Jack v. Will

I keep calling Will "Jack." And I don't think its just because I have been trained to say Jack's name. As in...."Jack, stop that." "Jack, put that down. " I think I have been calling Will "Jack" because he looks a lot like Jack when he was born, though Will has blond hair right now. The only other difference in the 2 is the chin (Will is rocking the dimple chin on the right). See for yourself...
