I wouldn't have Dick start as Robin until 14, but lets say Bruce takes him in and trains him for a year or two at 12-13.
That puts it at about 14 years. Certainly too little for Bruce to be a true father to Dick, but I've grown more favorably to the cool Uncle/best friend dynamic rather than the parental one.
