Batman Eternal has some nice batkids stuff too (NEAR-CANON BABS/JASON) but as a run it's.... eh. It has some canon elements that tie into other runs and storylines, but in all honesty, I mostly skip-read it.

And lol whoops, I have... not read a lot of that, tbh. A few of the events, yeah, but, mostly the batfam side of it and not much more. XD
