One-year-old Samantha was very sick and needed bone marrow transplant. His big brother was more than happy to offer his.
His name is Jameson Kessler, and he calls himself the “Marrow Man” – his baby sister’s superhero.
Before the operation Jameson was excited. “I’ll save her. I give her my bone marrow, to Samantha,” he said. “Because I’m going to make her feel better and then I’m gonna save her when she’s in trouble.”
