I shouldn't have to define myself as Oliver's dad just yet as he doesn't actually do all that much at the moment, but I know that this isn't going to take that long until I'm just going to become Oliver's dad.  It has already happened in the hospital every time we visit the staff say "you must be Oliver's dad", I'd like to think that this is because they've noticed that I have the same chin and that we both have the same frown and it isn't just because I happen to be the individual carrying Oliver in to see the Orthadontist.
