Iím so bummedÖ

About what I thought was my best Thanksgiving Day photo day until I downloaded it to the computer and saw the very out of focus child. I knew I should have bribed them to stay down for another shot, but I was even lucky to catch this one. They were playing around waiting for breakfast and I saw them trying to make a pyramid, I ran for my camera and by the time I got to them they were ready to move on, they let me snap one picture and then one of them ran away. I still love this picture and I think I know that there is probably nothing I can do about the out of focus child, but any suggestions? Any?
