"For me, it was like this feeling that my heart finally received a piece of it back," said Erchul.
Gabriel was 4 months old when he died in 2014 from traumatic head injuries.
He had been under the care of Erchul's then-husband, who was convicted of causing Gabriel's death.
At the same time, 4-month-old Morgan was in the hospital waiting for a heart. She was diagnosed with dilated cardiomyopathy at 2 weeks old.
In a successful transplant surgery, Morgan received Gabriel’s donated heart.
For the first time, the two families met at Disney World two weeks ago.
“She just grabbed me. She wanted hugs and she wanted kisses,” said Erchul.
Erchul said it was an instant connection.
"Meeting Morgan, I was able to feel like I could just take a full breath, and a sense of peace came over me," Erchul said.
Erchul said she hopes that her son’s heart will mean a long and happy life for Morgan.
“I just prayed that they would receive all the love I had for him, and I just want her to be happy and have a good life with her family,” said Erchul.
