Today my 6 year old son is graduating kindergarten … at the same time, my 18 year old son from my first marriage is in the hospital with his 19 year old girlfriend trying to induce labor on their baby … I am going to be a grandfather … My 2 and a half year old son likes The Wiggles, Inspector Gadget, Small Soldiers and Blues Clues. My 6 year old and 2 and a half year old sons are going to be uncles … If by chance I have another child, they will be younger than their nephew …. Is that legal?
