When Shanara Mobley found her daughter who had been kidnapped at birth, she just knew her 18-year nightmare had come to an end. But since Kamiyah Mobley reunited with her biological family a year ago, Mobley said the nightmare is far from over.

Mobley has blocked her daughter over Kamiyah’s refusal to stop speaking to Gloria Williams, the woman who kidnapped her when she was just hours old and raised her as her own for 18 years. Williams was sentenced to 18 years in prison earlierthis month.

During a recent interview with ABC News, Kamiyah revealed that she speaks to Williams several times a week.

“We actually talked today. I still do call her Mom.”

It’s a lingering relationship that breaks Mobley’s heart. So much so, that she’s issued an ultimatum to her daughter. “I shouldn’t have to compete with a kidnapper,” she said. “She has to pick one of us.”

Mobley said she feels like Kamiyah is rejecting her and it hurts just as deeply as when Williams disguised herself as a nurse and stole her in 1998.

“It’s like a tug of war between us. Whenever I feel like I’m winning her back, boom the other side pulls me down,” Mobley said through tears. “Nobody acknowledges my pain. I feel like I’m being robbed all over again every time [Gloria Williams] reaches out to my daughter.”

Prosecutors said there’s nothing they can do to prevent the two from communicating.

While Mobley was in the courtroom during Williams’ sentencing, she believes 18 years wasn’t enough, that the death penalty would have been more suitable.

Kamiyah, who is still living in Williams’ house in South Carolina, believes the sentence was fair and looks forward to the day when she’ll be released.

Mobley believes authorities should prevent Williams and her family members from contacting Kamiyah.

“When a man rapes a woman he’s never allowed to contact her again, so why can this kidnapper continue to reach out to her victim? I don’t feel that she should be able to contact Kamiyah and I don’t feel that her family should be able to contact my child. The first time round Gloria stole my baby by herself. This time round now you’ve got the legal system helping her to steal her all over again. She can reach out to my daughter every day-my sentence won’t stop until she’s dead.”

Mobley was 15 when she learned she was pregnant with Kamiyah. Craig Aiken, Kamiyah’s father, was in jail when Mobley gave birth on July 10, 1998.

“When they first handed Kamiyah to me I said, ‘Open your eyes so you can see how pretty your mama is.’ She smiled right back at me, it was the best feeling ever.”

Eight hours later, Mobley, still groggy from the epidural, remembers a woman wearing blue scrubs and surgical gloves coming into the room. She assumed she was a nurse. Instead it was Williams.  Mobley said she befriended her, talking with her, smiling at her.

“‘She seemed to be really nice and so kind but she was evil at the same time. She was a devil dressed up in sheep’s clothing. I let her hold the baby and now that I look back on that day, she looked at the baby as if she was perfect. She looked at her like, yeah, this is the one.’ ”

Aiken’s mother noticed something was wrong when she saw Williams grabbing Mobley’s baby bag on the way out of the room. The family alerted the hospital staff that something was off and they raced around trying to find her but by that time it was too late.

Williams had secretly suffered a miscarriage before Kamiyah was born. When she brought the baby home, none of her family members doubted that the child’s identity.

Last year, when Kamiyah was found, Mobley assumed that she would just come into their lives. And when they first met, the relationship seemed to be going pretty well.

The two had girls’ nights out and took a trip to a music festival.

“When we first met we were inseparable. We talked every day. I felt she would just come on into our lives. I didn’t know the kidnapper had such a hold on her.”

Mobley said she was tired of being disrespected and blocked Kamiyah’s number.

“She’s blocked now because I don’t want to argue with her. I’m tired of being hurt. I’m not saying there’s not a time that we can get closer but I really should not have to compete with that woman.”

When it comes to Gloria, Shanara said she has nothing but hatred for her.

“I pray to God He changes my heart towards you but I hate you and that hate is very, very, very strong. Help me to forgive you. Just let my baby go. Please let my baby go. If you feel any sympathy for me let her go please. I’m not saying that as a bitter, angry woman. I’m saying it as a mother was robbed 20 years ago – and still counting.”
