She's Her Own Twin

Lydia Fairchild was a proud mother who faced the most unusual of challenges. She had to fight in court to prove the children born from her body were her own. "I knew that I carried them, and I knew that I delivered them. There was no doubt in my mind," Fairchild said.

Lydia Fairchild couldn't prove her kids were her own through a simple DNA test. She fought in court to keep her children. Finally, doctors told her she had a rare disorder, chimera.

Fairchild's fight for her kids began when she was 26-years-old, unemployed and applying for public assistance in Washington state. Everyone in her family had to be tested to prove they were all related.

The Department of Social Services called Fairchild and told her to come in immediately. What Fairchild thought was a routine meeting with a social worker turned into an interrogation. The proud mother was suddenly a criminal suspect.

There Must Be an Explanation

"As I sat down, they came up and shut the door, and they just went back and just started drilling me with questions like, 'Who are you?'" Fairchild said. The DNA test results challenged everything she knew about her family. Yes, her boyfriend was the father of the children, and, yes, they were all related, according to the DNA, except for Fairchild. She was told she wasn't the mother.

Fairchild was certain a mistake must have been made, but she recalled a social worker saying to her, "Nope. DNA is 100 percent foolproof and it doesn't lie."

Fairchild was not only denied government assistance for her young children, she was now suspected of possibly acting as a paid surrogate mother and committing welfare fraud. She was in danger of having her kids taken away for good. Fairchild said before she left, the social worker told her, "You know, we're able to come get your kids at any time." Fairchild began to panic. She knew they were her kids. So she rushed home to search for photos of her pregnancy and found her children's birth certificates. She told her parents, who couldn't believe the test results.

"I thought she was joking but then she started crying on the phone. I said 'Oh, it's got to be a mistake. I was there when the kids were born. I saw them come out. I held them in my arms, you know,'" said Fairchild's mother, Carol Fairchild.
