Creating "Your Here" Menu

I’m working on a wordpress site and would like to create a special “Your here” menu at the top of my pages.

On my wordpress website I use just parent pages and child pages instead of catagories and posts. Therefore on my child pages I would like the code for this…

Site Name – Parent Page – Child Page

Each would be a link to the specific page that the visitor is currently viewing. Something that looks like this…

Can anyone advise me on how to make this?

Thanks in advance!
