Carlie and Alden Sprague pose with 2-year-old Mason Sprague, and 8-year-old Emberlynn Sprague on Friday at their Greenwood home. Mason was born with a condition that left him with limited oxygen to the brain. He had to be on breathing and feeding tubes, and was not expected to survive, but is now doing well. The couple's second child, Aster, suffered the same condition at birth, and died in March. The couple is are hoping to start a nonprofit that would help parents whose children are critically ill.
