The Bat-Family:
-The first side-kick, Jason Todd: The one Bruce was never a father to.
Bruce never wanted a sidekick, but when he came across a brazen young boy attempting to steal the wheels off the Batmobile, he was impressed and wanted to hone that energy into a force for good. But Jason never saw Bruce as more than a means to the end and that, coupled with his arrogance ultimately cost Jason his life. Know as the Talon, Jason was killed by the Joker, though his body was never recovered.

[CENTER]“[i]Beware the Court of Owls, that watches all the time, 
Ruling Gotham from a shadowy perch, behind granite and lime. 
They watch you at your hearth, they watch you in your bed, 
Speak not a whispered word of them or they'll send the Talon for your head.[/i]”[/CENTER]

-The first Robin, Dick Grayson: The favourite son.
In Dick, Bruce saw himself and sought to make a better Batman. After the death of his family, Bruce took in the kindred Dick Grayson and offered him a way to find peace. Dick's flair for the theatrical lent itself naturally to the role of Gotham's protector and Dick soon adopted the alias of Robin after the Merryman of Sherwood Forest.
