"An alarm sounds on Ed Damiano's night stand in the middle of the night. He jumps out of bed and rushes into his son's room next door."

"His son, David, has Type 1 diabetes. The 15-year-old sleeps hooked up to a monitor that sounds an alarm when his blood sugar gets too low. If it drops sharply, David could die in his sleep."

"'The fear is that there's going to be this little cold limb, and I screwed up. It's all on me,' Damiano says."

"But when he touches David's hand, he's warm. He's OK. Damiano says, 'That's the moment of relief.'"

"The father has been doing this night after night since his son was diagnosed with Type 1 diabetes when he was 11 months old."
