Callen Chavez wasn’t even 1 day old yet when he started helping other people. Before Callen was born Tuesday morning, a nurse asked his mother, Courtney Bagwell, if she wanted to donate his cord blood to LifeCord, a public cord blood bank. Bagwell said she’d recently learned about the process and uses of cord blood banking in a biology class at Gainesville State College where she is studying to become a nurse.
