Kenna Moore was born 16 weeks premature, weighing just 9oz. This is the same weight as an apple or a peach.
Doctors gave her a 10 per cent chance of survival, but despite the odds stacked against her, she is almost ready to leave hospital and go home to her proud parents, Nicki and Sam.
"They gave her less than a 10 per cent chance," Nicki told WBTV. "Doctors are a lot of times bound by what they've seen and bound by science. And you know science says a lot of this isn't possible."
Nicki also told the channel about her amazement when doctors told them Kenna would soon be allowed home, after four months in hospital in Charlotte, America:
"[They said] Well, let's talk about Kenna going home. And I was like, 'You said the H word! You said the H word!'"
While doctors are still unsure if Kenna will have any medical problems later in life, she now weighs 3lb, 8oz, and has been moved out of her incubator and into a cot.
