What's best for a child: to stay with adoptive parents who have raised him since birth, or be sent to live with a biological parent he barely knows?

That's the question the Ohio Supreme Court is facing.

Indiana resident Christy Vaughn was the first person to ever hold three-year-old Grayson and has been the only mother he's ever known.

The child's biological mother agreed to the adoption, but just 17 days after Grayson's birth, his biological father, who lives in Ohio, began petitioning the court for his custody.

Now, three years later, the Ohio Supreme Court sided with the biological father.

"The right of a natural parent to the care and custody of his children is one of the most precious and fundamental in the law," the court ruled.

Therefore, the only parents Grayson has ever known, had to hand him over to his biological father.

"I said, 'bye, buddy, have fun at daddy Ben's,'" adoptive father Jason Vaughn said.

"I just kissed him and told him I loved him, and I walked out the door, and that was it," his adoptive mother, Christy, said.

The Vaughns have no plans to ever see Grayson again. The biological father has refused visitation, phone calls, and text messages, as well as interviews with the press.

"My client believes that any publication involving his child will further disrupt his well being," the biological father's attorney, Alan Lehenbauer, said. "My client has sought the return of his child since shortly after birth and will not re-litigate this matter in the media."

Meanwhile, the Vaughns are petitioning for a second adoption. It's something they, and their other two children, are placing in the hands of God. They also said the loss of Grayson is particularly hard on their seven-year-old.

"I want him to be praying about it and encouraged that we will see Grayson again," Christy said.
