The little girl gets worse. The pediatric(儿科的)specialist tells the parents, "There is very little hope. Be prepared for the worst."     Karen and her husband contact a local cemetery about a burial plot. They have fixed up a special room in their home for the new baby,but now they plan a funeral. Michael,keeps begging his parents to let him see his sister,"I want to sing to her,"he says.     Karen makes up her mind. She will take Michael whether they like it or not. If he doesn"t see his sister now,he may never see her alive.     She dresses him in an oversized suit and marches him into ICU. He looks like a walking laundry basket,but the head nurse recognizes him as a child and shouts,"Get that kid out of here now! No children are allowed. Never disturb patients here. "The mother rises up strongly and said,"He is not leaving until he sings to his sister!"     Karen leads Michael to his sister"s bedside. He gazes at the tiny infant losing the battle to live. And he begins to sing. In the pure hearted voice of a 3-year-old,Michael sings:"You are my sunshine,my only sunshine,you make me happy when skies are gray. . . "Instantly the baby girl responds. The pulse rate becomes calm and steady.     The next day,the very next day,the little girl is well enough to go home! Woman"s Day magazine called it"the miracle of a brother"s song.
