LUFKIN, TX (KTRE) - Spending the day at the Ellen Trout Zoo looking at tigers, jaguars, and peacocks is a great way to celebrate a first birthday, especially when that birthday only comes around once every four years.
Sofia is a Leap Year baby.
"It's one of a kind," said Sofia's mom, Taylor Massey.
Massey didn't originally intend on giving birth on Feb. 29, 2012.
"We scheduled to induce on that day because they only did them on Wednesdays," Massey said. "The doctor was like, 'Are you sure you want to have her on leap day?' and I was like, 'Yeah bring it on!' I was ready to have her."
Four years later, their Leap Year baby is growing up into a mature little lady.
"She is very strong-willed," Massey said. "She takes very good care of her little sisters and she's very smart, and she's just our big girl."
Being a big girl is something Sofia is very proud of, insisting that she is a 4-year-old, not a 1-year-old.
"I told her I was going to get her the big one balloon but she wanted a four balloon," Massey joked.
While Monday was a huge lifetime milestone, to Sofia, it feels just like any other birthday celebration.
"She doesn't really understand it too much right now," Massey said. "She's just excited that it's her birthday."
Massey said as Sofia gets older, she'll probably enjoy the perks that come with having a birthday every four years.
"She's going to be young forever," joked Massey. "When she's 40 she'll say she's 10!"
When it's not a Leap Year, the Massey's usually celebrate on date that's close to Feb 29. When Sofia is older, they'll let her choose which day she wants to celebrate her birthday.
