so she and I both celebrated our 12th birthday the same year," he said. "She thinks it's kind of nerdy, but I think it's cool." 

Leap day babies in Louisville say it's something that grows on you.  

"At first [when] I was younger, I hated it because you tell people you're turning two and they make fun of you because you're eight years old and they make fun of you," Potts said.

"I didn't enjoy it when I was young because I always felt like I was missing out on something," Young said.

Then there's that age-old question: when do you celebrate?

"That's been a point of contention for many years," Maltese said. "My mom would not call till March 1."

Famous faces in this club include motivational speaker Tony Robbins,  actor Antonio Sabato Jr. and rapper Ja Rule.

Isabella Maria Veyel, the newest "leaper" in Louisville, was born at 9:28 Monday morning. 

"I'm excited," said Curtis Veyel, Isabella's father.

"She weighed 7lbs, 1oz, 19 inches long," said Victoria Miller, the child's mother.

And the others have some advice for baby Isabella. 

"Embrace it," Potts said.

They're words to live by. 

"You're still going to get a year older, so just enjoy it," Young said. "The date doesn't matter: it's the life you live. So just enjoy it."

There are some perks to being born on a Leap Day. Pizza Hut will give leaplings a free personal pizza. Krispy Kreme will sell you a second dozen doughnuts at $2.29.

Leap day comes once every for years to balance the calendar with the earth's rotation around the sun.
