Song honors a mother’s love through silent nights

"This lovely little girl is my reason for breathing."

Krystal Woodward shares the story on TODAY of her 6-year-old daughter, Vivian, who has autism, a brain disorder and hearing loss.

The diagnosis of hearing loss was in some ways the hardest for her mother to handle. "I had to come to terms with the reality that nothing I had said to her, read to her or sang to her had been heard," Woodward wrote to TODAY. Perhaps -- but I'd argue it was felt.

Kathie Lee and Hoda honor Krystal and her daughter with a special song on TODAY.
