A Hastings woman preparing to give birth to conjoined twins in Colorado said she wants to see her two babies before they are separated and has been told one of the babies won’t survive.

Amber McCullough was scheduled to deliver twin girls at the Colorado Fetal Care Center at Children’s Hospital Colorado in Aurora, just outside Denver, by C-section on Wednesday.

Hospital officials said late Wednesday they had no update on the surgery.

Hannah and Olivia share an abdomen, liver and intestinal tract. The girls have separate hearts and kidneys.

McCullough told KUSA-TV in Denver that Olivia is not expected to survive because of problems with her heart. She has only a single ventricle and is missing valves.

“I will get to see my girls very briefly after the delivery,” McCullough said. “They will need to be intubated right away, but the doctors will hold them up real quick and I’ll get a peek.”

Doctors said it could take up to 12 hours to separate the twins.

It wasn’t until her second trimester that she learned she was carrying conjoined twins. The relationship with the babies’ father ended shortly thereafter.

McCullough has lived at the Ronald McDonald House in Aurora since early August. Her stepmother is there, keeping her company and caring for her.

McCullough’s friends organized a “prayer shower” for her before she left for Aurora.

They also gave her keepsakes that honor both babies’ lives.
