Just to hear tiny Sariah Burrell cry is remarkable. Born three months early six weeks ago, she still weighs under two pounds.

"It's been a miracle, really,” says Sariah's Mother Charmecia Burrell.

A miracle, her mother says, because nobody was sure she would survive.

"At first, initially, they didn't even think the tubes would fit in her. So we were preparing for the worst,” says Charmecia.

At first, doctors put Sariah on a ventilator, a breathing machine. But after only a week, they switched to another treatment.

It involves bubbles. The bubbles, in a saline solution, allow air into the lungs through a tube attached to the baby's nose.

"We're confident this is going to improve long-term outcome for these babies,” says Neonatologist Dr. Randy Grubbs

Dr. Randy Grubbs helped bring the treatment here after he saw it used in the northeast.

"It was incredible the first time I saw this system in practice, for a tiny, premature babies. I was amazed it would work as well as it did also,” says Grubbs.

"So far, it's still a long journey, I'm just glad she's doing good so far,” says Charmecia.

Now, Sariah is breathing on her own, with no help, even from the bubbles.

"It's been a long roller coaster ride. But I'm just happy she's progressing so good."
