Andrea Sutton, a mom in Firestone, Colo., was trying to put her 3-year-old son Daniel down for a nap, but he wasn't having it. It was January, too cold for him to burn off much energy outside, and he was restless. She read him some books to settle him down and then left him to fall asleep.
She returned with her 4-year-old daughter a little while later to check on him. They found him hanging from the cord of the window blinds, wearing like a necklace the V-shaped strings above a wooden knob that lowers when the blinds go up.
