Oh Newsarama, you disappoint.
Anyone with any shred of Batman knowledge knows that Damian Wayne is not—by a long shot—the first to raise the question: ‘What would it be like for Batman to be a father?’
Throughout Bruce Wayne’s history (prior to the New 52 anyway), the very first ‘son’ that he raised was Dick Grayson, who turned out very well in adulthood. If you go way back into the history of the character, he originally raised Dick since he was 8 years old to adulthood. In the post-Crisis history, he also raised two more sons before the arrival of Damian: Jason Todd and Tim Drake.
On the front of Bruce Wayne being a biological father, that too was already explored with Helena Wayne who was his canonical daughter from 1977-1986 prior to her revival in 2005, and her full reinstatement in the New 52. He was literally there from the time she was conceived to the time she graduated college with her law degree. He raised this young woman from the day she was born to the day she left the nest (oh yes, I went there) and established both a career for herself and her superhero identity. All in all, history has consistently told us since 1940 that Bruce has never been a bad parent.
Long story short, Damian Wayne is not the originator of Batman being a father nor is he the first canonical child he’s had. At best, he was the first canonical biological son he’s had in the mainstream continuity, and at best he raises the question of what it would be like for Bruce Wayne to be the father of Talia Al Ghul’s baby.
[Edit]: For the record, I didn’t forget the fact that Bruce also adopted and raised Cassandra Cain. I was specifically answering the question posed by Newsarama about ‘how Bruce would be as a father, and what kind of son he would raise.’ Since the focus seems to be on the fact that Damian is Bruce’s biological child, I felt it was worth noting he had a biological child before him, who happened to be a woman. Just making that clear!
