Most sites are dedicated to the woman and almost ignore the man's role.
This site will provide information on what is happening during pregnancy, during the first 6 months, then the next six months, and then as they grow older.
Also there will be a forum for dads to talk to other dads, and a section of general advise for each stage.
I think this will end up being 3 - 5 pages of information and that the forum will / should be the main area.
