Piano-Playing Mom Serenades Terminally Ill Infant Son

Abigail Tanner is seen playing the emotional "Never Enough," from the Hugh Jackman film, "The Greatest Showman."

A South Carolina mom has the voice of an angel and wanted to use it to comfort her terminally ill baby boy.

Video of Abigail Tanner playing the piano while singing to her infant son, who is battling a rare disease, has been viewed hundreds of thousands of times. 

Lincoln, 1, is being treated at Duke Cancer Institute in South Carolina and one afternoon, Abigail took to the piano inside the facility to belt out "Never Enough" from the Hugh Jackman film, "The Greatest Showman." 

"I just love that song," she told Inside Edition. "There's a lot of joy in it. There's hope out there."

The mom of three, who has now received national attention, added, "It was just a moment between Lincoln and I."

She added: “I had a couple minutes without my kids and he was sleeping peacefully I just took a timeout play a song."

Lincoln is battling a rare and terminal form of epilepsy called malignant migrating partial seizures of infancy.

She said that at one point, her son was having more than 200 seizures a day, but he is now down to a range of 20-30. 

Duke Cancer Institute posted the video online a month ago, and it has more than 229,000 views and hundreds of comments from people around the country.
