There was an editorial mandate not to mention Steph's pregnancy or baby during her Batgirl series.
That's been the stated reason, more than once. And really, seeing as how he has a repeat Rogues gallery, he doesn't enable most of the criminals he faces to go free
I don't think he should be. I prefer Johns' stance, that Batman provokes his rogues to focus their attention on him, instead of spawning them himself
Honestly, This is a major reason why I hate ANY kind of storyline like the Superhero registration act.. or whatever they're doing now that makes it illegal for kids to be super heroes...
It has ALWAYS BEEN ILLEGAL TO BE A SUPERHERO!!!! The cops may not push the issue because the bad guy was going to kill a bunch of people... but at no time in any universe has it ever been a 'right' to wear a mask and punch people in the face. The Avengers were a gray area for a long time but they had to jump through a lot of government hoops and background checks to get their clearance... and the authorities cut them slack becuase the cops are useless against someone like Kang the Conquerer.... but masks, secret identities, and brawling in the street is always illegal.
Honestly, the moment I found out they decided to make them gave the baby away, I knew those babies will never be mentioned again unless they want to make them return as a teenager, angsty or angry. That's just the kind of story I assume they don't want to write in a superhero comic, even before reading it.
I was surprised they even brought the possibility of a baby up, and when I found out they gave it away, I was like... oh. That's more like what I expected.
You can handwave some superheroes, though, in a manner you cannot handwave Batman.
Spidey and most superhumans, typically, stumble across villains too powerful for the cops to handle without massive loss of life, same with Thor, Superman, etc. Functionally speaking, they're firefighters, addressing a threat as they see it and then going on their way (typically. Not always, but typically). They possess powers far above human enabling them to handle a crisis quicker with far less loss of life.
The same can't be said for Batman and his clan, though. They are exceptionally trained, but still human (within the confines of comics). And they are always involved in investigations, usually involving breaking and entering, assault and battery and I'm sure a few privacy invasions besides (is Gotham a two party consent state?)
I mean the thing with kid heroes is more if they are human. Look at the Robins. They are in more danger when their first started. I mean dead children doesn't look good. No one is going to go after Batman for Robin dying. Than again they could.
