While most 10-year-olds are out playing or doing other normal 10-year-old things, Stephanie Zamora was delivering a baby.
Stephanie, a 5th grader at Arlington, Texas' South Davis Elementary School, helped deliver her new sister on the way to the hospital.
On Tuesday morning, her mother, Sandra Zamora, realized she was about to go into labor.
Stephanie and her parents jumped in the car and headed to the hospital.
But the baby wasn't waiting.
Her mother, who was in the backseat, remembers telling Stephanie, "Help me, please."
"I didn't know what to do because the baby was coming out, so, I just got the baby out," Stephanie said.
"Everything happened fast," said Sandra Zamora.
Stephanie had quickly called 911.
While waiting for an ambulance to arrive, she relayed and translated directions from the 911 operator to her Spanish-speaking parents.
The operator told her to put her new sister in her mother's arms and make sure the cord was not wrapped around the baby's neck.
On the 911 tapes, Stephanie can be heard saying "OK" to the operator and then translating to her parents in Spanish.
"My mom says, 'Well, at least you have a story to tell you sister,'" Stephanie said.
Stephanie, who wants to be a nurse when she grows up, has been telling the story to her friends.
"They say, 'Wow,'" Stephanie said.
