the binghams had three children back then. stacy was pregnant with number four and 6-year-old sierra was at a t-ball game in town across the fields there. she threw up at the game and kept throwing up at school for the next few days. said she felt cold and tired all the time so the binghams took her to the doctor who gave her a chest x-ray. >> the doctor comes in and says one of three things here. it could be a pneumonia. a form of cancer. or something called card cardiomiopathy. >> they told them to take sierra to a cardiologist. >> you hear him make a few phone calls. he was talking about this kid. another kid that was super sick and will need to go to intensive care. we thought that kid was really sick. glad that's not us. >> and then the technician came back and they understood. >> that kid was ours. >> they rushed sierra to intensive care. the diagnosis, dilated cardiomiopathy. heart failure. >> you're in a misty fog like your world came crashing around you and then just trying to put your mind around it and grasp it. fear. >>
