Lincoln Seay of Anchorage, Alaska, was born with a severe heart defect and had been waiting for a new heart since November. The baby's quickly deteriorating health had his doctors and parents worried he might die before receiving one.
But on February 19, the infant, who seemed only days away from death, miraculously acquired a healthy heart from an anonymous donor.
"Those last two days, you could just tell they were his last days," Lincoln's father, Rob Seay, 37, told the Seattle Times.
The baby boy's skin had acquired a bluish-purple tint and he was spending most his days sleeping before the successful transplant took place.
"He was right on the edge," Seattle Children's surgical director of heart transplantation, Dr. Michael McMullan, told the Seattle Times.
"We have a list of patients and he was the one we were most worried about," the doctor added.
Due to strict organ donation privacy regulations, Lincoln's parents do not know where his new heart came from – only that it came from another child who was roughly the same size as her son.
Lincoln's mother, Mindy Seay, 35, penned an emotional letter on social media to the anonymous family of the late child.
She writes, "You and I may never meet, may never speak, may never cross paths, but we will be connected on a divine, spiritual level. Your child and mine will be forever entertwined as the heart that grew in your womb now pumps the blood through the body of the child created in mine. They have merged in a way, and your child will forever live on in mine. When my child bleeds, I will think of you. When I bandage his scraped knee, I will think of you. When I hear his heart beat, I will remember you. When his eyes flutter closed as he falls asleep, I will remember your beautiful child. I will say prayers of gratitude and blessings over your family, often. I will treasure the gift you've given. I promise.
"I am so very sorry that your child's journey ended so soon. I am so very sorry that you endured life's greatest grief. I am just, so very sorry. But I hope that in your sorrow you can take comfort in knowing that you gave life. You gave life to other children. You gave comfort to other families. Your sweet child can live on in the lives of others. That is the greatest gift anyone can ever give. And your child gave that to my beautiful boy. Your child gave that to me. To my family. Your selfless act kept our family whole and spared me, a mother you've never met, the same grief you had to endure."
Lincoln's parents say their son is "doing incredible," and will be moving from the ICU to the regular hospital floor in the next few days.
"My baby is coming back. He has a long, hard road ahead of him, but his progress is amazing," Mindy shares on Facebook.
