     Like any good mother,when Karen found out that another baby was on the way,she did what

she could to help her 3-year-old son,Michael,prepare for a new baby. They find out that the new

baby is going to be a girl,and day after day,night after night,Michael sings to his sister in Mommy's

stomach.

     Finally,Michael's little sister is born. But she is in serious condition. With alarm in the night,the

ambulance rushes the infant to the neonatal(初生的)intensive care unit at St.  Mary's Hospital,Knoxville,

Tennessee. The days go by. 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. "The medical staff just called it a miracle. Karen called it a

miracle of God's love!

     Never give up on the people you love.
