The Minnesota mother who gave birth to conjoined twins at Children's Hospital Colorado in August intends to sue over the treatment of her surviving daughter.

Amber McCullough is seeking $900,000 for mental anguish, pain, and suffering, while trying to get her daughter transferred to a hospital in Seattle or Houston.

McCullough chose to give birth at Children's despite living so far away. As expected, one twin did not survive during a separation surgery at the hospital.

Documents filed December 11 by attorney James Avery (on behalf of McCullough) claim the surviving daughter Savannah (called Hannah) had serious complications mid-November and was "near death" following an issue with a catheter. Avery says McCullough's request for a doctor's help was ignored by hospital staff.

"She was very upset that her daughter's life was jeopardized while she was being ignored in her pleas for help," Avery said.

McCullough's hospital stay was officially decreased by Children's after filing a complaint with the Colorado Department of Public Health and Environment and Joint Commission on November 19, stating hospital staff resisted to help her daughter.

"She went from having essentially unrestricted access, unless there was some special consideration being given for a procedure being done, from being restricted to 2 hours a day," said Avery.

While Children's Hospital Colorado cannot release specific, confidential patient information, they did release a statement to KUSA-TV that in part explained its response to behavioral violation:

There are times Behavioral Agreements are created to provide structure and support to families and treatment teams to foster healthy, cohesive teamwork during times of crisis and stress. In rare instances, where a parent and/or legal guardian's actions deliberately violate an agreed-upon Behavioral Agreement and compromise the healthcare teams' ability to provide care for the patients of Children's Hospital Colorado, the hospital places the patients' well-being and safety first, and will take measures to ensure that well-being and safety remains the focal point. Repeated violations can lead to restricted visitation.

Children's Hospital Colorado has 90 days to respond to McCullough's Notice of Claim.
