"Sara Terry's first clue that something was wrong with her son, Christian, came just three weeks after he was born."

"'We went to check on him, just like any parents go and check on their kids just to make sure they're breathing,' says Terry, 34, of Spring, Texas. 'And we found him in his crib, and he wasn't breathing. He was blue.'"

"She and her husband were horrified. They rushed Christian to the hospital and learned he had several medical problems."
