Granger Smith‘s son River’s legacy is living on.

On Saturday, the country singer’s wife Amber Smith revealedon Instagramthat they had decided to donate River’s organs — and his donation saved the life of two adults.

The couple’s 3-year-old sontragically died last monthin a drowning accident at home. That same day, the country singer, 39, shared the “unthinkable” news on Twitter and Instagram, revealing “despite doctor’s best efforts, he was unable to be revived.” River was laid to rest on June 11.

Once they had decided they wanted River’s organs to be donated, the doctors explained that it would be “quite a process.”

“The next morning family and staff lined the hall for the ‘walk of honor,’ ” she wrote. “We told them River liked to go fast, so to honor him, they pushed him down that hall faster than they had ever pushed anyone. Granger and I held each other and cried.”

“We got the letter that our tiny, red-headed hero gave life to 2 adults,” Amber continued. “A 49-year-old woman and a 53-year-old man. I cried when we opened it. Cried out of sadness & cried out of love.”

“I’m so proud to be River’s mama and I’m so grateful to God that he gave him to us for those incredible three years. I pray these two recipients live healthy, joy filled, full throttle lives just like Riv,” she added. “It was one of the hardest, yet easiest, decisions we’ve ever made.”

Amber also directed her followers toorgandonor.govfor more information about organ donation.

“I couldn’t sleep last night so I was going through photos of River. I noticed so many with this light around him that I never really took notice of before,” she began in thecaption of a photo galleryfeaturing her son.

“We always used to ask him what he wanted to be when he grew up. He never said a fireman, or police man or doctor. He always said ‘when I get bigger I reach the light,’” Amber continued.
