Katherine is 79 years old and the youngest is 7 I believe. What happens when she can't handle them or passes away? I know the oldest boy is 12 so it's only 6 years until he is of age. If they could get the nanny back that they are so close to and have her co-parent in some way I think that would be the best for the children. I don't know how much contact Katherine and Joe have but I would not want Joe around those kids very often. I did hear that when Joe's in town he stays at her home. I'm sure it's massive and maybe even then they don't have much contact but I can't see how Michael would have wanted Joe to have any part in raising his kids. They sure are cute kids. Are they really not his biological kids???
