In 2016, Skye Savren-McCormick was diagnosed with juvenile myelomonocytic leukemia just before her first birthday. Savren-McCormick received her first transplant later this year from 26-year-old Hayden Hatfield Ryals.
Ryals later resorted to Savren-McCormick and her family through Be the Match, the organization through which Ryals donated her marrow. The families stayed in touch, and Ryals invited Skye to be in her wedding on a card she sent to the toddler on her third birthday.
The two met for the first time during Ryal's rehearsal.
I dropped to my knees and all I could do was smile, "said Ryals ABC News.
During the ceremony, Savren-McCormick" stepped out and picked up a huge handful of flowers and threw them to the floor "According to the toddler's mother, who said she was told everyone in the room was moved to tears by the toddler's story.
