She was once the smallest baby born in Texas. Now, she works in the NICU of the hospital that saved her life

Tammy Lewis was 1 pound, 4 ounces at birth.

(CNN)When Tammy Lewis was born, she was 3½ months early and weighed in at only 1 pound 4 ounces. Her family faced the harsh reality their newborn's survival rate was 5-10%.

But Lewis beat the odds and now, 34 years later, she works in the same NICU that saved her life.
Lewis' father holds her in the NICU.
"I was the smallest surviving baby in the state of Texas, at the time," Lewis said. "I was born at 24 weeks. Normal gestation is 40 weeks."
    Lewis spent the first 3½ months of her life in the NICU at Scott and White Hospital, now named McLane Children's Medical Center Baylor Scott & White. She was a micro-preemie and had tubes hooked up to her to help her tiny lungs breathe.

    Years later, she works alongside some of the same doctors and nurses who treated her as an infant.
    "I wanted to be able to give back to the patients and families in the same situation that I was in," said Lewis.
    When deciding what career she wanted to pursue after high school, it was between teaching and the medical field.
    "Once I started researching the medical field, I talked to a program director and immediately fell in love with it," said Lewis."This is where God was leading me to be."
