CHATTANOOGA, Tenn. — A Tennessee family was told four months into their pregnancy that their baby would not survive because of a rare, deadly brain disorder but they decided to carry the baby to full-term for a selfless reason.

WTVC reported that Krysta Davis and Dereck Lovett’s daughter, Rylei Arcadia Lovett, was born without parts of her brain and skull. But doctors told them that her daughter’s organs could be donated to other children, if the baby was carried to full-term.

“We only had two options. We could have her now or carry her to full-term,” Davis told WTVC. “If I wasn’t able to bring my baby home, at least others could bring theirs home.”

Rylei was born on Christmas Eve and was only expected to live for 30 minutes. She beat her own odds and lived for a week – taking her last breath on New Year’s Eve night.

“Having a week with her was more than we could have ever expected or imagined,” Davis told People magazine. “We were able to fit an entire lifetime of love into that one week with her that wasn’t promised to begin with. She just smiled the whole time. She was such a good baby.”

Before she died, she was able to donate two heart valves to help two other children who need them and her lungs were donated for research and development of Anencephaly, WTVC reported.

“It’s been really hard coming to terms with the fact that she’s really gone. But it’s also been a great month that we’ve got to share her story,” Davis told People. “It warms our hearts to know that [Rylei’s life] will give two other babies a second chance at life.”
