Sort of like the difference between confidence and arrogance
it's a fine line between what is, and what isn't.
To put actual words on it, I'd say that being childlike
is fooling/playing around a lot.
Childish, is getting mad over nothing, refusing to let it slide
keeping a pointless argument going.. stuff like that.0

Childish means you are old enough to know the proper/mature way to act but you don't and childlike means you are naive.0
