A Kansas couple is expecting twins, one boy and one girl, but their joy soon turned to heartbreak when they found out one of the babies was not thriving.

A doctor told Ian and Brittani McIntire that their little boy, Mason, has a hole in his heart and his brain has not developed normally.

Further, the little boy is not a candidate for surgery because of his brain abnormality, KWCH reported.

"He's only weighing nine ounces and his sister is over two pounds, so big size difference," Brittani said.

"His only chance of survival would be heart surgery, but they wouldn't do heart surgery on him because of his brain," she added.

Tuesday, they received a glimmer of hope thanks to a sonogram image.

The small, black and white photo showed baby Mason with his tiny hand wrapped around the finger of his growing twin sister Madilyn.

The technician told the couple to look at the image, their unborn son was holding his bigger sister, Madilyn's, hand, KWCH reported.

"Most twins, when she's trying to take pictures and stuff, they're kicking each other and hitting each other and she said with our twins it seems like she was very protective over him," Brittani said.

Doctors do not expect Mason to survive, but his parents know he will be protected as long as he lives.

"I know I'm holding him, I'm carrying him, but I just want to be there for him. And she's the only one who can actually be there and holding onto him through it, so it's comforting to know that if he does pass he won't be alone," Brittani said.
